ch592 examples question

[s00500]

Hey, nice Project!!! I was able to build and upload some basic blink sketches to an ch592F

Now I know this might not be 100% related to this project... But I am trying to get this example moved over to pio...

https://github.com/openwch/ch592/tree/main/Application/PDF_DataLogger

but I cant make the libpdf.a link properly... I keep running into linker errors.. any tips ?

I tried adding buildflags pointing to the .a file without much luck...

Sorry for the late response. Can you post your current project with the platformio.ini? This hsould be as simple as

build_flags =
   -L<path where libxxxx.a is>
   -l<xxxxx>

This is what it looks like right now

[maxgerhardt]

That looks extraordinarily weird. Why is the whole Startup and StdPeriphDriver and RVMSIS lib lib/? When you set framework = noneos-sdk, the startup file, peripheral code, debug code and system code is already compiled for you, as sourced from https://github.com/Community-PIO-CH32V/framework-wch-noneos-sdk.

Let me just convert the original project properly to show you the clean way.

[maxgerhardt]

Example converted and added into https://github.com/Community-PIO-CH32V/platform-ch32v/tree/develop/examples/usb-pdf-logger-none-os-ch592.

Pay close attention to the platformio.ini and the two created library.json files. Pay attention to what files were added and which weren't. Cross-reference everything against the documentation, such as library.json and the LDF modes.

@maxgerhardt Exceptional!

Why was it done like I did it ? cause I did not know what I was doing ;-)

Thanks for including the example!

Falls es bei euch einen Link für die Kaffeekasse gibt wäre ich interessiert ;-)
