Hello everyone,
I have built the version 2.11 of Atmega fusebit doctor with Atmega328P as doctor, firmware like here:
https://github.com/SukkoPera/avr-fusebit-doctor/tree/main.
I have tried to connect it to a serial monitor on my laptop (TeraTerm, Bascom serial emulator and Microsoft serial monitor) on 38400 baud, but no success to obtain the right messages. On Bascom monitor I obtain a long series of "C" each time I press the start button, on TeraTerm a long series of "diamonds". I have tried to connect only the TxD from doctor and both TxD and RxD, but same thing happened.
I do believe the PCB circuit is ok, as I have revived 7 Atmega8.
Please help.
Added after 6 [hours] 30 [minutes]:Issue solved, it works at 4800 baud.
