  1. greetings, second post, first question :-) I'm designing a small breakout based on a CC3200mod, it's working ok so far (sending UDP, webserver is next). I'm very new to the CC3200, I'm wondering if there's a way to easily store / save and retrieve data using for instance the serial flash. From what I understand by looking at the latest version of uniflash, there are now additional /sys files but I don't fully understand how to access them and if it's possible within energia. If not, is there a piece of API that I can include in my energia code to access a file or store data ? it's essentially a destination / recipient IP address, UDP port, just a few settings. I was using so far either EEPROM or the code flash (reserving a segment for saved data). I'm not willing to add an external serial EEPROM. thanks for any help !
  2. Just something that might save someone from a little hair pulling. In the email CCS project, when configuring your credentials for sending email, make sure you ignore the <> in demo.config.h #define SMTP_BUF_LEN 100 #define GMAIL_HOST_NAME "smtp.gmail.com" #define GMAIL_HOST_PORT 465 #define YAHOO_HOST_NAME "smtp.mail.yahoo.com" #define YAHOO_HOST_PORT 25 #define USER "<username@gmail.com>" //Set Sender/Source Email Address #define USER_RFC "<username@gmail.com>" //Set Sender/Source Email Address #define PASS "<password>" //Set Sender/Source Email Password #define RCPT_RFC "<username@gmail.com>" //Set Recipient Email Password #define EMAIL_SUB "Hello from Simplelink!" #define SMTP_BUF_LEN 100 #define GMAIL_HOST_NAME "smtp.gmail.com" #define GMAIL_HOST_PORT 465 #define YAHOO_HOST_NAME "smtp.mail.yahoo.com" #define YAHOO_HOST_PORT 25 #define USER "username@gmail.com" //Set Sender/Source Email Address #define USER_RFC "username@gmail.com" //Set Sender/Source Email Address #define PASS "password>" //Set Sender/Source Email Password #define RCPT_RFC "username@gmail.com" //Set Recipient Email Password #define EMAIL_SUB "Hello from Simplelink!"
  3. Hello, I have being working on getting a 20x4 LCD (HD44780) working on the CC3200 launchpad and have not been able to get it working. I have found a few posts with partial code and partial libraries but have not been able to find an SPI or I2C example that works. Does anyone have a working implementation of the HD44780 on the CC3200 in either I2C, Serial or SPI mode? This is seems to be the closest I have found ( https://github.com/remixed123/CC3200-hd44780-lcd ) ... but I am unable to get it working. If anyone has been able to get this working, could you send me a simple "hello world" example. Thanks in advance for any insights or suggestions. John
  4. I was wondering if anybody used mDNS function in energia for CC3200? If yes, could you please provide a simple example. Thanks

  6. Hi All, A few days ago we release a new version of the free Visual Micro plugin for Energia 0014 and Visual Studio 2013 Community Edition. Currently build and upload appears to work identically to the Energia Ide but it would be useful for others to test. One windows users report the upload not working which we guess is related to the start path that Visual Micro uses when running the upload command. It would be really useful for a few others to test especially with the cc3200. http://www.visualmicro.com/ Here is a screen-shot from earlier Energia releases in Visual Studio 2010. We will make some new screen shots for 0014 and VS2013 as soon as we get the thumbs up from a few users. Some historic notes from earlier Energia releases are here http://www.visualmicro.com/post/2013/08/02/Energia-Getting-Started.aspx Your help will really be appreciated. Either in this forum or in the Visual Micro forum. Thanks The Visual Micro Team
  7. Hello, my plan is to use the built in serial flash memory of the CC3200 launchpad board (it holds 8 mbit, its a 25PE80VP from ST) for storing multiple GIF files. Can anyone give me a hint how to save/load from the serial flash and what is the type of file system? Sorry if its a nonsense question, i am quite new to CC3200... Cheers, Max
  8. Hi, I am just getting started with CC3200 and Energia for my very first project. I wanted to know if it's possible to use pinmux to configure pins of the cc3200 on Energia? if yes/no, what is the procedure/alternative?
  9. Hello everyone, Is it possible to create a "host name" for the wifi server running on CC3200 Launchpad?, if yes, does anyone know how or have a sample code?. Thanks.
