Porting from MFC to wxWidgets

This is a step-by-step guide for porting an application from MFC to wxWidgets based on my experience in porting Hippy.

Reference

• wxWidgets documentation for detailed class references.
• wxWidgets wiki for general wxWidgets programming guides
• Compiling using MS VC++

# This is Gray Code oscillator that can be used on Lattice ECP5 devices to measure time down to around 500ps of 
# precision (with no manual placement!) using only two (!) slices.
#
# In essence how this works is that we create a self-clocking counter that runs as fast as the FPGA fabric will
# allow. If we were to do this with a traditional counter, we would have to worry about propagation delay because
# multiple bits change at a time. If you use gray-codes, however, only one bit is changing at any given time so
# there are no issues with racing signals.
#
# If you drop this in a design and wire out the highest bit of the async_gray_count signal into a spectrum
# analyzer, you will see a dominant frequency of about 125Mhz. In other words, we cycle through all 16 gray codes

Removing a Mac's Firmware Password By Reflashing EFI ROM

According to Apple, the only way to remove an unknown firmware password from a MacBook (2011 and later) is to take it to the Apple Store with the original proof-of-purchase. However, I've found that there is another way, which I've been successful with for the unibody MacBook Pro--it's essentially just modifying a couple bytes in the EFI ROM, which should be simple. What's not simple, however, is figuring out how to read and write to the EFI chip. In this post, I'll talk about the process that I figured out and what worked for me.

The Official Method

Apple's method of resetting the firmware password is not reproducible, as Apple generates an SCBO file that unlocks the EFI using their private key. You can read more about this process here. The problem with this system is that, if you are in the unfortunate situation of neither having the firmware unlock pass
