Скачать или смотреть Clock and stopwatch in MicroPython for the Kitronik ZIP Halo HD

A clock and stopwatch written in MicroPython with many background display modes on Kitronik's ZIP Halo HD using the BBC micro:bit V2. Kitronik ZIP LEDs are RGB pixels which can display any colour, similar to Adafruit's NeoPixels.

The ZIP Halo HD has a MicroChip MCP7940N real-time clock (RTC) on it which is providing the time for the clock mode. This is enhanced with utime.time_ms() to provide finer resolution and is needed for the sub-second display on the stopwatch. The trim feature is used on the RTC to improve the accuracy and MicroPython clock/time is corrected to deal with a MicroPython bug.

The video was shot with the camera in daylight colour balance in a room with subdued lighting. The brightness level is around 16 for red, green and blue values on the ZIP LEDs. The maximum is 255 which the datasheet states is 15mA for (255, 255, 255) per LED.

The power is from three recently charged NiMH AA batteries in the battery pack on the back of the ZIP Halo HD.
