Here is a short clip of your example running on the RP2040 PICO, using my TM1640 16x8 matrix. As you can see it works for me. I added this line...

Are you experiencing similar behavior as i did? (See also video below) To test I used the TM1640 matrix example, with 16 columns and 8 rows: ``` #define MATRIX_NUMCOLUMNS 16...

Hello, it is possible to reduce it to one extra line per module, by sharing the data line. Each additional module then has its own clock line. In the TM16xxGFX...

FYI, with help of a friend with a better scope I again looked at the signals from the PICO at time of the glitching. Unfortunately I didn't see anything special...

Another round of testing the RP2040 Pico gave some interesting findings: when using a module with the smaller (3mm) LED-matrices and printed circuit board, there was no glitching. After updating...

Thank you for your contribution! I don't think I have the TM1620B in my collection already. I will see if I can find and order some on Ali. May take...

Hello @gary7530 , thank you for your suggestion. I know that for I2C it is custom to only drive a pin low when sending data and keep it floating on...

Hello @YeWuChen , Thank you for submitting this issue. It's great to read you found a workaround for the issue you encountered. Some time ago I encountered [stability issues with...

FIY: During recent work on developing a generic class to support untested TM16xx chips, I used the RP2040 to test things. I fixed the halting issue for RP2040 (and also...

Excellent! Thank you for sharing this nicely illustrated experience. It's interesting to see the various devices in the wild that use a TM16xx chip. I get inspired by reading how...
