I have the nRF24l01 library for Arduino. I am trying to write my own code, but that's hard when you don't know how the library's functions work. So I was wondering if someone could give me a link to how to use the functions, or tell me how to use the common ones like the .read() and .write() functions. For example:
unsigned long time = millis(); printf("Now sending %lu...",time); bool ok = radio.write( &time, sizeof(unsigned long) );
I'm sure this is a common c+ thing, but why is there "&" in front of "time" and, if I can, how do I send and receive Strings?
Thanks for any help!
