  1. Hello, I'm trying to set up the backchannel UART on the MSP430FR2355 launchpad so that it echoes back the characters I send it. I believe I've configured the UART on the msp430 correctly for 4800 baud. Please see the attached main.c.main.c.4800 When I try to send characters after opening a UART connection, I just see question marks. I'm stumped. I'm using mspgcc, mspdebug, and linux for what it's worth.
  2. Hi, I'm new here and I just started programming the TI MSP430FR2355. I have been struggling to get any examples of code I've found online for the use of Timer A to compile in CCS Studio, it always says everything related to Timer A is undefined. I just found this location on the TI website: http://dev.ti.com/tirex/explore/node?node=ANzAuV9QdJf4FZucFqNrMA__IOGqZri__LATEST I tried the code there to set up Timer B and it works!!! I notice there are no examples whatsoever on this page that use Timer A, but in all the documentation I have found Timer A is a thing on the FR2355... so what am I missing? For example f I try to compile anything with "TACCR0" it will say it is undefined... but if I change it to "TBCCR0" it compiles just fine. I feel like I am losing my mind here. I have found absolutely nothing on the internet from anyone else saying they can't get Timer A to work, but they can get Timer B to work. Unfortunately there seems to be little information on programming the FR2355, other than the official TI documents, seems like everyone else is using some other kind of MSP430. Thanks in advance for any help.
  3. Hi, I recently bought a MSP-EXP430FR2355 launch pad to build a Weather station with NRF24L01+ so i have used a specific library Enrf24.h for ENERGIA. The code for below already works with my MSP-EXP430FR2433 but not with my new MSP-EXP430FR2355. I can't use the MSP430FR2433 beacause it doesn't have enough memory for me to add my temperature sensor BME280 with all code required by the sensor... On the other side i can receive the information ON and OFF with a Raspberry Pi send by the FR2433 but not with my FR2355. #include <SPI.h> #include <Enrf24.h> #include <nRF24L01.h> #include <string.h> Enrf24 radio(P1_3, P1_4, P2_2); //WIRING MSP430FR2355 P1_3=CE, P1_4=CSN, P2_2=IRQ -> MOSI P1.6, MISO P1.7, SCK P1.5 const uint8_t txaddr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0x01 }; const char *str_on = "ON65"; const char *str_off = "OFF65"; void setup() { Serial.begin(9600); Serial.println("RED10"); SPI.begin(); SPI.setDataMode(SPI_MODE0); SPI.setBitOrder(1); // MSB-first radio.begin( 1000000, 76 ); radio.setCRC( 1, 1 ); //radio.begin(); // Defaults 1Mbps, channel 0, max TX power radio.setSpeed(250000); radio.setTXaddress((void*)txaddr); // Serial.println("RED10"); Serial.print("STATE: "); Serial.println(radio.radioState()); Serial.print("SPEED: "); Serial.println(radio.getSpeed()); } void loop() { Serial.println("ON_1"); radio.print(str_on); radio.flush(); // Force transmit (don't wait for any more data) delay(1000); Serial.println("OFF_1"); radio.print(str_off); radio.flush(); // delay(1000); } With the MSP430FR2433 STATE: 1 and SPEED: 250000 which is ok With the MSP430FR2355 STATE: 0 and SPEED: 1000000 The code stops when we entrer the loop without communication i thinks it's the SPI but it can be the library itself Thanks for your help !
  4. Dear all I have bought a new msp430fr2355 launch pad. I was doing my setup coding test on that board using energia as a fast tool. I tried to blink the built in LED and works well.when i tried to use serial to print a string on terminal, nothing appear and sometimes freeze up the LED blinking. too, i tested the pins connection in the PCB (msp launch pad) and everything was fine. so what the problem with serial interface?!.Thanks in advance
