I am using STM32F103C8 board and CubeMX to create the code. I have connected the M66 to STM32 to UART2 port. I try to send some commands to Quectel M66 via STM32's UART port. It receives the command but throws some junk characters. I have set the bau...
Hi there,I am developing a bootloader + application architecture for both serial and OTA programming. I have managed to get this working, the bootloader is able to program the application into flash, check the CRC, set the VTOR, etc. and then jump in...
The test procedure. Connect with server_1(set reuseable address), and close. (when I set reuseable address, the set error is happened) 2.Reconnect with server_1, but connection error has occupied. =>I wonder why I set reuseable addr...
I'm reading AN3411, and section 4.4 details how to compute the values for the time stamp unit registers.It shows two equations under Equation 1:tick = ((increment * 10^9) / 2^31) and the other is corrupted (typo?): Adden(d * increment) = 2^63/SysClkI...
Hi, I'm trying to transfer a text file via USB cable from the PC to my development board (stm3210-c), I generated the project with CubeMx, my board is configured as a device and I loaded the virtual com port as a Class for FS IP.Now when I try to tra...
We have some older chips that are trying to program on board via another processor. I have been using AN3155 and can read from the processor and can write areas in memory that are set to 0xFF. I have verified by snooping on the UART that the correct ...
Hello All This is my first try of Vcom ; I can trasmit to PC but I cant receive from PC ; /* Init Device Library */ USBD_Init(&USBD_Device, &VCP_Desc, 0); /* Add Supported Class */ USBD_RegisterClass(&USBD_Device, USBD_CDC_CLASS); /* Ad...
i want implement us delay Delay_us(uint32_t time) function in my application without using timer Hal_Delay() function minimum delay 1ms how can i generate us delay?
Dear,There is probably an error in the STM32F1xx CubeMX library V1.7.0.In the "stm32f1xx_hal_can.c" in the "Legacy" folder, the preprocessor compilation (ligne 117) is "#ifdef HAL_CAN_MODULE_ENABLED" but I think it must be "#ifdef HAL_CAN_LEGACY_MODU...
I am trying to update the firmware of an STM32F446RE Nucleo board with Raspberry Pi using usb-dfu protocol using dfu-util library. I want to leave the bootloader mode without actually pressing the reset button on the STM board. How can I do it? Can I...
