I2C怎么用

wx_8236422632

drv_i2c_write_series(I2C_SLAVE_ID, I2C_SLAVE_ADDR, I2C_SLAVE_ADDR_LEN, tx_data, 1);

        WaitMs(10);  // 等待测量完成

        drv_i2c_read_series(I2C_SLAVE_ID, I2C_SLAVE_ADDR, I2C_SLAVE_ADDR_LEN,data,6);
关于这两个函数 里面的各个参数是什么呢，特别是这个I2C_SLAVE_ID，它支持挂多少设备嘛？

As you know, you can have multiple devices on the I2C bus. So how would you identify the device that you want to read/write data to? That's why you need to define I2C_SLAVE_ID. You will find it in your device datasheet. The same with I2C_SLAVE_ADDR - what address are you going to write data to? Or read data from? You decide that - again looking in your device datasheet.
Hope that it helps.
