I have a custom board with LPC54608 mcu. In my application I use 7 inch resistive touch screen. touching detects via adc channels . Sometimes when I power the board ( especially after loading new firmware ) adc channels stuck and no touch can detect. Any idea about this problem ? Is it about hardware or software ? How can I understand the reason of problem ?
