  1. Hi All, I want to use a library which is made for Arduino. But Im having problems when Im trying to compile by using Energia. The First problem is ADC settings bvsm.setAudioInput(BVSM_AUDIO_INPUT, EXTERNAL); There is no EXTERNAL adc reference, How Can I correct this issue? ISR(TIMER2_COMPA_vect) { if (globalBVSMic != NULL && globalBVSMic->isRecording) { //Starts ADC conversion sbi(ADCSRA, ADSC); } } And in this part I get errors, I think I should change the value of ISR which is "TIMER2_COMPA_vect" to something suitable for CC3200, but I couldnt find anything. Can you help me please, I also attach the libraries that I try to use. BVSMic.cpp BVSMic.h
  2. Hello, I have been trying to make the SimpleWebServerWifi example in Energia to work for the past few days. The program is able to compile and upload to the board no problem and I have the most current servicepack installed on the MCU and have the most current Energia IDE installed. The problem I am having is the MCU gets stuck at the line "Wifi.beign(ssid, password)". I have tried connecting to my home router, my phone's hotspot, and also I made my phone's hotspot identical to the example settings so I did not have to change anything in the example to reduce mistakes. (Please find attached the settings I used for the hotspot). When I first go the MCU about a year ago it worked out of the box and I got the Lab0 to work and also wlanstation to work in Code Composer Studio. If anyone has any suggestions on what else I could try they would be greatly appreciated! Thanks in advance, Sheldon

  4. Hello, In the case there's no internet and I'm trying to connect to a TCP Server on the CC3200 using the following statement tcp.connect(remote_ip, remote_port) // WiFiClient.connect My program hangs for 30 SECONDS on the above statement. Is there a library file where I can reduce this timeout to something more reasonable like 5 seconds? Thanks!
  5. Hi there, Really excited to see the new release of Energia supporting the CC3200 launchpad! I just ordered some for myself. Does anyone know if there are plans to include the SSL demo for the CC3200 in Energia? Thank you!
  6. Hi, I am using MQTT client on CC3200 with Energia. Case1=> When CC3200 is connected to wifi router and there is Internet connection on the router, I received data on MQTT and there was no delay in connection of either tcp or mqtt client. Case2=> This case is valid only when CC3200 is connected to the router but there is no Internet on it. Now the issue is that as cc3200 is connected to the router with no Internet, it will try again and again to establish MQTT connection. But when it tries to establish tcp client connection it takes 28 seconds and when return code from tcp arrives only then the rest of the code resumes to work. It hangs in that part. Is there any way to reduce this time by changing any parameter in the library? I found one constructor in MQTTclient.h library. Client(Network& network, unsigned int command_timeout_ms =30000); I changed the command timeout value by different ones but no change was observed. It was still taking 28 seconds. After that tcp return code came as 0 which indicated that tcp connection was not made. I would like to ask that is there any way to reduce this time. Like can the time it is waiting for return code be changed.Can it be made less? Please reply asap. Waiting for your guidance robertinant@yahoo.com.
  7. Hi, I am currently working on a code in Energia that will allow me to upload and send a binary file wirelessly from a client site to the CC3200. So far, the code has successfully accomplished the following: -the board establishes a Wi-Fi network -commands from a laptop can interact with the board (the Energia Simple Wi-Fi Server example (LED ON/OFF) code was tested to ensure this was working) -a 9 byte binary file is sent through Wi-Fi to the board's volatile memory, saved from volatile memory into an on-baord flash memory file, and confirmed by sending it back to the laptop through a serial connection The code is eventually supposed to receive a larger binary file (we hope around 500 KB) that will represent points on a sinusoidal curve. This file will then be sent to the Audio Booster Pack board to play the audio file. I created a flash file which was opened, and written to through a buffer array containing the binary file contents. This method was successful for a 9 byte file, but I learned that a larger 500 KB file cannot be stored in a buffer array so easily. I think this is because of a lack of RAM space on the board. How can I implement a code in Energia in order save this larger binary file to the flash memory? Is the buffer array approach a good method? Latency isn't really an issue, as long as we can fit the whole file on the board, and then play it after. Thanks, any support is greatly appreciated!
  8. Hi, I am using CC 3200 in ap mode first then when I feed the cc3200 with ssid and password it starts its STA mode. But sometimes cc3200 hangs when shifting from ap 2 sta mode. And when the reset button is pressed my cc3200 connects to ssid that i sent. Why is that happening? Is there any way by which I can do a software reset? I know about the watchdog timer but how to use it in this case.

