STM32WB Forth without BLE, USB, Filesystems, RTOS etc. is not complete, to build this by myself from the scratch overwhelms me. I would like to go the reverse way and use the STM tools like CubeIDE, HAL, CubeMX and integrate the Mecrips Forth into it. Forth as an interactive extension for the STM ecosystem. Mecrisp Forth running as a CMSIS-RTOS thread.

Added:

>

Already done

Integrated in Cube ecosystem
Forth as CMSIS-RTOS thread
Buffered console IO (20 KiB for UART Rx)

USB-CDC for serial communication. Redirect console IO like usb_emit, usb_key

Added:

Board Support Package BSP
- LEDs
- switches

Planned

Using RTOS from Forth
BSP
- Digital port pins D0 to D15
- Analog port pins A0 to A5
- PWM
- I2C

USB-MSC to make it possible to read and write blocks or include source files. INCLUDE vs BLOCK? Forth source files

Changed:

<
<

Command line editing like Gforth, buffered console IO.

>
>

Command line editing like Gforth
BLE 5.0

BLE vSP profile is proprietary, there is no standard serial communication profile. Redirect console IO like ble_emit, ble_key

Changed:

<
<

Calling HAL and other C functions
Calling forth words form C (prefix forth_ ?)
Event driven programming like LAIRD's smartBASIC, WAITEVENT ONEVENT.

BLE GATT (Characteristics, Services, Profiles)

Added:

Watchdog
Low power
Calling HAL and other C functions
Calling forth words form C (crawling through the dictionary)

Support for the floating point unit, CMSIS-DSP

Added:
