Hi,I'm trying to trig a DMA from the EXTI0 input. There is a good example in the STM32Cube package for the H7: Projects\STM32H743I-EVAL\Examples\DMA\DMAMUX_RequestGenBut this example uses the BDMA and I need to use the DMA1. I tried to make some modi...
Hi all:If I plug in USB 2.0 mode high speed port(PC recognition Windows7), frequently enter the ISO in/out incomplete interrupt. but if I plug in USB1.0 mode full speed port,is OK. Once enter the incomplete interrupt.record or playback, audio will b...
I am working on USB CDC ACM device. I want to communicate with High Speed device using full speed host(NUCLEO-F411RE). As I am new to USB protocol, but I know that device starts communication in FS mode and switch to HS mode only if host respond to J...
void main() { ***_Init(); MX_USB_DEVICE_Init(); uint8_t[4] ={0x00, 0x00, 0x00, 0x00};//{button, x, y, wheel} while(1) { UsbFlag = USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, &Buffr, sizeof(Buffr)); } }this work no proble...
Hi Everyone,I am trying to run HRTIM Master unit with repetition interrupt and the repetition counter is 1. Now, when I am in interrupt I have to update compare and period registers and using LL to do so. But, within interrupt merely updating registe...
The software almost finishes download and then quits with forbidden. This is using chrome on Windows 10. I am trying to learn the F767ZI that I just received. Ideas?
I have created a project in STM32CubeIDE with UART and some GPIO's as Input and Output.I have created 2 Tasks using FreeRTOS - CMSIS v1(osPriorityNormal, osPriorityBelowNormal) with different osDelay(osDelay(500);, osDelay(600);). I have compiled and...
Hi,We are developing products using STM32F746ZE. We have a requirement for fashing the device using on-chip bootloader over CAN interface. We found tools(FLASHER-STM32) on the ST website, which can be used for flashing through UART.Similarly, for the...
Hello,We are interesting STA8090WG as they support both CAN and GPS.However, after simply review with data sheet, I have some questionsIs it right ? Once we use CAN, we can't use USB since those are alternated with same pin.Can we get reference schem...
I try use systick handler in STM32G0 uC, i use LL libray. In funcion to activate Systick ( void LL_InitTick(uint32_t HCLKFrequency, uint32_t Ticks) ) is a bug.The error consists in incorrect setting of the SysTick-> CTRL (STK_CSR) configuration regis...