  10. Just got my CC3200 LaunchPad and am trying to install the Service Pack (1.0.0.1.2) as described here: http://energia.nu/cc3200guide/#upgrade Apparently I can connect to the board (from UniFlash on Windows XP) on COM3, but the Service Pack installation gets to "Executing operation: Connect", then "setting break signal", and
  11. Hi, I am trying to connect my CC3200 to the home WiFi using the AP mode. I was wondering if there is any sample code for that? I have difficulty to communicate with the CC3200 webserver and send my WiFi info through the html form. I tried to use Webduino but no success. Thanks,
  12. Hello, I am having a problem getting the CC3200's built in accelerometer to transmit data over WiFi. I have the BMA222 example working perfectly and I can send static data from the CC3200 easily, but when I combine the two I cannot send accelerometer data over WiFi faster than once every 10 seconds. #include <WiFi.h> #include <Wire.h> #include <BMA222.h> char ssid[] = "private"; char password[] = "vastcartoon245"; unsigned int localPort = 2390; IPAddress ip; long rssi; WiFiUDP Udp; BMA222 mySensor; void setup() { mySensor.begin(); uint8_t chipID = mySensor.chipID(); pinMode(RED_LED, OUTPUT); pinMode(YELLOW_LED, OUTPUT); pinMode(GREEN_LED, OUTPUT); digitalWrite(RED_LED, LOW); digitalWrite(YELLOW_LED, LOW); digitalWrite(GREEN_LED, LOW); Serial.begin(9600); WiFi.begin(ssid, password); while ( WiFi.status() != WL_CONNECTED) { digitalWrite(YELLOW_LED, HIGH); delay(150); digitalWrite(YELLOW_LED, LOW); delay(150); } digitalWrite(YELLOW_LED, HIGH); while (WiFi.localIP() == INADDR_NONE) { digitalWrite(GREEN_LED, HIGH); delay(150); digitalWrite(GREEN_LED, LOW); delay(150); } digitalWrite(GREEN_LED, HIGH); Udp.begin(localPort); } void loop() { ip = WiFi.localIP(); rssi = WiFi.RSSI(); int8_t acclX = mySensor.readXData(); int8_t acclY = mySensor.readYData(); int8_t acclZ = mySensor.readZData(); Udp.beginPacket("192.168.2.197", 42679); Udp.print("{ rssi: '"); Udp.print(rssi); Udp.print("', ip: '"); Udp.print(ip); Udp.print("', accl_x: '"); Udp.print(acclX); Udp.print("', accl_y: '"); Udp.print(acclY); Udp.print("', accl_z: '"); Udp.print(acclZ); Udp.print("' }"); Udp.endPacket(); delay(10); } Any help would be appreciated! Also, this is my output. Obviously rssi and accl are all wrong, but the main problem is it took about a min to get all of that. { rssi: '0', ip: '192.168.2.90', accl_x: '-8', accl_y: '-8', accl_z: '-8' } { rssi: '0', ip: '192.168.2.90', accl_x: '-8', accl_y: '-8', accl_z: '-8' } { rssi: '0', ip: '192.168.2.90', accl_x: '-8', accl_y: '-8', accl_z: '-8' }
  13. Hi All, I just wanted to share my design with for CC3200MOD. It has CC3200MOD and its minimum requirement including Antenna, plus Lipo Charger and regulator to work with LiPo Battery. And has pin layout of LaunchPad XL. And also has pinout for Flash and JTAG I used CC3200 LaunchPad XL to program it. So far I can confirm CC3200MOD and Antenna works fine and Antenna Gain is pretty good. Here is the address and GitHub. https://github.com/alikian/CC3200MOD
  14. Hi folks I started to use CC3200 in the ENERGIA environment. I was using the examples from the Book "Arduino projects to save the world" I tested the code on an Arduino UNO board, and is OK. But in the CC3200, only one Analog channel is printed correctly, in the getADC() function, I can comment any two // ADC1 = analogRead(A1); statement and the third will print correctly I am new on ENERGIA so any help will be apreciated. The code follows: //Listing 2-4.

  17. CC3200 LAUNCHXL v4.1 ENERGIA 0101E0013 WINDOWS 7 Hi Guys, So I just got a few CC3200 Launchpads to do some prototyping on. Ultimately I would like to be able to connect onto the Launchpad without having to first go through my router. But I digress... I've been running the SImpleWebServerWIFI sketch from Energia. It works as expected when I have my computer with Chrome accessing it, But as soon as I connect with my Android phone(4.4.2) and chrome(v39.0.2171.59) and press a button the unit freezes up. Attempting to connect to Network named: WNL108 .. You're connected to the network Waiting for an ip address .

