Hello,I'm a bit confused to how use the VREFBUF on this MCU.I want to use the internal voltage reference (SCALE 0 : 2.5V) for better ADC accuracy.Do I have to connect the VREF+ pin (20) to AVDD (+3.3V) or I've to connect it to a 1uF + 100nF capacitor...
Hi,I have a test app for the U5, which is intended to sleep for a short period of time and wake for a short period time, not unlike the default PCC Sequence you can see in the CubeIDE IOC. It will toggle an output line when entering STOP3 mode and al...
Hello, I have configured SPI Slave Receive only with Circular DMA, and I can receive data fine. My problem is that I want to have the current receive index on the SPI DMA Buffer when I receive an external interrupt I try to use StreamIndex but it sh...
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...
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...
