- Fri Jan 30, 2015 1:08 pm #8528 UPDATE: We are consolidating the code into a single driver as it is expanding quickly ... the new code set is locate here:
https://github.com/sfranzyshen/esp8266_tpm2net

This is a custom firmware for the esp8266 wifi module that will drive a strand of ws2812 LEDs using the TPM2NET protocol. I was successful at driving 132 LEDs (11x12 matrix) using this firmware and the pixelcontroller (v2.1.0-RC1) software. I expect it to operate more LEDs (hopefully up to 512 LEDs) ... This is based on work by Charles (cnlohr) and Frans (Frans-Willem)

there is also a rewrite of cnlohr's raw udp driver here ...

I'm really insterrested by testing your firmware but i'm a noob
I've falshed it, I've created a 15*16 neopixel led matrix (tested with arduino and work fine) for exemple with a wonderful software : Jinx! http://www.live-leds.de/
But can I have more explanation on running tpm2net ?
Like dat a are on GPIO 0 or 2, how can I set the module as AP or can it join my own network ?
I seeking for that kind of stuff since one year I create my matrix but without handy solution to manage it.
Thank in advance for you help.
Regards Stéphane
