Hello I have problems with the two NRF24L01 and two tm4c123gxl. I can not get it running. Pins 1. Tm4c123gxl (RX): PC_6 (CE), PD_2 (MISO), PD_3 (MOSI), PD_1 (CS), PD_0 (SCK), PE_1 (IRQ) Pins 2. Tm4c123gxl (TX): PC_7 (CE), PD_2 (MISO), PD_3 (MOSI), PD_1 (CS), PD_0 (SCK), PE_1 (IRQ) I will use a simply Sketch. I have found this in the Forum [Energia Library] Nordic nRF24L01+ library I have download this Enrf24_v1_8.zip from the Forum. Enerf24_RXdemo #include <Enrf24.h> #include <nRF24L01.h> #include <string.h> #include <SPI.h> Enrf24 radio(PC_6, PD_1, PE_1); const uint8_t rxaddr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0x01 }; const char *str_on = "ON"; const char *str_off = "OFF"; void dump_radio_status_to_serialport(uint8_t); void setup() { Serial.begin(9600); SPI.begin(); SPI.setDataMode(SPI_MODE0); SPI.setBitOrder(MSBFIRST); radio.begin(); // Defaults 1Mbps, channel 0, max TX power dump_radio_status_to_serialport(radio.radioState()); radio.setRXaddress((void*)rxaddr); radio.enableRX(); // Start listening } void loop() { char inbuf[33]; dump_radio_status_to_serialport(radio.radioState()); // Should show Receive Mode while (!radio.available(true)) ; if (radio.read(inbuf)) { Serial.print("Received packet: "); Serial.println(inbuf); if (!strcmp(inbuf, str_on)) Serial.println("HIGH"); if (!strcmp(inbuf, str_off)) Serial.println("LOW"); } } void dump_radio_status_to_serialport(uint8_t status) { Serial.print("Enrf24 radio transceiver status: "); switch (status) { case ENRF24_STATE_NOTPRESENT: Serial.println("NO TRANSCEIVER PRESENT"); break; case ENRF24_STATE_DEEPSLEEP: Serial.println("DEEP SLEEP <1uA power consumption"); break; case ENRF24_STATE_IDLE: Serial.println("IDLE module powered up w/ oscillators running"); break; case ENRF24_STATE_PTX: Serial.println("Actively Transmitting"); break; case ENRF24_STATE_PRX: Serial.println("Receive Mode"); break; default: Serial.println("UNKNOWN STATUS CODE"); } } Enrf24_TXdemo #include <Enrf24.h> #include <nRF24L01.h> #include <string.h> #include <SPI.h> Enrf24 radio(PC_7, PD_1, PE_1); // CE, CSN, IRQ const uint8_t txaddr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0x01 }; const char *str_on = "ON"; const char *str_off = "OFF"; void dump_radio_status_to_serialport(uint8_t); void setup() { Serial.begin(9600); SPI.begin(); SPI.setDataMode(SPI_MODE0); SPI.setBitOrder(MSBFIRST); radio.begin(); // Defaults 1Mbps, channel 0, max TX power dump_radio_status_to_serialport(radio.radioState()); radio.setTXaddress((void*)txaddr); } void loop() { Serial.print("Sending packet: "); Serial.println(str_on); radio.print(str_on); radio.flush(); // Force transmit (don't wait for any more data) dump_radio_status_to_serialport(radio.radioState()); // Should report IDLE delay(1000); Serial.print("Sending packet: "); Serial.println(str_off); radio.print(str_off); radio.flush(); // dump_radio_status_to_serialport(radio.radioState()); // Should report IDLE delay(1000); } void dump_radio_status_to_serialport(uint8_t status) { Serial.print("Enrf24 radio transceiver status: "); switch (status) { case ENRF24_STATE_NOTPRESENT: Serial.println("NO TRANSCEIVER PRESENT"); break; case ENRF24_STATE_DEEPSLEEP: Serial.println("DEEP SLEEP <1uA power consumption"); break; case ENRF24_STATE_IDLE: Serial.println("IDLE module powered up w/ oscillators running"); break; case ENRF24_STATE_PTX: Serial.println("Actively Transmitting"); break; case ENRF24_STATE_PRX: Serial.println("Receive Mode"); break; default: Serial.println("UNKNOWN STATUS CODE"); } } When i am upload this, i don't see the Sending objects. I see only in both Serial.monitor this: "Enrf24 radio transceiver status NO TRANSCEIVER PRESENT". Can someone help me?
