---+ Mecrisp Forth for the !STM32WB

Interactive and extensible language. Built-in lexical analysis (tokenizer, parser), needs less than 32 !KiB Flash and 4 !KiB RAM.

The competitor is [[https://micropython.org/][MicroPython]], but it needs more than 250 !KiB of Flash.

But what about [[http://www.ulisp.com/][uLisp]]? It is also small and self-contained.

   * http://mecrisp.sourceforge.net/ Sourceforge, original project
   * https://github.com/jjonethal/mecrisp-stellaris GIT repository, fork with more supported MCUs and dev kits.

---++ CMSIS-SVD for !STM32WB

SVD 2 Forth
   * https://github.com/ralfdoering/cmsis-svd-fth
   * https://mecrisp-stellaris-folkdoc.sourceforge.io/register-generator.html#svd2forth

Install the [[https://www.st.com/en/development-tools/stm32cubeide.html][STM32CubeIDE]] and get the =STM32WBxx_CM4.svd= from the folder:
<pre>
Version 1.6: stm32cubeide_1.1.0/plugins/com.st.stm32cube.ide.mcu.productdb.debug_1.1.0.201910081157/resources/cmsis/STMicroelectronics_CMSIS_SVD
Version 1.7: stm32cubeide_1.2.0/plugins/com.st.stm32cube.ide.mcu.productdb.debug_1.2.0.201912201802/resources/cmsis/STMicroelectronics_CMSIS_SVD
</pre>

Install the Mecrisp-Stellaris and copy the =STM32WBxx_CM4.svd= into =common/svd2forth-v3=. Edit the =Makefile=
<pre>
common/svd2forth-v3> diff Makefile Makefile~
5c5
< FOLDED_SVD            = STM32WBxx_CM4.svd
---
> FOLDED_SVD            = STM32L07x.svd
</pre>

Edit the shell script =raw-svd-clean.sh=. Replace =gsed= with =sed=.

Generate the Forth and Assembler source files:
<pre>
common/svd2forth-v3> make everything
common/svd2forth-v3> make mem
</pre>

---++ Build

Linux packages:
   * cross-arm-binutils
   * cross-arm-none-gcc9
   * cross-arm-none-newlib-devel

   * stlink
   * stlink-gui
   * stm32flash
   * openocd

   * [[https://www.st.com/en/development-tools/stm32cubeprog.html][STM32CubeProg]]
   * [[https://www.st.com/en/development-tools/stm32cubemx.html][STM32CubeMX]]


---+++ !OpenOCD

!OpenOCD 0.10.0 does not support STM32WB, therefore I built the OpenOCD from the sources.
<pre>
$ git clone https://git.code.sf.net/p/openocd/code openocd-code 
</pre>

But openSUSE' jimtcl Package conflicts with the configure script, to prevent this:
<pre>
$ mv /usr/bin/jimsh /usr/bin/jimsh-unused
</pre>

The usual configure/make/install:
<pre>
$ ./configure
$ make
# make install
</pre>

/usr/local/share/openocd/scripts/target/stm32wbx.cfg

<pre>
/opt/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI -c port=SWD -ob displ
</pre>
