Link of the available pins and peripherals outdated (B-L072Z-LRWAN1)

I'm trying to get some kind of access to the GPIO on my B-L072Z-LRWAN1 but i've been stuck so far...

I've tried to set up the GPIO but i'm unable to get any kind of access to any of the pins.. I'm only able to transmit hardcoded values which pains me a lot.

I was hoping to find some useful information with a more detailed pinout map but the links are broken, does anyone have any kind of idea or the link to the actual map?

Thanks a lot!

Hi Maxime

Pin overview is available in the platform MBED page : https://os.mbed.com/platforms/ST-Discovery-LRWAN1/

Can you explicit the uncorrect pins ?

Can you copy/paste some code part ?

Jerome

Hi Jerome

I know this page, i was posting my question from there, but i was pointing out that the links to "PeripheralPins.c" and "PinNames.h" was broken.

Back then i was un-sure I was using the correct code to initialize the correct pins, so I hoped to find the right pin cast in these documents, however i was able to fix that at the start of the week, just forgot to close this issue!

Thank you for the reply though, it appears the main problem is that I was a bit dumb when I initialised the GPIO in my code... I can now use pins to get some voltage level via the ADC!

Sorry to have taken up some of your time,

Have a nice day,

Maxime

Hi Maxime,

I found the following user manual on ST's website, it looks like page 18 has a detailed list of the pin names and their functions: http://www.st.com/resource/en/user_manual/dm00329995.pdf

Please let me know if you have any questions!

Hello!

I was able to fix it during the week, turns out I was just a bit in a rush at the end of the last week and I just got confused when initialising the GPIOs in my code...

I'll get back to you if I get stuck another time, thanks for the help!

Have a nice day,

Maxime
