SPI always calling callback

Hello to everyone. I'm creating a project where i need to communicate via SPI. My main board, is configured as full duplex Master, and i have other STM working as full duplex slave. But, i have a problem. If i configure the boards to just have one fu...

To measure Sine wave Voltage and Frequency directly with help of MCU STM32F030CC.

I want to measure AC signal voltage and frequency .Presently i am using function generator to generate sine wave having 3Vpp(peak to peak Voltage) and feed directly to MCU pin which support ADC channel(Channel 7).So any one can guide on this.I have i...

Use HAL_SPI_Receive_DMA receive data. Sometimes the received data shift 3 bytes. Why? The board is STM32F750, build as SPI slave.

SPI slave receives data of unknow size.When SPI master gives a rising edge, SPI slave detects the rising edge and starts HAL_SPI_Receive_DMA(define a large size amount of data to be received). When SPI master gives a falling edge, SPI slave detects t...

When will the ST microcontrollers (STM32F4/F7/H7 series) be available again?

For some time, microcontrollers ST have not been available on the market. The lead time is of the order of 6-8 months. Suppliers do not guarantee deliveries. When will the situation return to normal?Thanks.

ADC + DMA convCplt and convHalfCplt

Hi,I am trying to use a circular DMA to transfer ADC samples on STM32L4R9VI.I configured a 3.2 Msps sampling frequency, which means that HAL_ADC_ConvCpltCallback and HAL_ADC_ConvHalfCpltCallback must be called each 10 ms for a 64000 elemets buffer.Ho...

RTC in STM32F302VE MCU Occasionally reset to initialize configuration time.

Hi all,Our product is build upon STM32F302VE MCU with ECX-34R (32.768KHz) crystal oscillator connected to PC14-OSC32_IN & PC15-OSC32_OUT and Panasonic CR1220 (3V) battery connected to VBAT.We configured the RTC via CubeMX and used RTC_BKP_DR0 registe...

What type of tranistors is used as power switches in the P-NUCLEO-IHM001? I found that for some other ST-family there are MOSFETs but can't find any information about the transistors in the STM32. If they are MOSFETs, are they NMOS or PMOS?

F767zi UART

I tried 2 demo printf using HAL and UART Tx using LL from your examples. LL demo runs ok and getting message display on Serial COM console. HAL printf demo got not message display. Any suggestion? I hv another board NUCLEO-F411RE works ok for HAL UAR...

STM32F205,UART DMA transfer stuck after a while

Hello to everyone,Thank's to the people who will take time to read my problem.To be short, I'm working on a system which embed a STM32F205 MCU. This system can communicate with other similar systems by exchanging UART messages over an RS485 physical ...
