好像板子上面没有24C08,但是例程um0427FWLibexamplesI2CM24C08_EEPROM 中说: Hardware environment ==================== This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation boards with addition of the following hardware connection: - Connect I2C1 SCL pin (PB.06) to I2C EEPROM SCL (pin6) - Connect I2C1 SDA pin (PB.07) to I2C EEPROM SDA (pin5) - Check that a pull-up resistor (4.7K) is connected on one I2C SDA pin - Check that a pull-up resistor (4.7K) is connected on one I2C SCL pin - Connect I2C EEPROM Vcc (pin8) to Vdd - Connect I2C EEPROM Vss (pin4) to Vss
Note: The pull-up resitors are already implemented on the STM3210B-EVAL and STM3210E-EVAL evaluation boards.
