- Wed Jan 31, 2018 9:06 am #73608 Yes, I have done it.

Uses DMA and 10% CPU without the need to yield()

Resolutions are NTSC 256x192, 320x200 and 512x224 B/W.
Double vertical resolution in interlaced mode.

Only 2 resistors and one pin needed for composite output.
Currently strugling with making it color.

Gonna make it into the ESP8266-TVout library.

Wont release it officialy until it's finished though.

They do not use the Code for Arduinos.
They use the I2S and DMA for output.
I had an old LCD with CVBS input, so I took an wemos D1 mini and the Apple 1 emulator Software, wih a ca. 7MHz low pass Filter between esp and Display.
