some struct for parameters

For a given value choose apropriate values for ADC gain and PGA gain to reach the given value as good as possible.
(This would be needed for user configuration too)

In local loopback mode, one transfer finishes and was read, then TDRE flag does not rise after the second transfer should be finished.

… or push-pull? depends on chosen hardware driver.

… should work well together with the PGA and give more flexible gain settings

everything from conf.h to board.h? (defines)
everyting from ./ to board/?

define nice pin mappings for external and internal use on PCB

Why won't the SPI controller toggle chip select? Silly thing … -.-

implement commands to alter parameters

SPI is needed for PGA and external Memory that might be used later.

• layout of conf.h, what’s needed and in what form and where to put it?
• consistency of used types
• consistency of comments, file sectioning, descriptions
• find docstring style and apply to functions or leave them out entirely
• file headers for own code

• to set gain
• to check error state
• might set other options

Test if everything works as aspected. Especially speed issues (bitrate).
put some testing wrappers in main() for that (should be neccessary).

(x*VREF)>>RESOLUTION won’t work for 32-bit variables
0xFFFFFF * VREF > 2^31 … for 1.17V and 24bit

store parameters on internal or external memory

Get the prototype running and connected to the machine’s hardware and test it.

Needs output driver, input driver (PGA, for force sensor), new distance sensor, if any, and a way to communicate (serial terminal would be ok, but logging and graph output would be nice).

Communication is broken.
