I have a STM32L432 Nucleo-32 board and I'm trying to use ITM printf trace. I created new project with configuration: "Targeted Project type: Empty" "targeted language: C++". I'm not using HAL libraries.In the syscalls.c I added following code://Debug...
Hello everyone,I am currently working on a project using an STM32H755ZIT6 MCU and want to use the USB CDC class to send data over USB. I can successfully program the MCU and the system clock configuration is correct. However, when I plug in the USB, ...
I'm having difficulties in approaching GPDMA in H5 architecture. In another thread I'm trying to run a DMA, which keeps going itself (circularly?).Does that mean inherently that always a linked list has to be used?And would uneviteably go along with ...
Recently I’ve been developing a host application on a Mac Mini (Apple M4, Sequoia 15.5) using Xcode. It communicates with a STM32H7 board via USB CDC, using the internal PHY at 12 Mbps. The USB CDC code is auto-generated by CubeMX with all default pa...
Hi, I assume there have already been posts on this topic, but I can't handle this problem. I have an STM32F429I-DISC1 board and I'm trying to connect it as a USB HID keyboard. Unfortunately, all the guides and articles don't work, and my board isn't ...
Hi, I'm working on STM32H7A3NIH6Firmware Package: STM32Cube FW_H7 V1.11.2 I have a very interesting issue with bootloader jumping.According to the file "an2606-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics", the bootloader address ...
I have an STM32H735 Discovery Kit and am running the example LWIP code from STM32H7-LwIP-Examples/STM32H735_Disco_ETH. This works great. But, when I add MDNS, I get a very curious crash.I enabled MDNS in CubeMX, and then created a new thread to wait ...
HiI'm having troubles programming the stm32h755zit6 on my selfmade PCB. The schematics should be right, as i am able to programm the STM32. But if i run a simple code inwhich a certain pin should be pulled up high, it just won't work. Therefore I tho...
Problem DescriptionI am having some trouble using HAL_UART_Receive_IT() to receive UART data in interrupt mode, the callback HAL_UART_RxCpltCallback() only triggers once for the first byte, subsequent bytes do not trigger the interrupt. I don't know ...
I am trying to switch the USB to DisplayPort mode via the PD (Power Delivery) line. I have a custom board based on the STM32G0B1CBT6, and another board based on the RTD2556, which works well for switching. I am sniffing PD communication using the LA1...
