Hello ST Community,I'm facing a MIPI DSI configuration issue with my STM32U5A9 and TFT LCD. When using PHY DSI as the DSI lane byte clock source, my code fails with a timeout on HAL_DSI_ShortWrite. When I switch to PLL3P, the initialization proceeds,...

Hello Community,I’m facing an issue with Pin PC15 on my board. I am unable to configure or use it as a GPIO, either as input or output. I’ve tried basic initialization, but it doesn’t seem to respond as expected.Has anyone experienced a similar issue...
Hi all,I am experimenting with H7 ADC (after having tried the G4 ADC).I see in the HAL that the calibration, HAL_ADCEx_Calibration_Start(), for H7 MCU wants a parameter more than G4. One should specify ADC_CALIB_OFFSET or ADC_CALIB_OFFSET_LINEARITY.I...
I saw a strange behavior when using STM32F401RBTx, to show you I added only 1 output as LED and toggled it. I have just that much code. I tried with 16 MHz, 48 MHz, 64 MHz, 84 MHz. It went hard fault when speed is 64 MHz or 84 MHz. This is th...
Hi ST expertI'm ready to use STM32G473CBUx now. According to the datasheet, the STM32G473CBUx does not have an analog ground VSSA, only a ground VSS. I have questions:1. The analog input of the internal ADC/DAC is referenced to the chip's VSS, or has...
Hello everyone! Recently, I have been developing a firmware product based on STM32H750, using FreeRTOS and LwIP. Because the application scenarios for this product frequently involve large volumes of broadcase messages, while the product's own commu...
I am implementing a system with two STM32H753 microcontrollers. MCU1 reads ADC data and sends it over UART to MCU2 using UART DMA on ADC conversion. MCU2 reads data from UART via DMA and is supposed to do some filtering (among other things) to the re...
Hello, We're working on a custom board for the STM32H750IBX. Our boards arrived. The first time, the chip was installed poorly and shorted out. We assembled a new board at the SMT factory with the new chip, but we still can't connect to the chip to p...
Hello,in Application Note AN6228 it is stated, that it is possible to perform write-operations on the external flash while running code in memory-mapped mode (Execute-In-Place XIP) on the same external flash memory (on a different bank).See:https://w...
