Writes data to the I2C device. C# Copy public abstract void Write (ReadOnlySpan<byte> buffer); Parameters buffer ReadOnlySpan<Byte> The buffer that contains the data to be written to the I2C device. The data should not include the I2C device address. Applies to ProductVersions .NET IoT...
现在,我们可以使用【i2c_smbus_write_byte_data】函数来向目标I2C设备写入数据。下面是写入数据到I2C设备的代码示例: ```c #include int reg = 0x00; int data = 0x55; // 写入数据到I2C设备 int write_data_to_device() { if (i2c_smbus_write_byte_data(file, reg, data) < 0) { perror("Fail...
