Use CONFIG_IS_ENABLED() macro, which provides more convenient way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs for both SPL and U-Boot proper. CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_...
插针上引出了 I2C1 和 I2C3,将设备连接到其上即可。 使用前需要先正确设置 PINMUX: # I2C1devmem 0x030010D0320x2# GPIOP 18 I2C1 SCLdevmem 0x030010DC320x2# GPIOP 21 I2C1 SDA# I2C3devmem 0x030010E0320x2# GPIOP 22 I2C3 SCLdevmem 0x030010E4320x2# GPIOP 23 I2C3 SDA Copy 然后可以使...

In STM32CubeMX, set I2C1 to "I2C" and USART1 to "asynchronous" Set up an external interrupt pin in GPIO settings, use "external interrupt mode with falling edge trigger detection" and "pull-up" settings. Activate the external interrupt in NVIC settings by checking the corresponding box. Co...
