The mcp4822 module provides the MCP4822 class for non-blocking audio playback through the Microchip MCP4822 dual-channel 12-bit SPI DAC using PIO and DMA. It allows users to output audio by configuring clock, MOSI, and chip select pins with adjustable gain settings.
* Non-blocking playback for audiocore samples such as RawSamples or WaveFiles
* Support for sine wave generation via array manipulation
* Methods for controlling playback including play, stop, pause, and resume
* Monitoring of real-time playback status through the playing property

Using a sine to binary 16 bit number generator I programmed those numbers into a pair of 2716 eproms to get the 16 bit wide sine number 'lookup table' or in this case 'conversion table'. It works incredibly well and my sine/cosine generator drives a large X/Y C.R.T. P.P.I. (Plan Position Indicator 'think radar'). The display has 64K of pixels and the memory storage has the feature of OR'ing old data with new data that will leave a trail behind any moving object. Best wishes on your project.
