Collegamento dell’EByte E70 ai dispositivi Raspberry Pi Pico (rp2040) ed un semplice sketch di esempio

RF_E70 e70ttl(&Serial2, 2, 10, 11, 12); 

/*
 * EByte RF E70
 * send a transparent message, you must check that the transmitter and receiver have the same
 * CHANNEL ADDL and ADDH
 *
 * You must uncommend the correct constructor.
