Resolved! STM32F7 USB CDC Device Descriptor Request failing
I am struggling to get USB CDC working. I am very far down a rabbit hole and I'm completely stuck.I am using HAL libraries for USB_OTG_HS on the STM32F746ZGT6, with a 16MHz HSE.I am running in bus powered mode, VBUS detect disabled, and I have hardwi...
Resolved! PWM problems
Hello! Recently I got into STM programming for my internship and I cannot figure out register level programming yet, I have this piece of code ```RCC->AHB1ENR |= RCC_AHB1ENR_GPIOAEN | RCC_APB1ENR_TIM2EN;GPIOA->MODER |=GPIO_MODER_MODE5_1 | GPIO_MODER_...
Resolved! STM32 ADC DMA low raw/Voltage readings
Hello,I am experiencing the following problem. When I setup an ADC with DMA for 5 channels, occasionally I get lower readings than the expected ones. It also happens in some of our hardware of our production, but others perform ok. We have inspected ...
STM32U575 Independent watchdog timer
Hi, I am using stm32u575 uc trying to use independent watchdog for time 1.2 sec for custom board. The clock configuration is as follows: static void SystemClock_Config(void){RCC_OscInitTypeDef RCC_OscInitStruct = {0};RCC_ClkInitTypeDef RCC_ClkInitStr...
STM32H7 TTCAN Time Reference Messages with External Loopback Mode?
Hi,Problem: I'm getting errors when trying to send ttcan time reference messages while FDCAN1 is set to external loopback mode.Description: I have an application where we are using TTCAN effectively with one device acting as a TTCAN-Master and sendin...

Resolved! Cortex-M0 Thumb alignment
Hi everybody,I am using STM32F042G6 MCU for an automotive project and since It doesn't have mush FLASH (32kB) I am trying to reduce code size as much as possible.Lookign at the linker file generated by STM32CubeMX, I see that instructions are aligned...
How to precisely control GPIO pulse width using instruction cycles?
The STM32F429 processor operates at 180MHz, with a clock cycle of 5.56ns. Can we generate pulses with a width granularity of 5.56ns using only ARM instruction delays?For example: 5.56ns, 11.12ns, 16.68ns, 22.24ns?In practice, I have encountered diffi...
Resolved! G431 - reset counter and prescaler on input capture
Is there a way to reset the counter and the prescaler via a hard event or something when an input capture happens?I use timer 1 to have a hall interface and to drive timer 8. But there are some fluctuations, because the interrupt (where i reset count...
