Generate STM32 MCU pin configuration automatically on MCU

Building a project for STM32F4-Discovery I realized it's really hard to keep track of all the pins as they get configured in different files all over the project. It's either keeping a separate list of assignments and functions (maybe using STM's cube software) or just going through source files every time.

Or maybe just having MCU report how pins are configured?

Here's what I managed to get out of my STM32F407VGT6:
==============================
SMT32F407VG Configuration
------------------------------
PA0     Input           LOW,  NO_PULL
PA1     Input           LOW,  NO_PULL

STM32 tools: New MicroXplorer generates the STM32 pinout initialization code

While I'm still very angry with STM for what they've done to all the community efforts by breaking, again, all the links on their *new* website rendering all our howtos to useless texts, here's a piece of *presumably* great news: MicroXplorer now is able to generate code. I haven't tried it though yet, so be the first to give it a go and describe your experience.

Hacking Hakko FX-888 - with a common cathode LED

I've got Hakko FX-888 as my main working tool. Great tool, one thing is annoying though - you can't tell at a glance if it's on or off. I decided I'll hack it as Dave brilliantly suggested in this post: EEVblog #242 – Hakko FX-888 Soldering Iron Hack. However I didn't check before ordering and got myself a bunch of common cathode LEDs. Gosh, had to think myself :-)

OK, just in case you'll need I'll save you some minutes. Here's the schematics:

You'll also have to short the 2k2 resistor on PCB, or replace it with 0 Ohm jumper. Have a look at the video Dave posted for an idea on how to mount this within Hakko body (heat glue gun of course).

Happy soldering!

Cheers!
