Foot Contact Switch connection #45

Closed dvogureckiy99 closed 2 years ago

Hi, how does Foot Contact Switch v1 connect to Micro Driver ? As I understand it connects to ADC to one of the Micro Driver MCU via U$12 contact.

fgrimminger commented 2 years ago

Hi, each Micro Driver has 2 ADC ports which are evaluated and transmitted at 1kHz. You want to supply the foot sensor with 3.3V - that's the maximum voltage of the ADCs. In this schematic the ADC ports are labeled with ADC-A6 and ADC-B6. adc_microdriver

that is, I can connect 2 sensors to one board udriver?

fgrimminger commented 2 years ago

Yes - that's possible. In that case the sensors will have to share the 3.3V and GND connection. It might be less convenient for assembly and repairs to have both sensors on a single Hirose connector. It might make sense to connect one sensor per Micro Driver board and use a individual 3pin Hirose connector for each one.

Thanks!
