Arduino Uno to Attiny85 float communication problem
Uno code:
Attiny code:
Error:
**Error:
Uno sends CMD_SET_DELAY, float bytes, and checksum.
Serial monitor shows:
Programming ATtiny with delay: 5.00
ATtiny did not acknowledge - programming may have failed
Can't confirm whether ATtiny receives any command or fails silently.
Manual Trigger Works, UART Trigger Doesn’t
so, I think the bytes from uno are not properly being received
float value not sent I think.
float value not sent I think.

I would start with some basic test code. Have the Uno send "Hello World" and the ATtiny receive it.
