Hi!

Just a few notes that may help improve the dumpster drive wirteup:

• The processor is a Cortex-M0 therefore it only has support for thumb instructions (that was not part of making the challenge difficult).
• The board I used (with small mods) can be found here https://github.com/bornhack/badge2017 on the master branch you'll find the bootloader and sample code (I used as base) and on the hardware branch you'll find the real cad designs I used.

As a side note the reason why this challenge is 100 points is because if you build the hardware yourself you only need to change the screen's I2C address for it to work.

I hope you enjoyed the challenge though :D

Hi ymgve:

how can you find out "../ is replaced before the path is accessed" ?

Thanks
