Every period of time i send ~33bytes through USB CDC, if suddenly USB cable disconnected and reconnect i get 16 bytes of the last message loaded, and then continue to get new messages.How can i detect disconnection and were these 16 bytes located?
Hi,I am currently working on a resource-hungry project which requires a lot of memory for storing various buffers and RTOS threads stacks and objects. We are using the STM32L476 controller with Keil uVersion 5.34 IDE and Keil RTX5 as RTOS (CMSISv2) f...
hi,i am trying to run mcp2515 with stm32f303k8 board i am successfully done with Hal but when trying the same function in LL it data register is get some garbage value all time.attached is my code nd logic analyzer imageI have make sure that transmit...
I'm despairing of ever getting 4-bit SDIO FATFS working on a 144-pin H7. I've tried modifying example code for the various eval and discovery boards, building from scratch with CubeMX, etc. and nothing works. The HAL code seems to read the card detai...
As I have seen, an open bootloader middleware is offered for the STM32G4. An FDCAN implementation can be found here. Are there any plans to also offer a pure CAN implementation?I am also interested in whether it is possible to program directly via CA...
Hi all,I am working with a stm32f7508dk. My code is running XIP on 1-bank QSPI.Here is the MEMORY definitions in my linker file: MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320K /* FLASH (rx) : ORIGIN = 0x8000000, LENGTH ...
unplug my CDC USB output cable and sprintf( string, "%.2f ",myFloat); will crash plug it back in to the PC and without any comms, it works.could it be a memory leak if the CDC driver is not handshook ?anyhow the CUBE didn't allocate enough Stack ...
Hello ST community,I use ADC3, 4 and 5 of STM32G474 and configure them to ADC3/4 dual mode, ADC5 standalone (no other option in CubeMx). HAL function HAL_ADC_Start_DMA fail for ADC5 , because it check if it is in correct mode of ADC3 master. So ther...
I am using STM32G0B1KCT6Clock Configurations as like thatAnd pin configurations are like that I generated code and run to debug. When i connected the MCU to USB port at PC, There is a error message "USB not recognized". I changed the usb_cdc.c at 516...
Hello all, I'm pretty stuck and could use a pointer in the right direction. I have a nucleo communicating with another board via UART. I would like to be able to update the application on the nucleo board via UART from the other board. Is there any ...
