Running the demo

The log below shows the output of the dac normal demo in the terminal window:


DAC Normal Driver Example!

Output = 0.18V + (1.42V * input_code / 1023)

Please input the value(Ranges from 0 to  1023) to be converted.
1000
Please input the value(Ranges from 0 to  1023) to be converted.

Use the oscilloscope or universal meter to probe J4-4(GPIO_43), then the output voltage can be measured.
