Master (transmitter) example of using nRF24L01 with STM32F407VET6.
Master (transmitter) example of using nRF24L01 with STM32F407VET6 black boards.
Connect (plug in) the nRF24L01 module to the NRF24L01 connector located on the STM32F407VET6 board as follows:
nRF24L01 | STM32F407VET6 |
---|---|
Vcc | +3.3V |
GND | GND |
MOSI | PB_5 (SPI1 MOSI) |
MISO | PB_4 (SPI1 MISO) |
SCK | PB_3 (SPI1 SCK) |
CSN | PB_7 (CS) |
CE | PB_6 (CE) |
