  1. yea yea ok thank you for your reply
  2. Thank you for you reply. Yes please do contact.
  3. hello, Im trying to interface a 2 inch rgb LCD display with ST7789v lcd driver im using the ucglib library for this i get a few errors stating not been declared need assistance with this please. I attached the library used and the screen shot. ucglib-master_editted.zip
  4. 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);
  5. 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++; } }
  6. 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
  9. 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

    MSP430FR6989 FRAM example code for energia

    Thanks @Rei Vilo
  11. Hi, Can anyone provide me the links or code for basic read and write example on FRAM of MSP430FR6989 on energia?
  12. 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

    128x64 Graphical lcd display interface with MSP432 or 430

    Thank you for the reply. it helped a lot
  14. 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??
