TM1638 Display and Button Module | STM32 Tutorial #96
In this video we will develop and describe a library for the TM1638 display&button module. We will also explain how to interface a 5V module with a 3.3V STM32 and how Open Drain GPIO is actually functioning.

Hurrah!
Fixed all the dodgy LEDs on my TM1638 LED&KEY module, then completed and published the code for my easiTM1638 Arduino library.
Never encountered so many dim or plain not working LEDs on one small board - I ended up replacing 3 out of 8!
Enjoy!

Hoping for a bit of inspiration, or even an explanation...
I have a #TM1638 LED&KEY module attached to an Arduino. I have no issues with the code.
I do have issues with a 2 of the LEDs. I can see that they work, but 1 is dim and another is very dim. The board has no current limiting resistors as the LEDs are pulse driven. I can turn them on and off, so I know they work somewhat.
I could replace the LEDs, but without knowing why they are dim, I think it might not fix the issue.

As I work on my #Kim1 emulation project rabbit holes, I am having a lot of fun with various LED 7 segment displays, or rather the #Arduino library code for the driver chips!
I already have a library for a Gotek 3 digit display that uses a #TM1651. I wrote this 6 months ago while in a rabbit hole as I upgraded my Gotek.
I am adapting it for a 6 digit display that uses a #TM1637, and for an 8 digit display that uses a #TM1638.
And I am also playing with an 8 digit display that uses a #MAX7219.
