Problems with TM1637 display and Raspberry Pi Pico

#1 Post by fullington99 »

Hi all - wondering if anyone else is having problems using TM1637 four digit displays with the raspberry pi pico? I cannot get the displays to light even with bare bones simple code. I've successfully used the same pi pico with a Max7219 display, but no luck with the 1637. VCC connected to 3v3 pico pin, GND to GND and pins 16 and 18 for clock and data. Simple code -

display_chr_code = hw_chr_display_add("Transponder code", "TM1637",4)
hw_chr_display_set_text(display_chr_code, "1234")

Best regards.

I will try to test next week, as I mentioned in the ticket, it has probably not been tested on the Pi. But this is not something that would have to be mentioned on the website as you suggested, because it is something that just has to be fixed by us (if it is really broken).

It might have to wait until Corjan is back in the Netherlands, which is by the end of June.
