VGA 8 bit dac (internal) #46

Closed Martin-Laclaustra closed 3 years ago

Martin-Laclaustra commented 4 years ago

This mode uses internal DAC to display 55 (or 256 if a voltage divider is used) levels of grey, or the same number of color tones of a particular hue depending on the combination of vga channels connected to the output pin. It works without any extra component. Resolves #45

This is implemented upon the master branch, not upon my modified interrupt-based driver like my other pull-requests. So this should be much easier to merge, as it is completely self-contained and it does not modify any file of the library (except ESP32Lib.h to add the driver).
