1. i2c write是一种单字节的数据传输方式,适用于需要传输单个字节数据的情况。 2. 在i2c write中,主设备向从设备发送一个位置区域字节,然后再发送一个数据字节。 3. 这种传输方式适用于一些简单的控制命令或设置参数等场景。 二、i2cblock write的特点 1. i2cblock write是一种多字节的数据传输方式,适用于需要...
i2c write和i2c block write I2C写操作分为两种:I2C写(I2C write)和I2C块写(I2C block write)。 I2C写操作通常用于向I2C设备写入单个字节或多个字节的数据。在I2C写操作中,主设备通过发送写入地址和寄存器地址来选择目标设备上的寄存器,然后发送要写入的数据字节。目标设备接收到数据后,会发送一个应答信号表示已...
Write data to an I2C slave device or an I2C slave device register. Using this block, you can also write data to a specific register on the I2C slave. For more information on I2C communication, refer to Support I2C Communication and Raspberry Pi I2C Interface. To open the pin map of the...

Hi, I need to use I2C to write and read data and I have seen official demo codes. I found that codes will block to wait transfer complete. Blocking type codes may waste mcu resource. So I want to write and read data per 5ms by no waiting and mcu handles other tasks. How can I...
