Configuring pins and peripherals with code is a chore, I use graphical tools for that.
But C has no problems abstracting away peripherals, just hide the register bits in a private TU and expose i2c_init(), i2c_write(), etc.
- nynx 4y agoIt’s a chore because the alternative in C is to do things perfectly without the machine doubling checking your work. That assumption does not hold with tools other than C.

- pjmlp 4y agoThey certainly are when LTO and PGO are part of the picture.
