Ok, a recap:
With serial0:
1. Parse the ini file. Current ini file (November 2019 firmware) describes block of 99 bytes.
2. Send character 'A' to Speeduino (one byte).
4. Receive 99 bytes datablock.
5. Parse datablock per ini file.
6. goto 2.
With serial3:
1. Send character 'A' to Speeduino (one byte).
2. Receive character 'A' from Speeduino (one byte).
3. Receive 75 bytes datablock. (as per
https://speeduino.com/wiki/index.php/Se ... _interface)
4. Parse datablock per spec.
5. goto 1.
This line of info got me confused:
https://speeduino.com/wiki/index.php/Se ... _interface
"If you send an "A" to the port it will reply with,
"A" confirming the received instruction (sent as 0x41 in hex),
The port will then transmit ALL the realtime data."
So above info is still true, but only with serial3?
