After months of esp8266 experimentation, I “just” discovered this little chip has also a I2S Audio digital interface. To discover it you must install the Arduino IDE adapter and code directly in C++ (brr, ok not a breeze but not boring like Java :)

UPDATED and BUGFIXED!

MicroPython Repl command line is very nice, because you can telnet to the chip and read-and-evaluate python code. It is a great way of learning embedded IoT. The bad thing you cannot copy file while it is running, so experimenting get bad.

This is a VGA library for ESP8266. To use this library you need only 1 resistor and one DSUB15 connector. VGA signal generation based on https://github.com/hchunhui/esp-vga (thanks for your awesome works). [....]

The library implement a 512x480px framebuffer with 1bpp, where each pixel is stored as a single bit. The framebuffer is stored inside RAM and require 30720 bytes.
