 /** History
+ * 2026-01-17 tonhuisman: Revert to using 'regular' Arduino GPIO functions for TM1637 displays on ESP8266
+ * 2026-01-12 tonhuisman: Fix initialization of number of digits when upgrading to 20260108 build,
+ *                        formatted source with new Uncrustify config
  * 2024-09-28 tonhuisman: Switch to using DIRECT_PIN_IO, to get better timing-accuracy for TM1637 displays
  * 2024-09-27 tonhuisman: Add option to flash dot on second digit instead of the colon for blinking time
  * 2024-08-24 tonhuisman: Add compiletime define P073_USE_74HC595_OVERRIDE that, when, set to 1, allows 74HC595 displays to be included
