Webbus.write_byte_data(address, 0x40, value) Address of the device address, 0x40 is for function register to select DA, and value from 0-255 for the output voltage. The DA register like the AD registers are all 8-bit. Some of the Tkinter design was adopted from Programming The Raspberry Piby Monk, Simon. WebThe msgs[] themselves contain further pointers into data buffers. The function will write or read data to or from that buffers depending on whether the I2C_M_RD flag is set in a particular message or not. The slave address and whether to use ten bit address mode has to be set in each message, overriding the values set with the above ioctl’s.
