Where to start STM32F4 + tm1638 (led tube)?

Question

Drivers

Hello.
There is an STM32F4 board and a board with a led tube + 8 two-color LEDs + 8 buttons on the tm1638 controller. Bought on aliexpress .
I can't find anything to start with. It’s just that when I started looking, I found similar boards a little different with 5 legs, and I have 10 for the input.
On what protocol / bus / interface to try to work with it. Maybe someone has some kind of library to start with.

Answer 2

You need to start by reading the datasheet for what you are connecting. Optionally - a datasheet for what you connect to. It becomes clear what kind of interface.
For lazy and unwilling to understand - googling, but it's not interesting ...
