Resolved! Clock Configuration Issue for Sound Acquisition with STM32G473VET6 and IMP34DT05TR
Hello,I am currently working on a sound acquisition project using the STM32G473VET6 microcontroller and IMP34DT05TR microphone. I am encountering an issue while trying to configure the Serial Audio Interface (SAI) clock frequency. My target frequency...
Resolved! Stm32F446 RM error?
I noticed, that in the RM for the stm32f446 (v6, 2021) the description for the number of slots in the SAI peripheral (NBSLOT) seems wrong?I am not quite sure, but the behavior on my device suggests that the bitfield represents the number of slots -1....
No device found on target (SWD connection)
Hi Community,Prelude: I soldered my first PCB, added STM32H743ZIT6, decoupling capacitors, BOOT0 switch, NRST with resistor to ground, 5V->3.3V LDO, powered up by USB and 4-pins SWD for debug (PA13/DEBUG_JTMS-SWDIO and PA14/DEBUG_JTCK-SWCLK pins). Ch...
RESOLVED: Changing TIM PWM pulse width on the fly
Posted on October 14, 2016 at 01:13Hello, I am using STM32F4 Discovery board (with STM32F407VGTx) with the latest HAL libraries. I am interested in varying PWM pulse width (duty ratio) in a while loop. Looking at MX_TIM3_Init function (also attached...

Getting continuous interrupts on USART
Hello Folks,I am working on STM32F1 series controller where we receive data on usart and perform actions accordingly. Few days back ,my system was getting rebooted due to watch dog timer. After debugging the issue,it was found that when i receive som...
Resolved! HAL_UART_Transmit_DMA issues | STM32F3
Currently I am working on UART DMA and I encountered problems after transmitting data via DMA UART. After 1 successful data transmission, the state flag remains on BUSY. After a search, I ended up on this thread and this fixed the problem. Threadstat...
STM32L431 bootloader Not switching to application
I am working on STM32L431RCT6 microcontroller. Similar changes tried on STM32L053C8T6 also.Using custom hardware for product development and hardware is validated. I facing issue, bootloader not jumping to application. Instead it's creating hardfault...
Resolved! I believe there is a bug in HAL_ADC_ConfigChannel(). Using the STM32g071, with ADC_SCAN_SEQ_FIXED, ADC_EOC_SINGLE_CONV, and NbrOfConversion == 1, when HAL_ADC_ConfigChannel() is called, it OR's in the new channel number, which is incorrect.
