Embedded Rust BSP with µFerris & XIAO: Getting started with µferris-bsp

Interesting when i commented out all the write_seven_segments with the some digits except one, in this case the second digit, the second digit worked fine, but also the 3rd digit lit up with the same digit but slightly dimmer. It followed the same pattern of always lighting up the digit after the one chose with a dimmer version. for _ in 0..250 { uferris.write_seven_segment_digit(SevenSegDigit::Digit1, None).unwrap(); //uferris.write_seven_segment_digit(SevenSegDigit::Digit1, Some(digits[0])).unwrap(); delay.delay_ms(1); uferris.write_seven_segment_digit(SevenSegDigit::Digit2, None).unwrap(); uferris.write_seven_segment_digit(SevenSegDigit::Digit2, Some(digits[1])).unwrap(); delay.delay_ms(1); uferris.write_seven_segment_digit(SevenSegDigit::Digit3, None).unwrap(); // uferris.write_seven_segment_digit(SevenSegDigit::Digit3, Some(digits[2])).unwrap(); delay.delay_ms(1); uferris.write_seven_segment_digit(SevenSegDigit::Digit4, None).unwrap(); // uferris.write_seven_segment_digit(SevenSegDigit::Digit4, Some(digits[3])).unwrap(); delay.delay_ms(1); } Regards, R

Hello, it seems your sequence is off. You are blanking and then activating. It should be more like:

Some(value) // Activate value on seven segment
Delay // Keep it on for some time
None // Blank

Thank you , that worked
