I made my first STM32 board (with STM32H743ZI). The core software is not pure STM, but it's based on an official Arduino core for STM32 (stm32duino), which in general makes things easier, initializing GPIOs etc. I am able to program the MCU (via stli...
In my STM32H7 application I start a timer, stop it in an update interrupt handler (by setting ARR to 0), then when appropriate I set a new ARR value thus restarting the timer. This happens very frequently. During each such period I execute a number o...
I wanted to check speed of trigonometric operations on my Nucleo L432KC. I toggle pin state and look at my oscilloscope. I use Arduino IDE.The calculations for trigonometric functions turned out to take several hundred of clock cycles. I was disappoi...
