I am trying to configure the STM32L4A6 to act as an I2C slave on its I2C3 peripheral (PB4 - SDA, PC0 - SCL) with 7-bit addressing (address 0x42). The master is a Raspberry Pi CM4 configured on a software-defined I2C bus (i2c5, using GPIO10/11).Both d...
Hello, I have an STM32G474VEH6 and we have the main function running a code at 20kHz that takes almost all the period to be executed. We also use ADC and PWM synchronised to convert at the period start. Now we also have to read a 64bit SPI slave in m...

I’m looking for comprehensive materials and guides on setting up BLE P2P router profile for STM32WB55 microcontroller.I need more detailed instructions than those provided in the official documentation (https://wiki.st.com/stm32mcu/wiki/Connectivity:...
Hello, I am trying to use SPI with the STM32H7A3RGT6 microcontroller to send and receive data. However, I am not sure if I have created my functions correctly, or if I have properly configured the registers to achieve full-duplex SPI functionality. H...
Hi,I am starting to implement USB PD Sink application and i run into issue.I followed the AN5418.Seems the BSP_PWR_VBUSGetVoltage is Obsolete and i did not find any info how to implement it in alternative way. Found some posts that hint this might be...
Hi!I'm working with STM32CubeIDE and I want to send data via UART using the code below. char *msg = "Hello\n"; HAL_UART_Transmit(&huart6, (uint8_t *) msg, strlen(msg), 100); But I get an error like this:What can I do about this issue?
Hi all, I use UART8 of the STM32F732VE with 921600bps. And I want to use UART rx dma with RTO interrupt in the following sequence. 1. __HAL_UART_ENABLE_IT(&huart8, UART_IT_RTO)//interrupt enable 2. huart8.Instance->RTOR = 0xff00 //set timeout 3. HAL...
Hi All,I am having difficulties getting both HEXSPI PSRAM (XSPI1) and OCTOSPI (XSPI2) running at the same time in a memory mapped mode on STM32H7S78-DK board.There are two examples for this board:XSPI_PSRAM_MemoryMapped that configures XSPI1 in memor...
Hi Team, Currently I am working with STM32U575ZiTx SOC and I am using Tim3 for counting external clock pulses, Can you guide me with the code please. Below is my requirement : 1. What is the maximum frequency of the incoming signal? (To ensure the t...
