A few more notes about 7-Segments display and IR receiver on Teensy

You may have noticed that I hooked up the Teensy board straight to the 7-segments display... That was probably not the best practice for a couple reasons: 1) It would probably be better to use the board to drive the display through transistors or a controller IC instead of using it to actually power it. 2) That's a lot of pins used. This was just an exercise to practice programming on Teensy.

Just as a reminder, here's a picture of it and it uses the NEC protocol.



And before I forget, here's the list of decoded IR commands from my remote.

Vol- FD00FF Play/Pause FD807F Vol+ FD40BF
Setup FD20DF Up FDA05F Stop/Mode FD609F
Left FD10EF Enter/Save FD906F Right FD50AF
0/10+ FD30CF Down FDB04F Back FD708F
1 FD08F7 2 FD8877 3   FD48B7
4 FD28D7 5 FDA857 6 FD6897
7 FD18E7 8 FD9867 9 FD58A7



Anyway, if I ever complete my Space Invaders in Teensy and Spartan project, I won't be using this display, I will most likely use the display on the Spartan board.
