Having been emboldened by a successful conversion of my Thrustmaster F22 Flight Stick, I decided to try to capture all of the buttons on throttle too. A job that worked out easier than I expected as it turned out.
Having done some more research, it turns out that the chips in the handle are not MCUs, or at least not all MCUs. A few are shift registers, and, according to this post, talk SPI. The post also has a bit of code to capture the buttons.So, despite having the matrix all built, if I can just use a Teensy and build on that code, all the better.
A friend of mine bought me a Thrustmaster F22 for my birthday (thanks John!) a good number of years back, and I had many a fun sortie on DID's excellent EF2000 or F22 sims. It spent much of the last 10 or 12 years gathering dust rather than blowing away bogies, however, and due to the progression of technology, is no longer useful. Or at least this is what I thought, until I came across the controller modding community.
The DDS and related clock generation circuitry has made possible high accuracy, broad-banded programmable VFO functionality for very little money. Analogue Devices' AD9850 series offer HF frequencies for about €5. Higher frequencies can be had for not much more money, with the Silicon Labs SI570 with its near GHz maximum frequency offering the highest.
