How do you control your cannon by the way? Using directional buttons or swiping the touchpad like a trackball?
Edit: You know you have a small area at the bottom to move around freely in all directions, don't you?

Well I kinda have that right now. I got 16 bytes pages and I got a register for selecting the page which allows me to have 8 bit addresses on a 4 bit machine. I can do basic math with the register when I rotate it into the accumulator.

Maybe factory leftovers? Unsold routers?

Hmm I really should pick up this project again. I'm kinda worried about the very limited address space. The address bus is only 8 bits wide so I can address 256 bytes of ram and programs can only be 256 chars long. Well this is my first cpu, so... good nuff. 4 bits cpu is not enough to run decent applications on so... it's used for control applications and or simple mathematical operations. The cpu will run trough 256 bytes in about 0.256 ms @2Mhz

I'm going to solder this up this weekend. I made it on a solderless breadboard first and it works just fine. If there are other people interested in this device: just let me know. I'll release the source code for the subroutines which drive this thing.

The data is probably signed.

Ok here's what I'm gonna do:
I'm load audio samples in audacity and I convert them as 8 bit raw. I copy the raw hex values and I paste them in sourcecoder. Then I copy the values divided by 16 to an appvar.
Will that work properly?  I guess there isn't a 4bit downsampling in Audacity...
Jimbauwen's converter still glitches, so: no it does not work properly

Custom sound device? I made a DAC for the TI84+, so I might be able to design one for the Nspire platform. The main problem is that I know very little about the Nspire and I don't have one, so some of you guys will have to do the coding and provide me with a signal which the control logic must interpret.

Heya, I built a digital to analog converter for my TI84+
I can write values to it easily using a subroutine I wrote. WA(nibble) writes a 4 bit value to the DAC
Now I need some 4 bit samples which I can use with it. Preferably compressed (two nibbles in a byte) and stored in an appvar.
Does anyone know how to accomplish this?
