Hi everyone,I'm a beginner, and this might be a basic question for many of you, but I appreciate your help nonetheless.I'm working on a project using the STM32H723VGH6 (due to size and design constraints, I can't use the ZG series) and I want to expa...
I am using a pin to Switch on the power supply once the MCU is powered.When powering up the MCU I am getting a Glitch before it turns on the MC GPIO configuaration is given below. For every output I am getting a glich before it SET from RESET Can a...
Hi,I have enabled option bit SRAMxECC is in FLASH_OPTR by following sequence mentioned in datasheet to enable SRAM ECC, However RAMCFG_MxCR ECCE still shows as 0(disabled). Please do the needuful.
Hi,I want to use BC1.2 protocol of STM32G473CE MCU. But STM32G473CE supports USB PD also. So in order to use only BC1.2 can I use only Dp Dm lines of STM32G473CE and leave CC lines un-connectedAlso what is the maximum power negotiation performed by S...
I'm trying to set the QUADSPI FIFO threshold when reading from external flash using interrupts and I want an interrupt to occur when there are 32 valid bytes in the FIFO. I'm setting the QUADSPI_CR_FTHRES to 31 according to the datasheet but when I l...
Hi all! I have been using a F446RE board to communicate with an encoder using SPI. I get back a 16-bit value every ms (the process runs at 1kHz). However, I now need to transfer the acquired data over ethernet (it has to be ethernet, not UART or anot...
This is regarding the UART1 and UART2. 1. I am trying to learn how UART works by communicating between STM32 and ESP32. I am able to send data from STM32 to ESP32 and it works. However, when I do the same from ESP32 to STM32, for some reason I cannot...
Hello,I am running the code as shown in the attached file and I get two different behaviours on to identical stm32h735g-dk boards. One of the boards will send exactly 37 can messages when the button for master is clicked and the other board will send...
Hello,I am trying to route printf-like data streamed from the SWO pin of an STM32L432KB MCU to a Windows command prompt using a STLINK-V3SET/MINI probe. I need to do this while flashing new firmware or debugging. The SWO pin uses UART encoding at 2 M...
Hi ST tesam,When I use the HAL of STM32C031, I have some trouble about SMBus.Q1:When I use the SMBus of STM32C031 series. If I do not got the feedback from the slave, sometimes the SDA will pull down(similar to the yellow line show as below) and syst...
