    MSP430FR2355 problem to connect with nRF24L01+

    Sorry for the late reply, yes it works very well with this new file, But there is only one available SPI on Energia , USCI B1: - MOSI = P4.6 - MISO = P4.7 - CLK = P4.5 #include <SPI.h> #include <Enrf24.h> #include <nRF24L01.h> #include <string.h> Enrf24 radio(P5_0, P1_4, P2_2); //WIRING MSP430FR2355 P5_0=CE, P1_4=CSN, P2_2=IRQ -> MOSI P4.6, MISO P4.7, SCK P4.5 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 ); // Defaults 1Mbps, channel 0, max TX power radio.setCRC( 1, 1 ); 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); } Thanks you !!!
  2. 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 !
