The source code of RC2 of my port GHI Electronics TinyCLR-0SV2RC1 nRF24L01 library is live on GitHub. The sample application now supports Fezduino (with embeddedcoolness.com or other Arduino shield), Fezportal and the SC2010 Dev board (with mikroe nrf24C Click, mikroe nRF24S Click or mikroenRF24T Click) .
The application has gained four compile time configuration options
- TINYCLR_V2_SC20100DEV_MIKROBUS_1
- TINYCLR_V2_SC20100DEV_MIKROBUS_2
- TINYCLR_V2_FEZDUINO
- TINYCLR_V2_FEZPORTAL
These options configure the chip enable, chip selected and interrupt pins.
