USB CNC updates

Updated schematic  and the testing program. I tested it and I will make a little movie about the test. I'm ready to make the "real" program.

Projects underway

Few project which I'm working on:

1. - Arduino Language layer for Jallib library - redefinition of pins matching Arduino board and same functions as in Arduino Language. All in one file, "freejalduino.jal". A separate file will be made for FreeJALduino MEGA board when this will be ready. Not all "Arduino language" functions will be available at first release.
        Status: Testing stage

2. - Windmill controller/logger - this project will use USB Serial library. Right now, I'm doing tests to see if I can keep USB connection alive while I'm counting pulses on a digital pin on a second period.
        Status: Design stage

3. - XYZ CNC Router motherboard/controller - well, here I'm thinking at two variants. One is to have all three steppers connected to FreeJALduino board connectors via MOSFETs (of course, everything made on a shield). And second,  having all three stepper controllers as separate modules, driven with opto-couplers  by FreeJALduino board. The host software will process gcode files and will send data to FreeJALduino board via USB Serial.
        Status: Testing the variant with steppers connected directly...

First tutorial on USB-Serial Jallib library

I started a little tutorial about USB Serial communications between the FreeJALduino board and PC. You have to press two buttons from keyboard to switch a LED on/off. You must use the Communication Terminal Tool from Jaledit.

You can find it here.

New FreeJALduino boards

Added new boards in FreeJALduino and FreeJALduinoMEGA pages.

Updates to jal package and Tutorials

Updated jal.zip archive from this page and changed the jal example from this page. This was necessary because of jallib svn changes in ADC library. The example is working again as expected.
