pcb assembly company welding anode 7 segments 3 digits.
it is big problem remove 22 pins, resolder 22 pins....
my question :
Have solution to cut and to jumper way to it board working ? ( change vcc to gnd etc ).
Have solution to remake code to change cathode to anode ?
Check picture to undersantd.
I use atmega 168pa

Post the schematic, we can go from there.
yes, pleasy check 3° picture.
You need to change Q1-Q6 to P-channel parts, connect them to +5 insead of Gnd.
I can't tell if your traces will allow that or not.
i can try it in one board, not problem.
but it need will change modify code ?
do you can show me in draw, what need to do ?
i can use jumper wire in air, not problem.
Dear, someone can draw what i need to do, draw are in first post.
Thanks
Eder
