Rotating digital picture frame

Posted on Thursday, July 12th, 2012 in project logs by DP

Marcus designed, and built a servo powered rotating digital picture frame, that rotates depending on the picture orientation. A 2.4” LCD is mounted on a servo, while both of them are controlled with a small 28pin PIC32 connected to an SD card.

I connected a 2.4″ LCD with a resolution of 320×240 pixels which I got from ITead to a PIC32MX120F032B using the PICs Parallel Master Port (PMP) peripheral. The display is setup to work in 8-bit mode, so using the PMP was a bit tricky, but I managed to get two 8-bit writes out of a 16 bit transfer by connecting the appropriate pins to two 1N4004 diodes and a pull-up resistor leading to a logical OR for the nWR signal.
