  1. Hi, I'm implementing an application for CC3200MOD in Energia 1.6.10E18 environment in which host MCU (Atmel AT76C114) sends jpeg image data (size varies from 1MB to 3MB) over SPI to CC3200MOD which then sends it over WiFi to PC. So Atmel acts as SPI master and CC3200MOD SPI slave. The bottleneck is SPI receive rate in CC3200MOD end. I need to configure host MCU SPI clock to 10.5MHz in order to receive correct data on CC3200MOD. With higher clock rate the data gets corrupted. When receiving valid data the transfer rate is 0.17 MBps. This is way too low for our purposes. I have understood that by using SPI DMA one could receive higher transfer rate. Are there any SPI DMA examples available for SPI slave receive in Energia environment? Does SPI DMA work on SPI slave when SPI master sends data continuously or does it require changes also for the sending procedure from SPI master? Thanks, Yuzzie
  2. Hi there Currently I am using the Serial1 pin to I2C for the LCD. so, I can't use the Serial1 in the CC3200EMT (multitasking).When I see the source code of Board_init.c, there is Board_openUART() function which seems to initiate the PIN. I need to change the pin 3 and 4 to 7 and 8. but even I changed the source code, it wasn't able to apply them. It seems the complier linking the binaries directly. Did you already announce the procedure how to recreate libraries? or Can you suggest other ways? //MAP_PinTypeUART(PIN_03, PIN_MODE_7); MAP_PinTypeUART(PIN_07, PIN_MODE_5); //MAP_PinTypeUART(PIN_04, PIN_MODE_7); MAP_PinTypeUART(PIN_08, PIN_MODE_5);
  3. Hi Experts I'm using cc3200 MOD and currently using GPIO pin "P01 and P02" as UART modul I know cc3200 has two UART modules - one can be from P01andP02 and other is from P55 and P57. I have a requirement whare I need to retain UART0 and URAT1 for two different use case - one fore display and other to transmit data. I'm using Energia for coding and new to this pinmux etc., Question: from where I need to do the configuration? Should I need to update my INO file? if so with what? can you please help! appreciate your time. Regards,
  4. I've been searching for the Wi-Fi SensorTag firmware. Has anyone see it on TI's wiki or tool site? I just received mine. It works seamlessly, but I wanted to play around with the firmware a little.
  5. I have a CC3200 Launchpad with pre production silicon - CC3200HZ. Launchpad hardware version is 3.2. I've upgraded my PC and this Launchpad takes in older SDK and service pack versions. I don't have time to install and test it. The CC3200 will ship formatted. This helpful member, @Arkham00 has listed out compatible versions of the CC3200 SDK and Service Pack.

  6. Hello chaps! What I'm basically trying to do is record as much audio as I can (about 30k samples from a line-in source) then dump it all over serial. I'd like to use the Audio Booster pack (http://www.ti.com/tool/cc3200audboost) which does all the codec magic for me. But - I can't get it to work with energia. (to be honest, the documentation for how to actually use the thing is pretty poor regardless of programming tool...) I did my best to duplicate the needed parts of the (also terrible) Wifi audio demo app from TI's official SDK but to no avail. Has anyone had success at getting audio off this thing? Thanks!
  7. Hi, I am using CC3200 LaunchXL for configuring LORA semtech 1272 over SPI Driver. I searched a lot example or reference for cc3200 for transmitting message using SPI but unable to get for Energia IDE. I have code for Arduino Lora implementation but unable to run it on Energia. Kindly help me as soon as possible Thanks and regards Rohit
  8. 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
  9. 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

  11. 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!
  12. 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!
  13. 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.
  14. 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!
  15. 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.

  17. 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
  18. 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!

  20. 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.
