Graphical Displays with PBP3

Seems there is an error in the word DEMO. Looks like DEMC

one thing i cannot master is taking a video of led displays that shows the true colours especially if the display is multiplexed
there is no error the camera does lie

Are you using the WS2812 LEDs?

at 512 pixels per panel * 8 panels * 3 colours [24 bits] per pixel = 12288 bytes , no 8 bit pic to date has that much memory so no,
google "p10 rgb led module"
thats 3 bits per pixel or 1536 bytes but 1/4 scan multiplexing needed [the panels come in various flavors of multiplexing format]
my code only supports AB zigzag format

Hey Richard, just out of curiosity, is this written in PIC Basic? I’m guessing probably not. Either way, good job!
In the meantime, I’ve switched from Basic to C and to the RISC-V architecture.
But from time to time, I like to look in here to see what’s new.
This forum gave me a lot of useful information, for which I’m grateful, so I’m glad it’s still active and alive here.

yes it is in pbp3, although crucial bits that need speed are done in asm code. its customized to run on pic18fxxk22 series
it can support 1 to 8 panels

i do have better C versions that support up to 10 panels in xc8 or xc16 running pic18f47q43 and PIC24FJ128GA204

Does anyone know how to work with these small SPI displays that use st7789v driver?
These are very small but seem to have lot's of potential.
