Resolved! Using SWD pins as GPIO
Hi,at the moment on the STM32U5G9 we have the SWD pins (SWDIO and SWCLK) set to DEBUG, but we would like to also use them as GPIO after programming. How do we switch them to GPIO at runtime? Thank you

Resolved! Unable to program my GPIO image on STM32H750B-DK
Hi ,I am not sure but my development board STM32H750B-DK may have some issues and I need some help to find what it may be . As per the readme.txt (there is very less literature that I could find on this board) , I could dump the ext_mem boot bin int...
I can't get spi communication.
Hello.I tried to use an imu that was previously working using the spi2 port of the stm32f4 series with the spi4 port of the stm32h7 series, but I cannot communicate with it. (imu is using icm42688p.)Is it possible that I have made a mistake in my set...
Resolved! HAL_ADC_Start_DMA caused main loop to become blocked?
Hi, I am configuring the ADC in single-channel continuous conversion mode using DMA. However, once I call HAL_ADC_Start_DMA(&hadc, &AD_RES, 1), the main loop stops executing, and the HAL_ADC_ConvCpltCallback() function is not triggered.I noticed that...
Unable to READ SPI Rx data from NRF24(Slave) into STM32F103(Master) via MISO
I have setup my NUCLEO-446RE as my transmitter and it works fine, But i am not able to read any data at the Receiver i.e. the blue pill. Main things i noted are: -> The MISO pin in any stm32F4 MCU has a function of "Alternate Function push pull" with...
RTCv2 coarse calibration remarks
While the Coarse calibration in RTCv2 is obsolete, in 'L1 and 'F2 it's the only method (and I know 'L1 is NRND, but it's still around and will be for years to come, if ST sticks to its commitment), and as long as it's mentioned in 'F4 it should be pr...
STM32 ADC and DMA with LL libraries
Hello everyone, I'm trying to sample some signals inside a timer ISR. I use all three ADC units of the mC (multiple channels in the first unit and 1 channel in each of the other two units) and I use software triggering and DMA transfer.This operation...
STM32u575 GPIO and DAC output using a timer triggered DMA
Hi everyoneI'm trying to get involed with the nulceo STM32u575 board developing an application that should perform synchronously a GPIOB pins output configurations over time (periodic) and set a specific analog value to each GPIO pins, So ideally I'd...
Resolved! STM32U0 reference manual inconsistent? (exti lines and nvic)
Hello together,I'm a little bit confused by the NVIC and EXTI description in the RM0503.The NVIC vector table says the RTC / TAMP interrupts are combined EXTI lines 19 & 21 (on page 302).But when looking at the EXTI line connections table (on page 30...
Resolved! One by one port pin configuration locking
There is no clear information in the reference manual about port pin configuration locking one by one. For example (desired code): void SomeFunction() { // locking pin configuration one by one LL_GPIO_LockPin(GPIOA, LL_GPIO_PIN_0); LL_GPIO_Lock...
