M3m3M4n/esp8266-xvc-serial-bridge-control

ESP8266 based control unit, modded on EBAZ420X

Features

• Remotely hardware bootmode selection and reset
• Remote XVC and serial bridge:
  • ESP8266 XVC implementation from:
    • https://github.com/pftbest/xvc-esp8266.git

Pinouts

ALL PINOUT REFERENCES BASED ON NODEMCU ESP8266, ADAPT IF NEEDED

JTAG

• TMS = D2;
• TCK = D5;
• TDO = D6;
• TDI = D7;

Serial

• Board's serial connected to ESP8266 serial port 0

Misc

• D0 connect to MR pin of u65 through a 1k resistor, serve as board reset.
• D1 connect to R2584-U12-IO0 through a 1k resistor, serve as bootmode selector from ESP8266
• D4 has a 20k pullup, connected to a push switch (bootmode selector button) to GND

Default ports

• Command port: 42069
• Serial passthrough: 2222
• XVC: 2542

Notes

• Settings in arduino: 160Mhz, Vtable in heap || IRAM, V2 higher bandwidth
• Working unreliably in busy network, need to investigate, use hotspot or isolated network for now
