As almost everybody, I have ordered a few esp8266 modules.
For me, the existing examples are not using enough ressources of the chip : it is a 80Mhz device, with lots of memory, so… why not trying to put some old code for the ZX81 emulator on the STM32F103, and try to have it run on the ESP ?
So here is :
Blinky on the ESP8266, but through a Z80 emulator running a ZX81 Basic ROM
Keyboard/Display is currently using an UDP connection to a small and ugly Python client on a PC (semi-graphics not implemented).
It is able to run ‘galaxian’ … 😉
Code is available on Github.
