SD card on the due #10

@jvoermans I think things start to take shape :) . Just a small question: on the due, you well use the separate SPI header to talk to the SD card, right?

Are all the external sensors on I2C, or is any of them on SPI too? Can you make a list of all the additional sensors you use?

jvoermans commented 3 years ago

Yes. I made a diagram, see attached. Example

All sensors are I2C. Pressure: https://bluerobotics.com/store/sensors-sonars-cameras/sensors/bar02-sensor-r1-rp/ 2 or 3x Temp: https://bluerobotics.com/store/sensors-sonars-cameras/sensors/celsius-sensor-r1/ Sonar: https://bluerobotics.com/store/sensors-sonars-cameras/sonar/ping-sonar-r2-rp/

and a wind anemometer, but this is probably analog.

Ok, sounds good. That means we may need 6 ADC channels in total then :) Should not be a problem.
