Hello.I try init CAN bus. My CAN transmitter is MCP2551.Connecting:RX -> nucleoPB8TX -> nucleo PB9RS -> -----| 10K |----- GNDCANH - CANL 120R betweenVss - GNDVdd - +5VFirst step is: init GPIOvoid CAN_gpio(void) { LL_AHB1_GRP1_EnableClock(LL_AHB1_G...
WHEN USED CIRCULAR DMA NO HAVE PROBLEM BOUT IF USED NORMAL DMA AFTER SEND BUFER NEXT TIME WHEN ENABLE DMA STRIM BIT NEW TRANSFER NOT WORK IN RECIVED MODE EXACTLY SAME ONLY RECIVED ONE TIME
Hello all, I'm building a system that I'd like to run at 1.8V with an STM32H7 and USB high speed PHY.I have a few questions, so I'll just jump right in:1) Will the STM32H7 core run at 400MHz when powered by VDD=1.8V? Some MCUs can't run as fast ...
Hi there,I am transmitting and receiving data via uart like an pl2303 bridge via USB FS. How can i manage the transmitting and receiving process outside the while so that i not block the mcu?int main(void) { USB_CDC_STATUS_t check_usb; uint16_t r...
I need to transfer parallel data via GPIO and DMA. The microprocessor I use is STM32F103C8I need to transfer some memory data to GPIO quickly. I've written an init code using STM32F103 and the HAL library. But DMA doesn't work. At the end of the proc...
I have problems to get the example code running, few functions aren't known. I changed them to HAL-functions which were written (nearly) the same. But the Code fails just in the beginning. At the moment I try to erase the on-board external flash. Is ...
To put it another way, when would I want to use STM32CubeMX over STM32CubeF3/F4/F7 when working with F3/F4/F7 Discovery boards?
I need a STM32F411 DISCO USB Host example using FreeRTOS.My project is based on STM32F401. I don't have target hardware yet & have survived with a NUCLEO 401 and linking wire. That won't be good enough for USB.Nearest is a STM32F411 DISCO but my rush...
