Hello @P55-rgb I checked your project. You must uncomment 55th line in "TM1638_platform.h" file. Annotation 2021-06-29 234542

The project was assembled without errors.

  1. Why is it not the number 8 on the indicator, but this one?
  2. How to clear all digits on indicator?
  3. How do I clear a single digit?

  1. I think your seven-segment display is common-cathode type. Therefore, you must change seven-segment display type in 65th line of "TM1638.h" file. Annotation 2021-07-01 141328

  2. Add this function to your project and call it: void ClearAllDigits(void) { uint8_t Buffer[8] = {0}; TM1638_SetMultipleDigit(Buffer, 0, 8); }

  3. void ClearSingleDigit(uint8_t DigitNumber) { TM1638_SetSingleDigit(0, DigitNumber); }
