phungductung 0:8ede47d38d10 19 The I2C HAL driver can be used as follows:
phungductung 0:8ede47d38d10 20
phungductung 0:8ede47d38d10 21 (#) Declare a I2C_HandleTypeDef handle structure, for example:
phungductung 0:8ede47d38d10 22 I2C_HandleTypeDef hi2c;
phungductung 0:8ede47d38d10 23
phungductung 0:8ede47d38d10 24 (#)Initialize the I2C low level resources by implement the HAL_I2C_MspInit ()API:
