#85624 - Strange Reset Problem |
I designed a microcontroller board for graphics LCD 240x 128, I have a weird problem, the power on reset works fine but the reset button halts the microcontroller up. I tried the microcontroller on another different board, the reset button works fine as well as POR.
I'm using a microcontroller with built in reset circuit. When I power the circuit, the LCD displays a nice picture but when I press the reset everything disappears and the controller goes into comma untill power off, wait few seconds, power on again, what could be the problem? I replaced the reset switch for another new one with no success. Mahmood |
