Resolved! Does the STM32H5 support multi-drop SWD / Serial Wire Debug v2?
I saw that at least some H7 parts do. The H5 core is newer.However, I could find nothing in the reference manual or datasheets.

Resolved! Combine USART and USB for bootloader selection?
I had a passing thought. I have two pins that I can connect to a PC in my enclosure. I'd like to use USB OR USART. I'd like the PC to select.My idea was to tie the pins together and let the bootloader's selection process pick the correct one on the c...
Interrupt fires multiple times on EXTI9-5
hi, I'm working on a STM32F303CC. on this mcu I'm using 6 buttons as interrupts. 5 of these buttons are connected to EXTI15-10 and one to EXTI9-5. the buttons on EXTI15-10 are working perfectly fine. although, the button on EXTI9-5 fires an incredibl...
Resolved! how to only output stm32 pwm CH1N and disable CH1, in "pwm generation CH1 CH1N" mode
the below code is not working for me //HAL_TIM_PWM_Start(&htim15,TIM_CHANNEL_1);HAL_TIMEx_PWMN_Start(&htim15,TIM_CHANNEL_1);
PWM Generation CH1 CH1N doesnt work?
Hi, I have STM32F091RCTx and want to send PWM generated signals on 2 PIN's.//... HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t*)LedData, LED_DATA_LENGTH); //... void HAL_TIM_PWM_PulseFinishedCallback(TIM_HandleTypeDef *htim) { if (htim ==...
Resolved! All EXTIs triggered at same time
I configured the EXTIs for 16 inputs from PD0 to PD15, rising and falling edge, IRQ1 for PD0, IRQ2 por PD1, and so on as must be for groups 5-9 and 10-15 IRQ Handler. I debug the program with a breakpoint in each EXTI_IRQ_HANDLER and all of them are ...
RTC registers TR and DR gets cleared when coming out of stanbymode
Hi Im using the stm32L4 , and if not coming out of standby mode I update the time variables. And all works as expected, It goes into standby mode using the following after a period of time. "HAL_PWREx_EnableSRAM2ContentRetention();HAL_PWR_EnterSTAN...
What is MSP for?
Posted on April 20, 2016 at 18:24This is a maybe stupid question but I cannot find a good (for me) explaination of how to use them. What the acronym is meant for?I see in the docs'The peripheral initialization is done through HAL_PPP_Init() while th...
STM32 SPI 16 bit transfer with a 32 bit Slave device
Hello, I had a general inquiry about using SPI. We are trying to use the STM32F446xC as the microcontroller to control a SPI-to-CAN controller (TCAN4550) which does 32 bit transfers. The microcontroller can only perform 8 or 16 bit transfers through ...
STM32H7 Complementary PWM: Issue on CHxN
Hello,I am trying to generate a complementary PWM with a timer in my STM32H723VGTx, I configured channel 1 on timer 1 with the PWM Generation CH1 CH1N mode.I set all the parameters of the base timer and the value for the pulse of PWM, but during the ...
