Hello everyone,I am trying to use USB on the STM32 NUCLEO-L4RZI-P dev board to work as a Communication device class (CDC).I have initialized the USB using the Cube IDE.After initializing, I tried sending data using the " CDC_Transmit_FS( buffer, size...
My mcu is H743, the MDMA is enable for SD. The FATFS is used to operate file system. CubeMX is used to generate template code.Without the FreeRTOS, both of the FATFS functions f_write() and f_read () work correctly. But when the FreeRTOS is used, f_w...
As part of my thesis, trying to get as much data transfer from PC to STM32 as possible. As I am going to transfer a video stream, isonchronous transmission seems to be a good choice, but I don't know how to do it properly.I use STM32H743 microcontrol...
Hi there!I installed the tools for the workshop just as in the 00-Azure-RTOS-WS-prerequisities-homework.pdf. I am able to create the Tx_Thread_Creation example, i can download and start it on the Nucleo board. I can even debug it. But: LD1 does not b...
Hello.I am using STM32H7, with USBD CDC HAL Driver.I created a firmware that works as follows: The first one I got from the PC, via USB, JPEG , then I decode it to YUV, then using DMA2D to RGB and then display it using LTDC. Everything works great fo...
I use STM32H723VET6. Bootloader ver 9.2. When I can send command GO at FDCAN (PD1, PD0), I receive ACK(0x79), but after that MCU is fail.My function:void BootCanGo(uint8_t* answer){ uint32_t Delayer = 0x8FFFFF; uint8_t SendedData...
Hi guys, looks after using "portYIELD_FROM_ISR(pxHigherPriorityTaskWoken);" the program gets thrown into this PORT: ARM_CM7 HEAP: HEAP4 .section .text.Default_Handler,"ax",%progbits Default_Handler: Infinite_Loop: b Infinite_Loop .size Default...
Hi,I am trying to configure the USB OTG of my Nucleo-L4R5ZI board to host-only mode, but I am facing some issues. In the user manual is said that "A green LED LD8 lits up in one of these cases: (1) Power switch (U12) is ON and STM32 Nucleo-144 board ...
Could we create a hi-fi audio project base on STM32L series?What series can be used?
Hi everyone, first time using freeRTOS and everything is working besides context switching from an ISR.The STM32H743ZI has DMA (DMA1_Stream0) setup as UART Rx. This triggers an ISR that sends a queue for task synchronization, as the task that receive...
