I have a UART configured in DMA read mode:/* task 1 code*/ uint8_t dmaRXBuffer[1]; HAL_UART_Receive_DMA(&UART_DOWN_USB_TO_SERIAL, dmaRXBuffer, 1); /* UART DMA receive complete ISR code*/ void HAL_UART_RxCpltCallback(UART_HandleTypeDef* huart) { if...
I have a STM32F756 on my PCB. The microcontroller was responding with no problems, has been programmed and software running on it. It was put to the side for a few days, and when picked up again, the micro has become unresponsive and the SEGGER JLink...
I am using an STM32L476VG which does not have UART transmit/receive fifo's.Therefor I am using DMA for periodic transmission of some data (3 bytes at 125kbit at about 2kHz).This is all configured in CubeMX and functioning (DMA in normal mode btw).I a...
Hi,I am trying to setup clock from HSE on a F401RET6, when I setup 48MHz it works fine, but when I try 84Mhz after few steps when clock is set the CPU makes werid things (the PC counter stops increment or goes to a strange value).I am using libopencm...
STM32 ST-LINK (ST-LINK>>Firmware Update) complains about ST-Link not being in DFU (direct firmware update) mode.
Hi I bought the STM32F091C-Eval board to practice for µC programming. But it seems i have never programmed anx µC and I am looking now for step for step µC programming for the STM32F091C-Eval. I downlaod the STMCube and ARM MDK for the programming an...
What values should OTG_HCFG & OTG_HFIR (and USBPHYC_TUNE for internal HS PHY on STM32F7x3xx) be set to for Isochronous data?As I understand it Isochronous data should be allocated 1 to 3 'slots' per Start of Frame (SOF) in full speed mode and up to 1...
Hi,I just buy this eval Board and I am new in the world of MCU-Programming. For the board i bought they were not any document about how to use it. I install the MDK 5 ARM and wish to go stepwise through configuration and programming of the board.Any ...
