Hello, everybody.I'm working in a circuit design whose main task should be to read an µSDHC card and copy its files to the computer. I'm using SMT32L073RZ with SPI (µSD to MCU) and full-speed USB (MCU to PC) communication interfaces.The other feature...
Posted on May 04, 2018 at 11:24Hi,I found a bug in the quad spi driver for stm32l4xx. In the function HAL_QSPI_Receive_IT, the interrupts flags must be cleared before start transfer otherwise flag TC could be missed:- WRITE_REG(hqspi->Instance->AR,...
Hi everybody,I created a project for using the STM32F746 DISCOVERY board with LwIP utility (see image 1 and Image 2). As soon as the project gets created i tried to build it, but ended up not beeing able to do so and getting the error shown in image...
I am using USB Virtual Com Port with CubeMX on a STM32F4 controller.The problem is, that occasionally, but increasingly often I cannot open the COM Port to my Device. It is very hard to reproduce, as changes in completely different code regions can c...
Hi ,I am using STM32L series of MCU.From the application code independent watchdog is used and when it is time for entering bootloader say due to firmware upgrade, i use while(1) to reset the system.1.Once inside bootloader I am observing that the bo...
Hi there,i have Projects where I used USB FS for COM Port Communication. How can i change them to USB HS do i need to change the clock or other settings?Thanks in advance.I am new with STM32
Hi all,The ADC on my STM32F303 doesn't want to run. I'm trying to measure 8 input channels via DMA with TIM7 as the ADC trigger. Having had a thorough read of the examples in the repo for Cube, my setup should work but it doesn't. The values never ch...
Hi all,I still have trouble connecting my 2 STM32H7 in USART Synchronous mode. When receiving a message in Interrupt or DMA mode ( I don't need to transmit something) I always get Error Code x11 = Underrun Error. As I understood this is due to the f...
