Hello, I'm attempting to flash firmware to aforementioned microcontroller using STM32CubeProgrammer. I have connected ST-Link VCP port to PA2 and PA3 ports, and i can communicate with my application fine. I even erased flash memory so I could be sure...
This is the data I recorded with WireShark. As shown in the picture, when I send HID packet once (len=91), the USB will send empty data packets indefinitely (len=27), then trying to send packets from host to device (out direction) will cause the tran...
I was getting strange results with the deadtime prescaler of the H7 hrtim and it appears that the H7 reference manual (RM0433 rev 7) is incorrect: The DTPRSC field of register HRTIM_DTxR, is supposed to get binary values from 011 to 111 (000 to 010...
Hi,I am using RTC with LSE (32.768Khz) in my product, and I programed RTC wakeup timer to 5min by calling HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 300, RTC_WAKEUPCLOCK_CK_SPRE_16BITS);It works perfectly on my test machine, but it will not trigger on my cu...
I am trying to implement a cdc device and would also like to use the FreeRTOS. For code generation I use CubeMX. To keep the interrupt of the receives as short as possible I want to send the answer to the host using a task. But after a few seconds my...
Hi,I am new to HAL libraries and currently working on a small CAN bus consisting of two STM32F4-discovery boards connected to a CAN transceiver connected to the bus. Both transceivers are externally powered with 5V.So far, I tried the existing CAN ex...
I got my SPI5 running the way I want it but now I want to move to DMA. When I do this the SPI lines remain low after sending its data. So I assume my config is off. Using the IOC to make changes I only see the fowling added. /* SPI5 DMA Init */ ...
How configure port ,how get _port_status work,
char *data = "Hello World"; while (1) { HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin); HAL_Delay(1000); CDC_Transmit_FS((uint8_t*)data,strlen(data)); }uint8_t CDC_Transmit_FS(uint8_t* Buf, uint16_t Len) { uint8_t result = USBD...
