Lincoln DAC Example
From Manuals
Digital to Analog Converter (DAC)
Compatibility Lincoln 60, Lincoln 60E
The NXP LPC1769 microcontroller used in the Lincoln controller line supports one channel of 10-bit DAC that has an update rate of 1 MHz. The DAC signal is available on pin 7 on the following header:
Lincoln: Analog to Digital connector pin out
This example shows how to use the DAC to generate triangle and square waves. The signal output is shown below. In integer format the 10-bit outputs go between 0 and 1023 (0x03FF) for the range 0.00V to 3.30V in steps of 3.22 mV. Op-amps or other alternatives should be used to implement scaling and isolation.
