I was looking at some slides that I found called STM32H7- CORDIC co-processor (CORDIC, Revision 1.0) and noticed the following on slide 6: According to this, the fractional number being represented by the fixed-point integer bits is (-1)^s multiplied...

I am using STM32CubeIDE (v1.15.1) to develop firmware for an STM32G431 MCU and attempting to configureTIM8 to use dithering. I have defined the following constants:TIM8_KHZ = 20TIM8_PRESCALER = (1-1) = 0TIM8_PERIOD = (((16*170000/TIM8_KHZ)/2)/(TIM8_P...
