Hi all, I have what's probably a niche problem but a problem (seemingly) nonetheless. I'm making a CANBus application that I'd like to use DAR (Disable Auto-Retransmit) mode for. I'm running into an issue where, after a certain amount of time while t...
Hi all.I'd like to know if STM32L4S5 and STM32L432 support SWD multi drop (SW-DP v.2 protocol).Thank you in advance.Best regards,P.
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.
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...
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...
the below code is not working for me //HAL_TIM_PWM_Start(&htim15,TIM_CHANNEL_1);HAL_TIMEx_PWMN_Start(&htim15,TIM_CHANNEL_1);
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 ==...
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 ...
