I have question regarding arduino due reset circuit, i have checked schematic, but still not clear for me. Question is if Arduino reset pin can be pulled up by external resistor? and if yes, I guess it should be only 3V3?
Because I have one puss button used for "software reset" by MCP23017 which is running at 5V, I would like to make jumper option for direct connection between pushbutton and arduino reset. But that push button has pull up resistor to 5V because of MCP23017.
Any advice helpful, thanks in advance. Miro
