PIC and animation on GLCD

[MrGG]

is it worth to pursue a project with a PIC18-24 family to do some animation graphics on a 128x64 GLCD I2C, SPI or parallel interface? I have not seen many examples on this topic and I wondered if anyone knows if they perform or are kind of sluggish.
thanks

I've not done it using a PIC, but have done it using a Cortex-M0+. I can tell you that I2C and SPI are both too slow (assuming your animation is more than 10x10 pixels!). In my case I had 4 bargraphs going up and down in real time, along with displaying their values below each one. Using a parallel interface to drive a color 320x240 screen, it was no problem making it look pretty fluid. Even so, I was only updating the bargraphs themselves and the text several times a second, and not the entire screen. No matter how you hook it up, it'll go easiest if you're careful to only update the pixels that actually need updating, to reasonably minimize the amount of data you have to send to the screen.
