Hi

Great software - many thanks
I'm trying to work out how to use the S/W with a single bit per pixel (mono display)
I have set 1 BPP in the pio file and 1 pin in config.h
The bit I can't see is where to set the DMA transfer count(s) to reduce it(them) by a factor of 8

I've got the code already for manipulating a 1 bit framebuffer so don't need help on this but just want to get the basic background DMA running and have failed so far

UPDATE: found it :-)

`
*cb++ = WIDTH/32;
cb++ = (u32)&pFrameBuf[lineWIDTHBYTE];

UPDATE-UPDATE

works perfectly in 640x480 by doubling the clock and the various clock counts - just what I was hoping
`
Thanks
