Error compiling the provided example script

[juergen-venne]

I get this error compiling the default script:
What do I have to do to get rid of that message?

I'm obtaining that error, too. Since your questiong is from Sep 7, and nobody has answered, I guess this project is abandoned. Desinstalling this library right now.

[AKJ7]

Oops forgot. I will look into it. Thanks for the comment.

[AKJ7]

@jcmadrioso For which platform are you compiling it?

[jcmadrioso]

ESP8266

[AKJ7]

Solved. However the display doesn't work with 3.3V board like the ESP32 and ESP8266. It expects 5V at the DIO and CLK pins. Sending 3.3 simply doesn't turn the pins on. The solution is to interface the 3.3V to 5V.

[jcmadrioso]

Thank you.
But, acording to TM1637 datasheet, the chip works with 3.3V - 5V. In fact, I have used it with ESP8266, ESP32 and RaspberryPi, all of them interfacing at 3.3V, and it works.
I don't know why you say that it needs 5V (see the datasheet).
Best regards.

[AKJ7]

What? I tested it on my ESP32 and it wasn't working. Can you update the library and test it?

[jcmadrioso]

I can confirm that your library is compiling and working now. I have tested clock.ino example with ESP8266 and it works perfectly, interfacing at 3.3V.
I will try with ESP32.

[jcmadrioso]

Yes, working too with ESP32 (ESP-WROOM-32)
Maybe you have an issue with some capacitors in the tm1637 board. Try with a longer bitdelay.

[AKJ7]

Ok. Thanks.
