A super simple rust driver for any 4 digit 7 segment display, currently only tested on the 3461BS1, however, theoretically it should work for any. If you find any errors with different displays or boards, please let me know.
A working example with the Raspberry Pi Pico.
Here is the pinout for the 3461BS1:
let mut delay = cortex_m::delay::Delay::new(core.SYST, clocks.system_clock.freq().to_Hz());
// Setup for all the required pins
let mut e = pins.gpio1.into_push_pull_output();
let mut d = pins.gpio2.into_push_pull_output();
let mut dp = pins.gpio3.into_push_pull_output();
let mut c = pins.gpio4.into_push_pull_output();
let mut g = pins.gpio5.into_push_pull_output();
let mut d4 = pins.gpio6.into_push_pull_output();
let mut d1 = pins.gpio7.into_push_pull_output();
let mut a = pins.gpio8.into_push_pull_output();
let mut f = pins.gpio9.into_push_pull_output();
let mut d2 = pins.gpio10.into_push_pull_output();
let mut d3 = pins.gpio11.into_push_pull_output();
let mut b = pins.gpio12.into_push_pull_output();
// Creating the LED3461BS
let mut led_display = LED3461BS1::new(
&mut a, &mut b, &mut c, &mut d, &mut e, &mut f, &mut g, &mut dp, &mut d1, &mut d2,
&mut d3, &mut d4,
);
// Displaying characters 2 3 4 C on the board
// Delay 5 milliseconds before settings the next digit, due to the optical illusion of [persistance of vision](https://en.wikipedia.org/wiki/Persistence_of_vision)
loop {
// To set a number, first parameter is a char with the digit you want it to be on
// Second parameter is a char with the number on the digit
led_display.set_number_on_digit('1', '2').unwrap();
delay.delay_ms(5);
led_display.clear();
led_display.set_number_on_digit('2', '3').unwrap();
delay.delay_ms(5);
led_display.clear();
led_display.set_number_on_digit('2', '4').unwrap();
delay.delay_ms(5);
led_display.clear();
led_display.set_number_on_digit('2', '5').unwrap();
delay.delay_ms(5);
led_display.clear();
// To set a custom character, first parameter should be the digit you want it to be on
// The next parameters are segments a-g
// The last parameter is the decimal point
// Look at the pinout of the 3461BS1
led_display
.set_custom_character('4', true, false, false, true, true, true, false, false)
.unwrap();
