Perhaps you could add to your TODO-list another book, then, when you feel you have enough free time for such an endeavour again? Say, “STM32: Advanced Topics” or something, where you take a look at USB and networking and possibly something else, for example?
Aye, well, I’ll just try to write my own stuff from datasheets or port code over from Arduino/mbed/the old peripheral library if needed. I can always chuck it as more homework for myself. Getting some more practice can’t hurt…except when I’m banging my head on the wall when I can’t make things work! 😉
I know it’s intended for professional usage and I am not expecting the kind of ease-of-use as one would get from the Arduino-environment, if that’s what you were thinking. I wouldn’t be here if I was afraid of going through some effort to learn more, you know. I was merely asking if there is any good source for this kind of stuff or not. From your response I take it that you aren’t aware of anything such and as such I consider my question answered.
