TM1640 8x8 LED Matrix

[mcauser]

I created a library for 8x8 LED matrix modules based on the TM1640 LED driver.

https://pypi.python.org/pypi/micropython-tm1640/1.0.0



I tried to order a Wemos LED Matrix Shield on AliExpress, but received a clone DIY More matrix.
Photos of the Wemos shield show an "AiP1640" led driver.
Not sure how different this is from the TM1640 driver on the DIY More board.

Judging from the Wemos Arduino example code, the AiP1640 chip behaves similar to the TM1640 chip.

Does anyone have a legit Wemos LED Matrix shield that could test my library?

Seems to work great!

As far as I can tell, the AIP1640 is a cheap clone of the TM1640 — they are supposed to work the same way.

I did some research about those chips back when the shield first appeared: https://hackaday.io/project/18120/log/60306 and I even have one, but I never got around to making a driver for it. Thank you!

Wemos confirmed the AiP1640 is a clone of the TM1640
