@Gordon I have not seen a bigger display for sale, however, I found this presentation from the manufacturer which refers to larger and even colour displays using the same technology.
Yes, the C -code is due to the odd layout - its sort of interleaved as well with bit 0 of a 24 bit chunk in one column and bit 1 in the next. There is a good write up here in Technoblogy where I noticed the display.
It would be great if the fill/setpixels code was included in Espruino in some way as it would make the driver much faster.
PS Very happy for the ST7302 module to be included in the Espruino module library although not sure how that works with embedded C.
