Hello,
since Google search does not really help, here my question.
Has anyone ever successfully used a AD7705 ADC with the Teensy3.2? I somewhere read people done it...
There are literally no tutorials, even not on arduino. Not being a pro, this is frustrating.
Background is a Loadcell project with 3 Loadcells where I need higher speed than 80Hz (HX711), while 16bit precision is enough.
Any help would be highly appreciated...

Cheers Dan

Hi Dan,

When I googled for "ad7705 arduino", I got a lot of hits.
For example, here is a tutorial and a library that should work on Teensy as well, since the ADC comminicates over SPI.

Hi Paul,
Yes, that is the only tutorial and library I found.
When I try to use the example from the library with the wiring of the tutorial, the sketch stops in setup when the AD7705 gets initiated. No clue why...
... and since there is no other tutorial around, it's hard for me as a noob.
Does the Teensy SPI stuff work the same as the arduino SPI stuff?
In terms of terms in the sketch?

Cheers Dan
