I'm communicating between STM32F746G-Discovery ans ESP32 using UART (PC6 and PC7 pins on STM). ESP receives some data at certain intervals over WiFi and transmits it to STM via UART. On STM I want UART to receive data only when ESP32 has transmitted....
I am trying to configure 32F469IDISCOVERY board for display application. I have referred article : https://community.st.com/s/article/FAQ-GUI-on-STM32F469-Discovery-boards-using-CubeMX-and-STemWin.In that I can configure display in a landscape mode. ...
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...
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...
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...
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.
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...
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...
