I am trying to read WiThumb sensor using MicroPython. I managed to install MicroPython and make networking work. However I am having trouble with the sensors.

For example, I was able to figure out from the provided Arduino C code, and withumb schematics, that the temperature sensor is accessible via I2C, at address 0x1F. GIven I did not succeed yet reading the temperature, I guess I am missing something; perhaps initializing the sensor is mandatory, and I am not sure of the correct registers to use when reading/writing over I2C... not being a C programmer by trade, or an electronics engineer, this is really burdensome.

It would be good to have some written, programming language-independent specs on how the sensors are read from and what kind of steps are required.

Maybe related to I2Cdev library or something in the library, or I have the wrong library - I think it's a library issue, but it's a bit beyond me.

Any idea where to start or what to do?

Hi Thomas,

just wanted to point to this example where I made a JavaScript version from your first example:

https://github.com/embeddednodejs/ch_9_making_robots_with_nodejs/tree/master/vehicle

The Fabric shield is really nice.
I was a bit wondering if you have thought about variations for the motor control, e.g. similar to the motor controls of the Arduino shield: http://johnny-five.io/examples/motor-directional/ (throttle/brake) or PWM control of the motors?

BR,

Patrick
