hello...all,
I used PIC18F4520 in my project, I had a problem in pcb design.My code work line in developmnet board but when I moved it to my own pcb the noise occured (In single side pcb with polygon as ground). The push button sometimes has good respon, sometimes not, it often contacted it self although I don,t press it.
I will use double layer to reduce the noise. Could you help me how to design a good pcb with little noise? Which one is better ground plane on top or bottom layer?
thank you.
andrea
