Hello.
Recently,i install a new seven segments display instead of failed one
in an air conditioner display pcb and i wondered if i can
change,also,the MCU in the same manner(if it was failed)as the 7 segments display.
I mean:if i need to buy 7 segments display,i can buy it by looking for a one that is
with the same specification and install it.
If i need to replace a failed driver(in my case HC373/D type latches)i can find it
by this code and solder it.
As you can see without any special...
Do i need to program a new MCU before solder it to the pcb?
