That looks okay, but the menu screen scrolling looks a bit slow. Instead of moving the text a pixel at a time, try moving it by 2 or 4 pixels at a time. Other than that, the game looks pretty good!

My calc collection is still pretty small...

I really like the water physics! All the mechanics available (water, boulders, ...) should open up new posisibilities for level design. Does this use any 'undocumented' z80 features? I'd like to use this on my Nspire's 84 keypad.

Wow that is nice!!! :O Certainly beats MClite... I might have to ask you for help on block placing and crafting

Other / R-2R resistor ladder« on: May 31, 2013, 02:42:00 pm »
An R-2R resistor ladder is a nice little method of doing digital to analog conversion.
The one I made is 8-bit, so it can output 256 different voltages from 0V to 3.3V. Here are some pics: http://i.imgur.com/GPynZsR.jpg You can see on my oscilloscope that I'm generating a saw wave. All I'm doing is counting from 0 to 255 really fast over and over again, and putting the number onto the 8 pins of the PIC that are connected to the resistor ladder. You can also see on the oscilloscope that the wave isn't perfectly straight, and that's because of the resistors' tolerance that is differing the resistance slightly. There's nothing I can do to fix that, except use resistors with smaller tolerance. Here's a close up pic of the ladder: http://i.imgur.com/VObI1xr.jpg If you want to learn more about this take a look at the wikipedia page here. 190

Yeah, it would be major achievements and stuff from the year (or half-year) such as neat programs, Nspire hacking development, (cc40 programmers (me)), new OSes, maybe even some computer and Casio stuff.

AoC: It beeps, but I don't know if it's an actual speaker or just a beeper thing.
Keoni: I know. My electronics mentor and I have talked about using those ports, maybe even for something as simple as lighting up an LED. I'd have to find the pinouts though which I haven't yet. 192

Here are two programs I've made!
The first one is a simple counting program. You give it a number, it counts from 0 to the number and from that number to 0, then asks you if you want to run it again. Code: [Select] 90 INPUT "Count to: ";M This program is a stopwatch. Hold in the spacebar to count, release it to pause. Press X to clear the count. Code: [Select] 100 T=0:S$="STOP"

DJ, sorry no Illusiat, only one line display. And when I say no graphics, i mean no pretty pictures. There's still text!
Also i posted a picture of it on facebook (that's why it says Hello Facebook), here's the pic: http://i.imgur.com/u6z88sS.jpg 194

I just got a CC40 last night! It's a neat little portable computer made by Texas Instruments in 1983. It runs TI Extended BASIC (but no graphical commands) (TI BASIC is a version of Microsoft BASIC, i think), and I've already written some programs for it!
![]() It has a 2.5 MHz processor and 6k of static RAM. Pictures and possibly videos coming soon! 195
