Hi all, I have two stm32l476RG nucleo boards connected via transceivers. Each of them works fine in loopback mode. however none receives messages of the other in CAN_MODE_NORMAL. I'm using a simplistic code ported from STM32L476G-EVAL HAL examples...
HI Currently, i am working with stm32f207zg .i want build mqtt on these mcu using Ethernet didnt understand where to start.I am new in Ethernet.can i use cubemx tools for that?
Hello all,I am using STM32F407 , in that i am able to communicate with USB Full speed mode. In that i am trying to send data serially from android phone which act as a Host and STM32F407 act as Device. When i trying to send 2KB data serially to my US...
I'm trying USB_CDC FS (Full Speed) on STM32F072C8 Controller. I'm able to Transmit data larger than 64 bytes to PC, but not able to receive data more than 64 bytes.I'm using CDC_Receive_FS function for receiving and buffer size is 1000.If i send 100 ...
I'm trying to use HAL_SPI_Abort() os SPI2 interface in DMA mode for STM32F769NI MCU and program hangs in it in loop: while (hspi->State != HAL_SPI_STATE_ABORT)So it seams that State should be changed in interrupts, I think that in SPI2_IRQn interrupt...
Hello,HAL contains both HAL_SRAM_Init and HAL_NOR_Init.But what if we have additional memory in PSRAM (FPGA device in our case).If we register the additional interface with HAL_SRAM_Init , it will call HAL_SRAM_MspInit again , and register again with...
Hello. I have custom board with STM32H743 and USB3320 in Full Speed Mode. Dont have problem with initialization of MSC (Window read descriptor, configuration and other). But when read blocks from SD card some trouble occurs. With USBPcam and Wireshar...
HiI use the STM32L452 which is configured as a USB CDC device using CubeMX. The device is used as a "gateway" that connects a linux host to a CAN bus system (essentially a USB-to-CAN adapter). The linux host configures the USB device as an SLCAN base...
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,...
