Installation

Installation to ESP

1. Download the MicroPython firmware from micropython.org dependent on ESP type

2. Flash firmware to ESP as described in the link above

3. Start a tool which supports download Python files to ESP like "uPyCraft" or "mpfshell" or "rshell" or "pycom"-plugin for VS-Code

4. Adapt the "telex.json" and "networks.json" file to fit your ESP pinout and TTY settings. See wiki page Configuration

5. Download all Python (*.py) and JSON (*.json) files from folder "/workSpace" to ESP.

6. Optional: Establish WLAN connection to use WebREPL and/or Telnet. E.g. use module WiFiManager

7. To use the USB connection to type and display ASCII characters import module "term" and start it with:

    import term
    term.run()
   

   This example code gets inputs from stdin (keyboard), convert it to Baudot-Murray-code and send it to software TTY. All inputs from software TTY are converted to ASCII and printed to stdout (screen).
