  • I’ve been moderately pleased with this device.
    I mostly got this for it’s text abilities; it has a lot more space than most text only LCDs have.
    However, I wanted to see what else I could do, so I tried doing some (simple) animations. The 416 byte buffer on-board makes this a headache. Because the TX line is unused on this unit, there is no flow control at all, which means you have to guess the rate of drawing on the device and slow down the transmission of the commands accordingly in the (client) software.
    Here’s my Python code that I wrote to control this device, it includes the appropriate client side buffering you need if you’re planning on doing any animation:

No public wish lists :(
