• Hi, sorry if this has been covered before. I have a SH1106 LED device attached to Espruino and it's doing buffered graphics just fine but the performance is not stellar.

    Haven't timed it precisely but looks to take around 50ms to update the screen which gives 20fps.

    I know a little bit about SPI and can see some discussion in issues and elsewhere about the fact that Espruino sends a byte at a time, but could be bulk sending data to avoid the handshake overhead. I also noted the comments at https://github.com/espruino/Espruino/iss­ues/695 that memory is a constraint.

    Is it the case that the Espruino can't spare 1k of data for the SPI bulk transfer (on a mono 64x128 screen)? Or would it not help if the transfer was chunked in to pieces, even if they were only eg. 128 bytes?

    Thanks for a great project.
    Alfie.
