An Arduino port of the tinkerer.eu library. It works with most nRF24L01+ modules. http://www.arduino.cc/playground/InterfacingWithHardware/Nrf24L01 For the attiny, pls use the tiny cores below as they are many other tiny cores with different mappings to Arduino Digital pins. https://code.google.com/p/arduino-tiny/ For this fork, I include :- * SPI85 libs for attinyXX support * attiny84 examples codes working with RF24 * Rename SPI pin names to USI_DI / USI_DO * To set radio MAX power, use this code below :- Mirf.configRegister( RF_SETUP, ( 1<<2 | 1<<1 ) ); * If the RF24 receiver have dynamic payload enable, use this code :- Mirf.configRegister( FEATURE, 1<<EN_DPL ); Mirf.configRegister( DYNPD, 1<<DPL_P0 | 1<<DPL_P1 | 1<<DPL_P2 | 1<<DPL_P3 | 1<<DPL_P4 | 1<<DPL_P5 ); * If attiny used as a receiver from RF24 libs/devices, the RF24 libs config, pls disable Dynamic Payload as the Mirf does not "yet" support reading the dynamic payload size. Use static payload instead. * Blog entry on getting nRF24L01 working with attiny84 :- http://arduino-for-beginners.blogspot.com/2013/08/getting-nrf24l01-to-work-with-attiny84.html From xdarklight/arduino-nrf24l01 forks :- This fork includes the following changes: * Added support for the SPI85 library on ATtiny85 chips. * Compatible with ATmega and ATtiny chips (tested with ATtiny85). * Can connect to devices using the RF24 library by setting "Mirf.baseConfig = _BV(EN_CRC) | _BV(CRCO);" before calling "Mirf.config();". * Reduced binary size. Other information: * This library supports changing less popular registers without having to "hack" the libraries code. An example for changing the RF_SETUP register: "Mirf.configRegister(RF_SETUP, _BV(RF_DR_LOW));" Stanley email@example.com
