[Ralph Doncaster], aka Nerdralph, seems to be absolutely driven to see how few resources he can use on a microcontroller to get the job done. In this post on his blog, [Ralph] writes some custom ...

In order to implement it to your MCU of choice, you need to manipulate functions inside nrf24l01_low_level.c file (SPI, pin configurations) and leave other files as they are. nRF24L01+ C library ...

#define SS_R_LOW (PORTD.OUTCLR=SPI_SS_R) #define SS_R_HIGH (SPI_PORT.OUTSET=SPI_SS_R) #define SS_T_LOW (PORTA.OUTCLR=SPI_SS_T) #define SS_T_HIGH (PORTA.OUTSET=SPI_SS ...

Wireless data transmission enables many applications (e.g., in the field of home automation). However, the communication must be robust and reliable. This nRF24L01+-based PIR sensor project is a basic ...

[Necromant] wrote a library to flash his microcontroller over an RF link using an NRF24L01 wireless communication module. The NRF24L01 is a cheap RF module that can be easily integrated into many ...