  18. Hi, I've made a very simple RTC library using the RTC method in the PRCM library. It is intended for the CC3200 Launchpad and has only been tested on the CC3200 Launchpad so far. Overview: Uses the PRCM library It follows UNIX Time It was made with the "Time" library of the Sparkcore in mind. It has the following methods:ccRTC.zone() ccRTC.now() ccRTC.year() ccRTC.month() ccRTC.day() ccRTC.weekday() ccRTC.hour() ccRTC.minute() ** ccRTC.begin() Limitations: (Unfortunately there are a few actual limitations) It is accurate to only about 4 seconds an hour. (That is pretty bad, but can it can be used for non time critical applications if time is synced with an online server regularly) My tests haven't shown any issues so far, but it is not foolproof yet. If you're using an NTP server to sync time, then you'll need to convert it to UNIX time first before you use the ccRTC.setTime() You can get the code and a basic guide from here : https://github.com/nitred/ccRTC Additional Documentation for the the functionality can be found here : http://docs.spark.io/firmware/#libraries-timeIt Its a work in progress and I know for a fact that there's a better way to do it than this but I really needed this library and I hope you find it helpful too. Any and all feedback and improvements are welcome!
  19. The Tiva Launchpads have a hardware Quadratic Encoder Interface peripheral. The documents on CC3200 doesn't seem to depict it. I had the wrong impression that CC3200 has the same kind of peripherals as Tiva in addition to the WiFI feature set. Can any one confirm if indeed hardware QEI peripheral is not available in CC3200?
  20. In the Energia port for the CC3200, will there be an avr/pgmspace.h replacement to help manage access to the program memory? If it is not already in the works, would such a thing be workable? As I understand it, the CC3200 stores program in an external memory, and loads it into RAM for execution. The AVR has two memory spaces (program and data), and on Arduino, avr/pgmspace.h defines various macros, etc. for using data in program space. Seems like it might be possible to create a pgmspace.h (and accompanying library) which would allow use of data stored in the CC3200 external memory in a way compatible with some Arduino libraries. Just a thought at this point, I have not studied the CC3200 architecture, and my familiarity with pgmspace.h is mostly in finding ways to work around it when porting AVR Arduino libraries to ARM. (Got started thinking about this because I was thinking it would be nice if Energia included a avr/pgmspace.h for MSP430 and for Tiva, similar to what TeensyDuino does. http://forum.stellarisiti.com/topic/1983-howto-porting-libraries-some-help-needed/?p=7660 )
  21. I have been attempting to work with serial communication between the board and other devices, but cannot get them to communicate while on connected to the booster pack rails. The only time I have ever gotten any Serial communication to work is by connecting a UART device to J6 & J7 in the middle. Is there a different Pin configuration I need to get those to work? I switched the jumpers on J6 & J7 down after downloading my code to the CC3200.
  22. Hi, I know Energia today and tried the example code "Blink" of Energia, but it shows "Upload failed.". More output is like below.

And I had connected SOP2-bottom with J8-top sides when using Energia. Workaround: I can use Energia to compile, and use UniFlash to flash the image to the kit. Could anyone help? Thanks!
