Hi,

one can compare documentation level of open-source Numworks calculator with DM42 APIs:

How to say politely? Light years ahead ...

Hi,

I used the advice in this thread to build DMCP_SDK, SDK-Demo & DM42PGM successfully on Windows 10.

- I did not check the hash checksums.
- I did load the PGM files into the DM42 and all 3 worked!

It took me many hours of trying different ARM tools and diiferent MINGW downloads and some hours to figure out that only "mingw-get-setup.exe" V1.0 and only "gcc-arm-none-eabi-7-2017-q4-major-win32.exe" works. Without this combination, many different unrelated compile errors are coming and the target is not built.

Thank you so much for the advice in this thread which enabled me to set up a build system. It is not difficult (I am not a software dev), just heed the above advice, and the old version of gcc-arm tools - it does work.

Jaco

I got it
Ok good! Did you try the .pgm file in real DM42? In my case the hash check was failed

Good that it works now!

Maybe I will create a separate forum thread about environment settings for Windows.

P.S. I have switched from Lnux laptop to a new one, under Windows 10. And I stopped to use old command line tool - PowerShell works very well.
