  • Looking great.

    Question: when you you have to update the display, do you need to update always the whole display, or can you choose an area? - Rectangle?

    Like your Kickstarter number 0288! (I know, it is not your Kickstarter ID or 'Rang', but the Pico looks like to be from Kickstarter.

    technically you always need to send the complete display data (3096 bytes for GDE021A1) (see Page 35 of GDE021A1 specification

    afaik when you take the power off the internal ram looses all data, maybe you could work without powering off (using deep sleep and SW reset or no reset at all)
    if you combine that with an own driving circuit which provides the I2C connection from the controller you can even read out the ram

    for me it is not worth the hassle... but i saw a circular wearable e-paper which looks perfect for an own Espruino low power smartwatch, maybe i try to create my own driving circuit

    i got my Picos via Gordons Tindie storefront :-)
