Hi everyone,
I’m working with the CH201 ultrasonic sensor using a Teensy 4.0 board. I’ve integrated the sensor using the official drivers from TDK, making the necessary adjustments to work with the Teensy.
While the range data reads correctly, I’m facing issues with the amplitude array. The array seems flooded with noise and contains duplicated wrong data. The amount of duplication seems related to the value defined in "CH_IQ_SAMPLES_PER_READ". Despite the noise, I can observe around 40-50 correct amplitude values at the End/Start of the array.
Interestingly, when I manually read 40 amplitudes from the sensor’s memory, they appear to be accurate.
Has anyone encountered a similar issue or could provide any suggestions for resolving this? I would appreciate any insights or troubleshooting tips.
Thanks in advance!
