TM1624

Will this code work with TM1624 led driver?

Hello @blackhawk2611 ,
A quick look at the datasheet showed that the TM1624 has these features:

• segments x digits: 11x7 - 14x4 seg x grid (common cathode)
• interface: DIN/CLK/STB
• buttons: n/a
  Based on these features the best match of currently supported chips is TM1620, followed by TM1628 and TM1668.
  Since I don't have a TM1624 in my collection, I cannot test to see which class is most compatible. I think that driving 8 segments will probably work; using more than 8 probably not correctly. How many segments do you want to use? Do you have a module that uses this chip? If so, can you post a picture?

I suggest you to test them yourself and let me know your findings. I've added this chip to my wishlist and once I have one to test with, I can add full support to the library.

Note to self: 14-segment support: segment 11 is present => different mapping than TM1628/TM1668
Display modes:

• 00=4grd x 14seg (defTM1616)
• 01=5grd x 13seg
• 10=6grd x 12seg (defTM1620?)
• 11=7grd x 11seg (defTM1628/68)
  Power on default is probably 7grd x 11seg

Many months have passed since you submitted your issue. Finally I can mention some progress: Some time ago I've purchased some TM1624 chips. I've implement support for that chip in a generic class in an experimental branch, to be merged at later stage after some more testing. You can read more about that class in this comment of issue #54.

If you're still interested, could you please try that generic class using the definition IC_TM1624and let me know your findings?

Update
Yesterday I published TM1624.h, which offers support for the TM1624 via the TM16xxIC class. I have tested the TM1624 myself on the CH32V003 in 14x4 mode with an 15-segment alphanumeric LED display.

The TM16xxIC class was merged in the main branch, and the experimental branch will be removed at a later moment.
