Hi,I want to setup USART3 TX transfers using GPDMA, however, without success.For such purpose I also followed this article: https://community.st.com/t5/stm32-mcus/how-to-configure-the-gpdma/ta-p/49412STM32CubeMX setup is:USART TX DMA ChanThe code for...
Hello everyone,I am generating PWM signals using the HRTIM module. Specifically, I am using Timer D to generate a PWM signal along with its complementary signal. This signal is always in phase with the master counter, setting at the timer period and ...
how to access RTC in "TFM\TFM_Appli\NonSecure"? Could you share an example?
Hi, I am working on STM32WB55RG MCU and I wanted to enable one pin for Wakeup from Shutdown mode. That works fine. But, when another EXTI pin is initialized, I am not able to disable it. The MCU wakes up when this pin (connector) state is changed, ev...
Initially, there was CubeIDE project for STM32H747XI without TouchGFX and without C++ accordingly. Everything was ok, startup, linker or HAL init sequence were not touched. Everything worked (DSI, LTDC, I2C, etc.)Time later, I added TouchGFX into pro...
Hello,I am designing a system to interface an ADC via SPI and send data through the USB (VCP) to a PC.I tested the flow using NUCLEO-H7S3L8, and everything was working fine so i moved to the design of a PCB.When uploading the same code i used on the ...
Hi all, I am currently using the STM32F0 MCU. I would like to understand how errors are handled when the CAN bus triggers errors. Specifically, how is the error handling process for each error category implemented? Additionally, how can the system re...
Hi :waving_hand:, I am designing a midi controller. I want test out using an STM30 MCU, I was wondering if anyone could suggest dev board/ processor? I don't want or need wireless communication (wifi and Bluetooth)I want to run a lot of linier poten...
hi , Am in Project topic migrate Project from stm32l476re to B-U585I-IOT02A for Apply trust zone for the Project the problème itsa first time Try use STM and i get problème like stm32l476re have LCD ingrate and B-U585I-IOT02A no . So any one can he...
Greetings! I am using STM32 for a very first time. I made my custom PCB with 10MHz oscillator. In the Clock Configuration window I have sellected the PLL and the HCLK is set to 80MHz (max for the uC). The outputs are all 80MHz. So I made a simple bli...
