JustInTime Project Pages

You'll find some descriptions of SX and PIC projects on these pages. And other stuf.

Projects

• As a 'hello world' #2 exercise, we've done some Knight Rider walking led experiments. These experiments demonstrate: pwm, either through SX Virtual Peripherals or inline and How to drive many leds with a few io-pins.
• 3D Miller controlled through rs-232
• Driving a shift register led display driver.
• Driving 4 seven segment led displays
• 'Very Limited Space' Midi Sustain Pedal.
• Fake Cricket.
• Reading Rotary Encoders
• A software project: An eclipse plugin for SX assembly language.

Programming

For newer PICs, the picprog programmer needs to be Modified. SX chips should best be programmed with the SX-Key or the SX-Blitz.

Although almost each project could be done with an SX as well as a specific PIC chip, the approach and philosophy between both is quite different. Look at the differences between the SX and the PIC we found (on the internet) and discovered (ourselves) between the two competitors.

A very useful utility for programming timing loops is PicLoops. It works for SX as well as PIC.

And how can you program a SOT23 package (i.e. the 10Fxxx series)? With a SOT23-to-DIL adapter.

Tutorial

As there are many, many tutorials about PICs on the internet, and the SX is very well documented by Parallax, we won't be serving another one here.

ToDo List

Here are some projects that need to be finished:

• Midi Chord generator
• 'Very Limited Space' Midi Sustain Pedal v2
• FireDept. Siren for the Firetruck of JustIn
• Traffic Light Toy
• Digital Analogue Clock with Traffic Light alarm
• Solarpower Chicken Lighting System
• PIC-based MidiFilePlayer
• Drumcomputer
• DCC Train control system
• Frequency Counter
• simple GPS based on rs232 receiver
• sunrise alarm clock

Reminder to the maintainers: more documentation is in the WikiDocumentation pages.
