Simple and fast serial library for chips with single hardware serial
speed as FastSerial with tiny size
sizes of sketch DigitalReadSerial from Arduino samples
uses HardwareSerial FastSerial SingleSerial flash 2636 3848 2300 ram static 202 109 203 ram full 253
ram full means: with SingleSerial & HardwareSerial RX & TX buffers allocated statically, where FastSerial uses dynamic memory allocation via malloc()
FastSerial uses 16 bytes TX and 128 RX so full memory usage is 253 bytes HardwareSerial by default uses 64 bytes TX and 64 RX static buffers SingleSerial by default uses 16 bytes TX and 128 RX static buffers
see the above table again :)
restrictions:
- only one port
- buffers 256 bytes max
- no non-blocking write
- buffer sizes must be power of 2
