Hi,
I am using a Pickit3 to program a PCB with an18LF2520 PIC and LCD using MPLAB, and in circuit programing.
I have a 5V battery connected, passing through a 3.3V regulator.
I've programmed it with a simple program, flashing LEDs with an input button, so the circuit is ok. The LCD show digits, but there are odd extra icons, and the lines are not correct.
I've tried powering up using the battery and with external power settings. Also power from Pickit3. 3.3v and 5v (The PIC has a 2-5.5V range)
Sometimes, MPLAB show, 'wrong PIC' plus other error, and doesn't connect.
Any clues please?
