C Libraries for Adafruit servo HAT?

[GerardWassink]

Hi guys,

Asked this question in another board as well, but thought it would be more appropriate here...

I have ordered this Adafruit servo HAT. It will arrive tomorrow. It works with a combination of !2C and PWM.

From what I can see, all examples are for Python. But I want to incorporate this in a C project that I'm working on.

What libraries are available in C that have been proven to work?

Pointers appreciated,

Gerard

I don't know if this is what your looking for but I found this on my travels

Hi Yam,

Thanks for replying, the post you're referring to, AFAICT, is about the hardware design of HAT's. And I'm not so much into hardware.

Just looking for a library to make use of this specific HAT.

But thanks for sharing!

The Python is about 90 lines of code wrapping I2C calls. It shouldn't take that long to port to C and test if nobody has already bothered.

Hi Joan,

Thanks!

Would you happen to have a url for me pls?

The code is on github.

Perfect, thanks!

I'll have a look at it and see wether I can port it to C.

Hi Gerard,

Did you manage to port the python library to C?
Can you give us some feedbacks about your work?

Best regards,

I decided not to port. I switched to python (having to learn this language first). The result can be found here. The code incorporates the ability to work with the Adafruit servo Pi Hat, as well as with the 16 relay board of my own design, for which I wrote my own driver (also in python).

There's footage of the first test of the relay driver board to be found at my YouTube channel.

Mind you, these efforts are not meant to be used to make "fast cash"

HTH,

IMO that's really a pity that all those HATs don't provide a convenient C lib but just support Python.
As I only use g++ and never will use Python, the company will probably never win me to become a customer for all those HATs...

Not a reasonable company policy IMO, though...
