I'm going to sound old and very uncool but ... Use C! I'm in the process of doing my first "serious" project in 'straight' C (I'm a C++ guy from long ago) and it's taken me a while to get into it properly, but I'm starting to get its philosophy and it's becoming easy. But also, in the embedded space, it clearly has all the support you could ever want. I'm also gradually falling for Zephyr (https://www.zephyrproject.org) that has all the support for (eg) callbacks, all sorts of low level stuff. And one more ... the way you'd solve this in Zephyr is to use the scary simple API (https://docs.zephyrproject.org/latest/reference/peripherals/...). https://github.com/zephyrproject-rtos/zephyr/blob/master/sam...
