Hi,
I send data from adxl via ads1256 and teensy 4.0 to PC via USB. I have some issue about noise. If I connect it to PC I have OK noise. But if I connect to tablet or notebook, the noise is 10x higher. Same code, same wiring, same usb cable, same python app, very different noise. All powered from USB cable.
See pictures:
PC noise:
Tablet noise:
Any idea why?
Thanks