  23. Two problems with delayMicroseconds on Tiva (and I believe on CC3200) 1) The delay interval is erratic, appearently because delayMicroseconds does not handle rollovers of the systick counter correctly. 2) delayMicroseconds can not work for dealys longer that 10,000 microseconds. (Even though the documentation says that it works up to 16383, and even includes an example.) Details: Issue 1) Code to demonstrate problem: #define DELAY_FOR 5000 void setup() { Serial.begin(9600); Serial.print("Delay"); Serial.println(DELAY_FOR); Serial.print("elapsed tics should be: "); Serial.println(F_CPU/1000000); } void loop() { unsigned long i = micros(); unsigned long systicstart = HWREG(NVIC_ST_CURRENT); delayMicroseconds(DELAY_FOR); unsigned long systicstop = HWREG(NVIC_ST_CURRENT); unsigned long p = micros(); unsigned long o = p-i; Serial.print("Before: "); Serial.print(i); Serial.print(" Systic: "); Serial.println(systicstart, HEX); Serial.print("After: "); Serial.print(p); Serial.print(" Systic: "); Serial.println(systicstop, HEX); Serial.print("After-Before: "); Serial.print(o); Serial.print(" Systic: "); Serial.println(systicstart - systicstop, HEX); Serial.print("Error: "); Serial.print(((long int)DELAY_FOR) - ((long int)o)); Serial.print("\t Systic: "); Serial.println((long int)((systicstart - systicstop) & 0xFFFFFF)-((long int)(F_CPU/1000000))); Serial.println(); } Just loops forever doing a delay, then printing how long the delay took (prints both in micros(), and ticks of the systick counter. (Note that micros() does not use the systick timer.) Example output: Before: 8470600 Systic: B5751 After: 8475601 Systic: 53C94 After-Before: 5001 Systic: 61ABD Error: -1 Systic: 399981 Before: 8599763 Systic: 2735 After: 8599893 Systic: C33E4 After-Before: 130 Systic: FFF3F351 Error: 4870 Systic: 15987457 Before: 8734135 Systic: 7055D After: 8739137 Systic: EAA0 After-Before: 5002 Systic: 61ABD Error: -2 Systic: 399981 While usually the delay is about 5000 microseconds, often it isn't (in the middle reading above the delay is much too short). The code from wiring.c (this is for Tiva, the CC3200 code is somewhat similar). void delayMicroseconds(unsigned int us) { volatile unsigned long elapsedTime; unsigned long startTime = HWREG(NVIC_ST_CURRENT); do{ elapsedTime = startTime-(HWREG(NVIC_ST_CURRENT) & 0x00FFFFFF); } while(elapsedTime <= us * (F_CPU/1000000)); } There are a few suspect things about this code: Since it is subtracting unsigned values, it seems to be the intention to rely on modular arithmatic to get the comparisons right. (As in discussed in this page http://www.thetaeng.com/TimerWrap.htm ). However as I understand it, for that to work the timer needs to overflow at the full width of the values being stored. In this case the timer is at most a 24 bit timer, but the values are 32 bits. If the full timer was being used, it might be possible to fix that by masking off the top 8 bits. elapsedTime = (startTime-HWREG(NVIC_ST_CURRENT)) & 0x00FFFFFF; However in this case the full width of the timer is not being used, it wraps to F_CPU/SYSTICKHZ after reaching 0 (it is a count down timer). So it looks like every time the systick timer rolls over, any delayMicroseconds which is in progress will have an unexpected result. (In the above output, where the delay was short, not the starting the starting value of NVIC_ST_CURRENT is small, and the ending value is close to C3500, which is F_CPU/SYSTICKHZ on a Tiva launchpad, i.e. the counter rolled over). Small side issue: The code also seems to assume that the upper 8 bits of NVIC_ST_CURRENT will always be 0 (the manual warns against making assumptions about such bits). A fix for that would be to add & 0x00FFFFFF to where startTime is set. I do not have a particular suggestion of how to fix the code. I think this issue also applies to the CC3200 (just from looking at the source code, but I have not checked that out in detail, and I do not have one to test.) -- 2) Since the systick counter rolls over every 10000 microseconds, delayMicroseconds can not delay for longer than that. .../energia-0101E0013/reference/DelayMicroseconds.html The documentation says "Currently, the largest value that will produce an accurate delay is 16383." (There is also an example which uses delays of this length.) The documentation may be a holdover from Arduino, which says the same thing, even though it does not appear to apply to the Arduino Due, for instance. (I do not know if this was true of MSP430.) A possible fix for the delay duration issue would be to add something like the following to the beginning of delayMicroseconds if (us > 9000){ delay( us / 1000); us = us % 1000; }; (the 9000 was somewhat arbitrary, rather than a constant it should be calculated based on SYSTICKHZ ). Might also be well to clarify the documentation about which platform the 16383 relates to. This is all on Energia 13, but I believe was also present in Energia 12.
  24. Hi All, I just started using cc3200 launch pad. I could get a external LED blink from webserver running on cc3200. I used SimpleWebServerWifi example to achieve it. Now I wanted to power the launch pad using 2 AA batteries. I could power it as per instructions, but it is not lasting more than 1 hour. Can someone tell me how to enable power saving mode? I want to wakeup only GPIO pins after webserver receives any request. Please help me. Thanks Venu
