I will arrange the I2C communications with Bus, there will be a single line and I will use a 4.7k pull-up resistor on this line.
I used 32,768 Khz crystal for CH340T now I see that I didn't connect capacitors
The voltage reading circuit was wrong, I realized later, there is no GND line, no frontend, no inamp, so many shortcomings
I put the CH340T in the project requirements as USB to Rs232 conversion is required.
Atmega 328 has some shortcomings, I couldn't complete it yet
Do you have a chance to read the project requests and tell me what to do?
