Hi,
I was wondering if someone has available library and example code, to use for sending and receiving data using MikroBasic Pro for ARM, STM32F415 and nRF24L01.
Thanks

Hey,
My problème is the uart don't give correct information with the lib of mickoe C and the serial monitor.
For exemple i put the character A but the monitor detect lot of information....

Communication > CAN / LIN / RS485
Need example code for using MCP2518FD
any language
register setup
transmitting and receiving
