Replace 'n' with the I2C interface number. ```bash i2cdetect -F n ``` -------------------------------- ### Flash STM32 via I2C with Modified Kernel Settings Source: https://github.com/p/stm32flash/code/blob/master/I2C.txt This command uses stm32flash to communicate with an STM32 device over I2C, assuming the I2C driver has been modified and permissions set correctly. The '-a 0x39' specifies the I2C address. ```bash #> stm32flash -a 0x39 /dev/i2c-7 ``` -------------------------------- ### Modify I2C Clock Stretching Timeout in Linux Kernel Source: https://github.com/p/stm32flash/code/blob/master/I2C.txt This snippet shows how to modify the I2C clock stretching timeout in the Linux kernel driver for a specific laptop's VGA port I2C controller. This is a workaround for bootloader v1.0 issues with long operations. ```c i2c->bit.timeout = usecs_to_jiffies(2200); /* from VESA */ + i2c->bit.timeout = msecs_to_jiffies(5000); /* 5s for STM32 */ ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
