In an earlier post, I shared some source code for a Teensy 2.0 that would use digital input pins to read an Atari 2600 joystick and output USB keyboard characters in iCade format. You may notice that this source code is vastly different than the simple “first thing I ever wrote on an Arduino” I just posted. The current source code incorporates debouncing, statistics, and is easily configurable from some defines and arrays.
Over the next few posts on this subject, I will share the two versions of source that connect my first trial to the current Teensy iCade source code. I have installed a code formatting plug in to this blog which should make the code display a bit nicer. I have even gone back and hand edited the previous posts to clean up the existing source, and fix some HTML nastiness that the software I am using wasn’t smart enough to prevent.
I should also note that, while I am new with Arduino, I am not new with programming embedded devices. I used to work for a company called Microware that made an embedded, multi-user, real-time operating system called OS-9. Before I began work there in 1995, I spent my youth programming 8-bit home computers like the Tandy/Radio Shack TRS-80 Color Computer. After all these years of feeling like technology has passed me by, I suddenly find myself back in a world where a tiny micro like the Arduino (or the TI MSP430s I program on at my day job) feels right at home.
Maybe one day I will learn how to program Android and iOS apps, but until then, there are still plenty of unused bits in these tiny computers to exploit.
More to come…
