We use STM32F479 for portable measurement device (with TouchGfX HMI, data is stored on quadspi flash also). We have a USB host interface where we can read and write data to an USB stick.Now we would like to send an USB stick to the customer in order ...
Trying to figure out how to launch the STM32F100 UART bootloader from within an application and have been having zero success after careful review AN2606 Rev 46 “STM32 microcontroller system memory boot mode�? and AN3155 Rev 13 “USART protocol used i...
Posted on November 23, 2017 at 13:09Hi everyone,I'm developing an HID Host application to comunicate with a own device and I'm using the NUCLEO-F446ZE board.At the start I tried to use the HID_Standalone application in the STM32CubeF4 firmware packa...
Hi there,I am trying to make my STM32L562 Discovery Kit an USB device to read and write files in a SD card as a mass storage device.Can anyone tell me if it is effectively possible with this board? If yes, how can I do it?I have tried different setti...
Hello everyone,I would like to ask for some guidance on which Interrupt i should use for FreeRTOS message queue to help synchronize my state machine. I am using UART to transmit data to device, and i would like to know if i have finished transmitting...
On first debug session everything works fine. However on second and beyond session dma stop working.Hardware: custom stm32l4p5cet based board, original ft232 uart bridge, stlink v2.CubeMX settings: UART with DMA on RX and TX (RX in circular mode), Gl...
Are there any instructions/app notes discussing the steps required for a SPI transfer using DMA and the LL libraries? I found some samples online for UART and tried adapting them for SPI but am so far unsuccessful. I'm still debugging but in the mean...
