Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
In the STM32F303 datasheet is written that "no external termination series resistor are required on USB_D+ and USB_D-, the matching impedance is already included in the embedded driver." However, if I look at the STM32F3DISCOVERY board I see 22 Ohm t...
I want to connect a STM32F429ZI Nucleo board to a PC using an ethernet cable, but without using a router to bridge them. The Nucleo would have static IP and the computer would be a client connecting to it. How would I start going about this? I've don...
I am using DFU to load my application code in to target board, I can be able to convert application build in to dfu build and also be able to load using DfuSe tool in to my target board.I want to enable the ROP (level-1) in STM32, for that I need to ...
Hi,I have noticed change in HAL_I2C_EV_IRQHandler that breaks I2C communication.In STM32Cube_FW_F4_V1.23.0 in stm32f4xx_hal_i2c.c@3379if((sr2itflags & I2C_FLAG_TRA) != RESET)was changed to else if (I2C_CHECK_FLAG(sr2itflags, I2C_FLAG_TRA) != RESET)In...
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 ...
