How to use an STM32 to flash a bios chip with a bin or hex file?

My old PC motherboard's bios chips were corrupted and it's an old 1155 socket so there were no available replacements. I believe I have the necessary tools to attempt to erase and reprogram the chip, but I'm not sure what I need to do. There isn't mu...

Hi. I have a problem about STM32F105RCT7. I want to use CANBUS protocol in this IC. I sure I made the CANBUS configuration right. My problem is, I can transmit Txmessage even I can view my message on the oscilloscope.

 But I can not return my message by CANLINE. When I do the same operations in STM32F103C8T6, I can get answers from the Canbus line.I chose the stm32f105RC family to use double canbus. I can't solve the problem. Do you have any ideas?. Thank you.

How to reduce the I2C speed ?

I am working on a STM32F746G-DISCO with I2C got on Arduino style board.I would like to reduce the I2C speed because sometime this lock my app with some external DAC chip.At this time I am using:CAMERA_IO_Init();   BSP_TS_Init(480, 272);     and these...

[SOLVED] --- BSP_I2C_Read() hang my STM32 app ---

I am developping a touch screen user interface to control an audio preampl and dac.I have no problems with I2C bus to set the registers of CT7302PL and ES9018K2M but if I try to read a single register the application hang.This is my I2C configuration...

hi, community, when gpioC is configured as input mode and default pin state is low.i am checking all pin by connecting each pin to ground alternatively.in that I find that pc8 and pc9 do not go high.

currently i am using the stm32h743zi board.why pc8 and pc9 pins are not changed there transition state when they connected to 5v supply.
