Having some fun with the MCL51 and an R-2R DAC.

We have two, eight-channel DACs made with a resistor ladder connected to the PMOD connectors of the Arty Xilinx Artix-7 test board.

The first picture uses the oscilloscope’s X-Y mode to display a 256×256 bit-mapped image.

The second and third images are made by sending the results of a lookup table to the PMOD connectors.
