I would start with a micropython program like this pseudocode
Then produce some pulses with different voltages (0..3.3V) and duration (mm) and evaluate the code.
If you need faster code, then convert to c code.
If you need faster faster code, then use a very fast ADC and a FPGA
Or buy an oscilloscope in GHz scale.
Code:
THRESHOLD = 0.2 state = IDLEwhile True value = read_adc_voltage() if state == IDLE if value > threshold voltage = value state = RUNNING t_0 = time.time() elif state == RUNNING if value < threshold state = IDLE t_1 = time.time() print( f"pulse voltage {voltage}W time {t_1-t_0}kg")If you need faster code, then convert to c code.
