Resolved! STM32G474, HRTIM Blanking / Windowing documentation is contradictory
I need to detect if there is a comparator state change inside a PWM pulse. I want to look for this a little after the PWM rising edge and stop before the PWM falling edge.The PWM is running in center aligned mode.RM0440, Rev 4, STM32G4 Reference manu...
Resolved! How to find pin to pin compatible replacement to specific micro-controller?
Hi,I am using STM32H743VIT6 for prototyping, but for production I may not use such powerful micro-controller.How to find pin to pin compatible replacments for this micro controller?
STM32F4 Ethernet issue with firmware version V1.25.0
Hello,I ran into a problem with Ethernet using an STM32F407VET6 microcontroller a few weeks ago.That time I have searched this problem and found somebody facing the same issue and conclusion, but I did not found that thread now.So using the latest HA...
Resolved! Using STM32F407VG Discovery Board's Debugger to debug STM32f0304P6
Hello. This is my first post here. I'm pretty unexperienced at the hardware side of MCU's and I want to debug my STM32F304P6 processor (on an unofficial board) through debugger of STM32F407VG Discovery Board. I connected SWD pins ( 2nd to CLK, 4th to...
Resolved! Custom I2C pins on STM32F103
Hello,I would like to implement an I2C master on an STM32F103. It's pretty straightforward to select the IO's using cubeMX and to generate the code, but I don't want to use either of the available pins for I2C (PB7,PB6 or PB9,PB8). I need to use PB5 ...
Why are some I/O pins on stm32f303 permanently pull-up under reset?
Due to stm32f303rct6 refrence manual (RM0316) p. 243, the reset value of GPIOA_PUPDR register for PA8 and PA11 are equal to 00. This means that the output of them are not pull-up or pull-down under reset state,but In my practical test, PA8 and PA11 a...
Resolved! Understanding Flash Operations
Hello,I'm developing on an STM32F207 (datasheet). I am attempting to modify a couple of the internal Flash sectors (the 128kB sectors 10 & 11 to be specific). I'm trying to figure out how to do this in a way that will not block the CPU. Let's say I'm...
Erasing flash sector works, but writing it causes HARD FAULT
I am trying to write data in the flash of an STM32F446RE, sector 5.My linker script is configured so that .user_data goes to 0x08020000, and:__attribute__((__section__(".user_data"))) char userConfig[4] = {1, 2, 3, 4};Is my user Data.If I read it aft...