  10. Hello, If I use Energia IDE with CC3200 then Is Energia can support CC3200 APIs during programming? If Yes, then in which language programming I do in Energia with APIs? Regards, Pratik
  11. Hello! I recently started playing with Energia and the CC3200 LaunchPad. I tried the example for "attachInterrupt" in the link: http://energia.nu/reference/attachinterrupt/ I changed the code a little by modifying pinMode and attachIntterrupt #define PUSH 4 ... pinMode(PUSH, INPUT); // I want Pin 4 as my interrupt or SW3 on the board, only Input because the board has a pull down resistor already attachInterrupt(PUSH, blink, FALLING); } void loop() { ... } When I run this example, the interrupt is serviced multiple times at random without me touching the button. I wanted to know if anybody else has encountered the same problem or could someone try it and let me know if the interrupt works for them? I'm not sure what I'm doing wrong. Any advice is welcomed! Thank You!

  13. I put together a prototype Booster Pack that attaches to the CC3200 and has a RFID-RC522 card (sometimes called a MIFARE module), two buttons, and two LEDs. The CC3200 is connected to the cloud using Temboo. Currently it sends an email to me with information on the card used when accessed but it would be easy to modify to record time of access, card used, etc and put it into say a spreadsheet. This was a one afternoon plus an evening project for both hardware and software using Energia - very easy to do. The cards have security holes but I am pretty sure they pose too high a technical challenge for my local hooligans. I'm more afraid they might rip it apart and take my CC3200 than anything else. This is the Booster Pack, top view. Here it is attached to an upside down CC3200. In this photo it has been mounted in an enclosure and is reporting a successful read and transmission with the green LED. And if you are really interested, here is the schematic. I am using the RFID library located here. And if you aren't familiar with Temboo, find it here.

  16. Hi all, How to run MQTT server on cc3200 from energia. Is there any libarary to do so?
  17. Hi all, how to run os mode(multiple threads) on cc3200 from energia.
  18. Hello Everyone, I am planning on building an IoT robotic snow plow using a CC3200 Launchpad. Does anyone have suggestions on what camera module to use with the CC3200?
  19. Hi, I am working on a project that reads the values from the weighing machine and the data is then sent to cc3200 web server from where a client can access the data. For dynamic change of data on web page i am refreshing the page at 0.5 seconds.Everything is working as expected. Now the new requirement is that a user has to enter some predefined value on web page and after that the further calculation is to be done. I am unable to do so.How to Enter any value on web page and then obtain that value in my code and then do further processing.
  20. I have a project using an MLX90614 that I have prototyped on an Arduino. Now I want to move to the CC3200 to add WiFi support. I've been fighting with the I2C for a few days now and could use some help. A few notes: The built-in I2C sensors (BMA222 and TMP006) work fine in the default configuration. The max speed for the MLX90614 is 100 KHz, but the default for the CC3200 is 400 KHz The MLX90614 is technically SMBus, but it works flawlessly with the Wire library on a standard Arduino. I have modified the Wire library in the hardware/cc3200 folder to call MAP_I2CMasterInitExpClk(I2C_BASE, F_CPU, false) instead of MAP_I2CMasterInitExpClk(I2C_BASE, F_CPU, true). According to the code in driverlib/i2c.c, this should cause the bus to run at 100 KHz. This change does not make the MLX90614 work, but it does cause the other two sensors (BMA222 and TMP006) stop functioning properly. (The TMP006 fails to be recognized, and the BMA222 returns incorrect data - x, y, and z all seem to show the x value or the y value... not sure which.) After searching the web and this forum, this I've gotten this far but now run into a dead end. Does anybody have experience with I2C on the CC3200 with Energia and a slower-speed bus? I'd like to avoid rewriting my project in CCS if possible. Thanks much! -Nathan
  21. I am using the SimpleWebServerWiFi example in Energia as a basis for my application, which has become a bit large. My trouble is, sometimes the update of the client web page requested is fast, while sometimes it is painfully slow without changing any code. There is only one web page. I have no idea where to start looking, is there any clues out there what can cause the web server of the cc3200 working slow? For example, if the output it is slow, hitting a button on the client web page, causes the server to fast reload the same page. regards,
  22. Hello. New here and having trouble getting my Mac Mini (10.12) to recognise the 3200 LauchpadXL. Other non-TI boards and FTDI adaptors show up fine in Arduino/Energia. Anybody got experience of why the port would not show? No obvious devices are showing in /dev Many thanks.
