  1. Hello there, Ive been trying to use the UART on pin number 3 and 4 by using serial for monitoring the received data and serial1 for connecting and controlling the hardware(GPS) but the by using serial1 i think the uart isnt active. i see by connecting gps to putty that there is no data sent from the cc device . I checked the hardware serial .h and .cpp file where in the cpp file there is serial1 functions mentioned but in the pins_energia file i see no pin initialized as uart only analog, timers and gpio's are initialized. So what can i do to make it work. 1 2 3 4 5 6 7 8 9 10 11 12 13 Serial1.begin(112500); Serial.begin(19200); delay(50); Serial1.println("AT"); delay(1000); Serial1.println("AT+QGNSSC?"); delay(1000); Serial1.println("AT+QGNSSC=1"); delay(1000); Serial1.println("AT+QGNSSTS?"); delay(1000);
  2. Hello,. My idea is about connecting two CC3200 without a separate WiFi router like with their own like for example share it app which connects two devices using wifi one device with hotspot and one connected to that hotspot and share data.Is it possible to do that? As my idea is to share short text data between devices. using energia I want to continuously send/receive data between 2 cc3200 without any other modem unit or with another cc3200 which will be an access point between 2 of them. Is this possible ? If so , where should i begin? cc3200 (unit a) <-------> cc3200 (unit b) or cc3200 (unit a) <------via cc3200 (as AP) -------> cc3200 (unit b) Thank you

  8. Hello there, I connected a gps module and it gives me the gps data but im unable to segregate the following data on energia +QGNSSRD: $GNRMC,044927.000,A,1301.7816,N,07731.3016,E,0.00,93.73,290319,,,A*4F so i need to separate the latitude and longitude, time and date. So can anybody help me in understanding how to get the required data from the above. i attached my code below as you can see im getting stuck in the serial read please help me in correcting this. ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 char gps; int times = 1; int count = 0; void setup() { Serial.begin(115200); delay(2000); Serial.println("AT"); delay(1000); //Serial.println("AT+CMGF=1"); Serial.println("AT+QGNSSC?"); delay(1000); Serial.println("AT+QGNSSC=1"); delay(1000); Serial.println("AT+QGNSSTS?"); delay(1000); } void loop() { while(count < times) { Serial.write("AT+QGNSSRD=\"NMEA/RMC\""); delay(2000); if(Serial.available() >0) { gps=Serial.read(); String response = ""; response +=gps; Serial.println(response); return response; } count++; } }
  9. Hi, Does anybody have an idea of when will energia ide support Hercules TMS570LS04x/03x LaunchPad is gonna release? Can we add that board to energia? If yes, can anybody suggest in how to add a new board to energia so that i shall try adding it. Thanks

    MSP430FR6989 pins_energia file

    Hi there, I've seen that the pins_energia file for MSP430FR6989 is designed for launchpad itself. So i,m developing a custom board using MSP430FR6989 will that same pin out file with the launchpad pin numbers can be used, or is there any pins_energia file only for that IC with all the pin numbers for each pin, or should i modify it accordingly?, if needed to modify then what changes can i do to make it compatible please help. Thank you
  12. Hi, Iam planning to make a project which involves GPS and GSM ive decided to use the Quectel MC60 for this purpose. Can anyone here guide me on how to do this like the libraries required references, example codes . Thanks
  13. Hi, Can anyone provide me the links or code for basic read and write example on FRAM of MSP430FR6989 on energia?

  15. Hello, Im getting an error while compiling the 128x64 LCD u8g2 library on msp430fr6989. I tried the hello world code on it full buffer. I complied the same code on msp432p401r it compiled and even the display worked but the same code when changed the board to FR6989 its says fatal error assert.h no such file or directory, the screen shot is attached below. Please help me with it. Thank you U8g2_Arduino-master.zip
  16. Hello there, I have 128x64 graphical dot matrix display lying around with the driver ST7567, so ive been thinking can i interface it with msp432 or 430? i found a library for arduino in github but when i added the library to energia and compiled it i get the following error attached below. I have attached the library and the screen shots below, in that library there are for many lcd controllers i selected " U8G2_ST7567_JLX12864_F_4W_SW_SPI" it worked out fine on arduino. can any one help me out??

    MSP432P401R SD card interface

    hello there, Ive been trying trying to interface an sd card to msp432p401r but i get many errors. my task is top build a data logger where the sensor readings will be stored in a text file. So i tried basics first. First i tired to serial print the sd card info but had lot of errors (screenshot can be seen below). the files i used is attached in the rar file "SD", in that i tried the Card info example. Please can someone help me what is wrong with this code. Thanks SD.rar

    MSP432P401R SD card interface

    I use a Sandisk ultra SDHC 16Gb . No i did not try different cards. And the SPI bus isnt shared with any other devices

    MSP432P401R SD card interface

    I tried the same code and the same SD card with Arduino uno, the card was detected. So what might be the possible reasons for not getting detected with MSP432P401R ??, even though the connections are right.

    MSP432P401R SD card interface

    Thank you for your reply. @terjeio Can you please provide me the link of SD card example on the TI SDK. And it would be helpful if you can tell me the pin configuration with the msp432p401r . Will give it a try using CCS and see is it the same or not.
