    Sorry for the delay, I was not on the forum for a while.I never tried it but it should work. I would try to use something more simple and cheaper than a mcp23s17. Maybe a serial shift register like 4094. If you use only one shift register, use 4 pins to for data and two pins for RS and EN, you will have to change the code and break each charchter into two nibbles.

    Hello Barak,

    You have posted a story about how you control a LCD over SPI.
    WOuld this work in combination with a DIY SPI LCD with a mcp23s17 port expander?

    with regards
