Module tm1637_gpio_driver::fourdigit7segdis

Utility functions on top of the TM1637 driver to display content on the 4-digit 7-segment display by AZDelivery. You can use them but you don’t have to. They show how the driver works/could be used.

Constants

DISPLAY_COUNT

We have 4 displays so we can display 4 digits.

STOPWATCH_MAX

Maximum value for stopwatch.

Functions

display_current_time_in_loop

Displays “hh:mm” with blinking double point on the display. Blocks the calling thread because this is an infinite loop.

display_stopwatch

Starts a stopwatch aka counter from 0 to 9999. You need to provide a sleep_fn that waits 1s (for stopwatch).

display_text_banner_in_loop

Displays a text over and over again. The text will move “animated” accross the screen from right to left. Blocks the calling thread because this is an infinite loop.

display_timer

Starts a timer from x to 0. Needs a sleep_fn (probably one that sleeps for one second / 1Hz). Displays pure seconds. No minutes:seconds.
