I am using a NUCLEO board with a STM32H7A3 MCU for lab classes in engineering. I am giving basic notions for the inner workings of most digital peripherals, so I am avoiding using HAL functions. Using basic CMSIS macros, we can use register names and...

I want to create a simple demo for a gated timer in STM32F103. I am using STM32CubeIDE but I cannot find the right way to configure Cube and use HAL functions to make it work.I have set up TIM1 timer to run at a 1kHz clock in slave mode (gated mode),...

I used 10k ohm resistors. Anyway, I found the missing piece of the puzzle: Besides the TIMINGR mismatch, I did not configure GPIO_OTYPER for PB8 and PB9 pins to open drain. I thought that when configuring the pins for the alternate functions, they wo...

My Cube/HAL project shows both lines working perfectly.I started to suspect the TIMINGR calculations. Thus, I decided to load the value I found in that register when running my Cube/HAL project. It was very different! (calculator 0x30420F13 x Cube/HA...
