Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I am using a explorer 100 with attached lcd display. I am looking for a way to read the colour a pixel is set. I thought I remembered that you could read the pixel colour in the past but I cannot find it in the manual. Is there a way or do I remember it wrong?

You need to make sure the RD pin to the display is connected and configured using

OPTION LCDPANEL SSD1963_x,L,,RDpinNo

Then just use col=PIXEL(x,y)

Next problem I try to program the explore 100 with the new firmware but MPLAB (latest version just downloaded) does not show the PIC32MX470 it goes to 460 and so it will not program the chip with my Pickit 3. How to program it with the new firmware?

Thanks.
