Hi I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using RF24.h library. I am not using Arduino.
The transmitter chip is transmitting a single byte data, however the receiver is not being able to receive the data. Although the carrier detect flag on the receiver side goes high each time the transmitter transmits. I am not using any library and also I have disabled the auto acknowledgement feature.
Here is the sequence on the receiver:
CE_Write(0);
SPIM_1_PutArray(PowerUp, 2); CyDelay(40); // Power up, disable CRC and set as PRX
SPIM_1_PutArray(PowerUp, 2); CyDelay(40); // Power up, disable CRC and set as PRX
SPIM_1_PutArray(Set_Feature, 2); CyDelay(40); // Set feature for enabling W_TX_PAYLOAD_NOACK
SPIM_1_PutArray(AA_Feature, 2); CyDelay(40); // Activate features
SPIM_1_PutArray(RX_PW_P0, 2); CyDelay(40); // Set payload width for pipe 0 to 1 byte
SPIM_1_PutArray(AW, 2); CyDelay(40); // Specify Address width to 3 bytes
SPIM_1_PutArray(TX_ADD, 4); CyDelay(80); // Transmitter address
SPIM_1_PutArray(RX_ADR_PO, 4); CyDelay(80); // Receiver address on pipe 0
SPIM_1_PutArray(EN_AA_P0, 2); CyDelay(80); // Disable auto caknowledgement on all pipes
SPIM_1_PutArray(RF_CH, 2); CyDelay(80); // Set RF channel to ch 1
SPIM_1_PutArray(E_RX_ADD, 2); CyDelay(80); // Enable pipe 0 for receiving
SPIM_1_PutArray(RF_SETUP, 2); CyDelay(80); // Air data rate = 1Mbps, RF Power = 0db
CE_Write(1); SPIM_1_PutArray(R_RX, 2); rx = SPIM_1_ReadRxData(); rx = SPIM_1_ReadRxData();
What am I missing? Please tell me a basic code code to transmit and receive a single byte data without using any dedicated library. I will be very very very thankful!
Thanks in advance!
