Cannot compile for STM32F410Cx targets

[MCUdude]

There are a few STM32 targets I still would like to add to this project. One of them is the STM32F410Cx series.

I do have a working variants file for them. However, I'm not able to compile for either of them (STM32F410C8 or STM32F410CB). Here's the error I'm getting:

C:\Users\user\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.8.0\libraries\SrcWrapper\src\stm32\low_power.c: In function 'LowPower_EnableWakeUpPin':

This is the added boards.txt entry:

And attached you can find the variants file. once this is sorted out I can submit PR for this variant.

This is due to missing SYS_WKUPx definition in the PinNamesVar.h.
This file is generated thanks CubeMx XML description file anyway sometimes some WKUP pins are missing which leads to this issue as the one not found exists and defined to NC.
In that case, you have to check in the MCU datasheet which one is missing and define it manually.

Should be:

- SYS_WKUP2 = NC,
+ SYS_WKUP2 = PC_0,

Should be:

- SYS_WKUP3 = NC,
+ SYS_WKUP3 = PC_1,

Thanks, that did the trick! You can expect a PR soon 🙂
