Hello ,I Have configured STM32G030K6t6 MCU has SPI master . I have used SPI2 Module. Chip select is controlled manually by GPIO .I am unable to write exact data 0x79 in SPI2->DR register . Always it writes 0xff to DR and i am unable to read/Write an...
Resolved! STM32H743 CANBus TX Timing
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...
Resolved! SWD multi drop support on STM32L4
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.
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 ...
