I added a section to the Cerberus page for possible future features. Here’s what I added so far:
On the STM32, the ADC is able to read the voltage on the VBAT pin. This allows the processor to monitor the charge of the battery connected to that pin, even if it is a bit higher than 3.3V. It would be nice to have this feature exposed to managed code.
The STM32 includes an internal temperature monitoring peripheral. It would be nice to have this feature exposed to managed code.
