C programming sense-hat

[experix]

I installed the sense-hat software and found 2 examples of C programming in /usr/src/sense-hat/. Have not found device documentation yet except for a block diagram and the schematic PDF. I want to write C programs to operate it. Are there more resources available? How about a list of ioctl's, library calls and so on and what they do?
'sense-hat' and 'astro-pi' seem to be equivalent terms-- is that correct?

Sense HAT refers to the board itself. Astro Pi is the whole unit assembly up on the ISS.

You'd mostly be talking to the devices directly over I2C, so you'll need to get the datasheets. The joystick and framebuffer are the only ones which are proper linux devices (so the standard documentation from the linux kernel applies to those).

Maybe this is useful info: http://pinout.xyz/pinout/sense_hat

Another approach would be to reverse engineer the Python source code.

This isn't too big a challenge, the python library just talks to a C++ library for IMU sensors that is up on GitHub, same user as the Sense Hat python repository. Pure C programming is easily possible, but the IMU library has a lot of huge benefits like sensor fusion.