  23. Hi, I'm working on some of the project where I have to communicate CC3200 to external microcontroller (CC2650) using UART communication .Is the serial pass through or serial event example can work on CC 3200 to communicate with ex. microcontroller? I'm new to energia. Awaiting for your response on the same. Thanks & Regards, Shashank
  24. Dear All, I would appreciate some help from you here. I am using Energia v0101E0014 (v15) The uploaded picture shown my 3200LP jumper setting. The 3200LP is using SPI to talk to Cypress CY5FRAMKIT (http://www.cypress.com/?docID=52945) The Cypress kit is using its default 5V setting on jumper J5. So I connect P3.1 (5V) to feed the Cypress power. My Wiring for cc3200 is as below CC3200 Signal Name ---- ------- P1.7 SCLK P2.3 CS P2.6 MOSI P2.7 MISO P2.1 GND P3.1 5V However I can't read/write data to it. I was able to use the same kit in Arduino platform, so the kit is good. Q1: DO I need to anything special to the CC3200 default jumper setting in order to use the above SPI pin iterface? Q2: What is the CS pin number in Energia code if I use P2.3 as the CS ping? Is it number "8", "18" or ... ? Thanks in advance.
  25. Hi, During the last two days I wanted to give Energia a try for performance testing of CC3200 based modules. On first glance TCP/IP performance is better than ESP8266 but I stumbled over many issues and currently I don't know whom to ask for: Energia, TI, RedBearLabs, ... I faced the same issues with either TIs original CC3200 Launchpad XL and RedBearLabs Wifi Mini module. Even if you only have comments, thoughts or solutions for a single one of my issues, please post your answer and reference to the issues numbered below. (1) First I was able to run the OutOfBox and blink examples. Then after playing with my own skript using AP and station mode as well as fixed and dynamic IPs somehow the DHCP server was not working any more. I tried the OutOfBox example, and again no IPs were provided to the clients. It seems that the CC3200 module stores information in a place which is not overwritten by Energia when uploading new code but used by the underlying TCP/IP stack. After hours of experimenting I decided to format the flash with TIs UniFlash tool, and to install the newest service pack, and surprise, instantly the DHCP service was functional again. Question: What happend there, and how to prevent that in future? I cannot risk that the module gets unusable after selling to a customer! (2) Since the reformatting of the flash open APs do not work any more. It doesn't matter if I use WiFi.beginNetwork(ssid, "00000000") or WiFi.beginNetwork(ssid). The network in both cases is created in WPA2 mode requiring the password "00000000". I think but have no proof for that it was working before the re-flashing procedure... Question: How to create open AP again? Only guessing, but is it a problem of the current service pack? (3) If I use WiFi.config(apIP, apDNS, apGateway, apNetMask) before calling WiFi.beginNetwork() then the IP of the AP is changed as expected, e.g. to 192.168.5.1 but the DHCP remains in it old range, so the client gets 192.168.1.2 and can never reach the webserver at 192.168.5.1 (as it is running in another net). Question: How to change DHCP behaviour from Energia, and why is it not done automatically based on IP of AP? (4) The worst issue is related to the following line of code which I use in a loop for TCP/IP performance tests: currentTransferSizeReport = client.write(fileDownloadBuffer, currentTransferSize); If I increase the currentTransferSize up to 1460 bytes everything is working fine, transmission throughput increases as expected. If I go beyond 1460 then transmission throughput decreases, and on first glance everything looks right, but the receiver gets more data than transmitted! I tested my simulated file download with various browsers, and if I transmit exactly 100MByte these 100MByte appear in the browsers download folder only when using a block transfer size of <= 1460 bytes. In case of using larger sizes the received data file is larger, but not constant, I got up to 114 MBytes! So from my point of view it looks like a problem in the TCP/IP stack somehow related to transfer size and window size. My problem is that the transmission looks error-free (the server sees that the reported transfer size matches the requested one) but it is not. My cheap ESP8266 module currently reaches half the speed of the TI module but at least it transmits the data untouched! Question: What happens there, and how can I determine which transfer size to use to get my data transported safely without corruption if no errors are reported? (5) The String class constructor using a float value as input is not functional, it always delivers 0.000. From my point of view the dtostrf funtion is used, which tries to use sprintf, which is not implemented for floats within the Arduino source code for performance reasons. Question: Does it only happen on my system, so someting went wrong during Energia installation? I can hardly believe that such a basic function is not working (so has never been tested)? (6) After downloading code from Energia to RedBearLabs Wifi Mini module it got 4 quite similar error messages, the first one is DEBUG cc3200prog.c:2667: write failed However, the code has successfully been downloaded but not started, I have to press the reset button manually after downloading. These error messages do not appear when downloading code to TIs Launchpad. Whew, that's all for the moment. With best regards, Kelrob
