Resolved! Problem reading analog values from 3 different potentiometers on STM32 Nucleo-F446RE

I have been trying to use three pots as dials for a guitar effects pedal project. Their purpose is to simply read the voltage from 0 - 3.3V and with some scaling (to turn the raw readings into 0-100 values) in the code to store these 3 values inside ...

Resolved! How do you measure the execution CPU cycles for a section of code?

I am running a STM32F466RE with no OS, using the STM32CubeIDE. Is there a code profiler, or some other way I can measure how many CPU clock cycles it takes for a certain section of code to execute? I am trying to compare different methods of processi...

Resolved! The datasheet for STM32H745xI does not give the value for R_ADC. Where can it be found?

The datasheet for the STM32H745xI (doc DS12923 Rev 1) states in the notes to Figure 43 (p 191) that the value for R_ADC can be found in Table 96, but it is not given in Table 96. I also cannot find it elsewhere in the datasheet. Where can the value o...
