- Title question. I do not need any receive communication pins, only transmission.
Actually, I need as many transmission pins as possible on any Arduino besides a Mega2560 (to re/write the EEPROM of slave devices). A Mega2560 has 23 TX/RX pin pairs.
Maybe I'm misunderstanding serial communication. And maybe some sort of multiplexing deal can work like One-Wire temperature sensors...such as
SoftwareSerial serialOne(2, 3); // Software Serial ONE SoftwareSerial serialTwo(8, 9); // Software Serial TWO // RX, TX
- Is there a way to make all the pins using SoftwareSerial TX? Or do half need to be RX?
