A simple console for M5Cardputer + ESP32forth.

The current release is alpha.

The following components are roughly combined:

• ueforth
• M5Cardputer
• LovyanGFX
• FastLED

Build / flash the project with Platformio.

At startup, the console reads from the USBSerial input. Open PlatformIO : Serial Console and type on your computer. To use the M5Cardputer keyboard, type m5key-on.

The following words can be used to switch the console I/O : m5key-on m5key-off m5type-on m5type-off

To use the M5CardForth standalone, without serial, follow the steps:

1. Do either:

• Turn M5Cardputer power switch on, or,
• press and relase the button BtnRst (at the top-left of M5Cardputer).

2. Immediately after you complete Step 1, press BtnG0 (top-right).
3. After prompt ok is displayed, you may release BtnG0.

Both the M5Cardputer keyboard and console output will be enabled.

Supported keys:

• Alphanumeric and symbols
• Shift
• Enter and BS

The ctrl/opt/alt/fn/esc keys do not work.

forth/fastLed.fs

forth/lgfx.fs

forth/M5StampS3-gpio.fs

In addition to ESP32Forth standard words, several new words are defined to access the M5cardputer features. Currently under development, the specs will be changed in the future.

use /sd/myblk
s" /sd/myblk" open-blocks

You may copy forth/autoexec.fs to /spiffs/autoexec.fs (via an SD card), then the contents of the file will be automatically executed at startup. Type the following to run a demo.
