a213m This happens when you have an Arduino with incorrect or no firmware uploaded. I was able to reproduce the same behavior by connecting a "blank" Arduino board and starting the program.Does your Arduino board respond to commands "t" and "s 11 99" using serial monitor? Show me the output.Do you have Arduino Serial Monitor open when launching the GUI program? If so, close it. Make sure you don't have any extra Arduinos or any other serial devices connected.Do you have a DIMM present? The GUI will not show any devices present unless at least one DIMM is present, even if you have the board with the correct firmware connected.
PropretorThe program really lacks the read protection feature. That is, not only the removal and set, but also the display of the current state.
PropretorNo, I ran the program without Arduino. Apparently, this explains everything.
a213m No. According to schematic, closed jumper is for 5V/16mhz boards, open is for 3.3V/8mhz boards.If the jumper is open on your board, then you'll have a 3.3V output on the VCC pin.
PropretorI apologize for the poor knowledge of Arduino. In addition, my Arduino boards are still being delivered and not received by me. But for compatibility with the GUI version of your program, do I need to use 7 or 12 pin?
PropretorYou want to say that without altering the code, I can use any of the contacts 4-9, 10, 16, 14, 15, A0-A3 ???
a213m You'll only need to edit the value of HVSW constant to match digital pin number.
Propretora213m You'll only need to edit the value of HVSW constant to match digital pin number. Sorry, but where?
a213m In the sketch, before uploading it to Arduino.
