TM1637 6 Digits

#1 Post by Keith Baxter »

Hi,

The wiki says that the TM1637 can only use 4 digits. @Corjan is it possible to please make it so that these 6 Digits ones can also be used. Widely used for radios and MCP
Thank you

For Arduino use library: TM1637.h.

Apparently it uses a different library so there may be an issue. :?

Quote from here...
https://forum.arduino.cc/t/tm1637-6-dig ... lay/702875
Most TM1637 libraries support displays with 4 digits. I picked up several 6 digit displays that use the TM1637 chip and wanted to get it to work (made by diymore). The TM1637 drives up to six 7-segment LEDs so I expected it to be straight forward. However, the way the 6-digit display modules are built, the two blocks of 3-digits were in reverse order (would display 321654 using standard TM1637 libraries to drive it).

I updated the TM1637TinyDisplay 60 library to now also support 6 digit displays. I added the map and reversed the serial upload sequence to get it to work (now showing 123456). I would like to know if anyone discovers any 6-digit displays based on the TM1637 that do not work with the following code.

Install TM1637TinyDisplay 60 via Arduino IDE.

Here is another discussion on the subject.

@Ralph Also note the WIKI typo in the image. Says Max7219. Also the "Available from AM/AP 3.5." is also incorrect.The named one is correct.

Same "Available from AM/AP 3.5." for the TM1638.

@Ralph

I see that there are lots of errors on the "Hw chr display add" page. I take it you guys are still working on it preparing for the AM4.1 release?

Hi,

We are all gearing up for the festive season and some thing are not as important as others. That I understand. However a non response after two days is worrying.

It is holiday time and I have some savings to spend on my sim. I would like to know if these TM1637 modules could be in my Christmas stocking so that I can build a few extra bits for my sim over the holidays.

Merry holidays all and a prosperous new year.
