This is the software for a microcontroller controlled DC
power supply with LCD display and RS232 interface.

The eagle schematic and board files for the hardware are included
in the hardware directory.

The power supply can be totally controlled via ascii commands over the 
rs232 serial line.  The following commands are available:
u=X set the voltage (e.g u=105 set voltage to 10.5V)
i=Xmax set the max current (e.g i=500 sets the current limit to 500mA)
s=1 or s=0 set to standby
u=? or i=? or s=? print the current settings 

Installation:
You need the GCC avr development environment if you want to build
the entire software. What you need is described in:
http://linuxfocus.org/English/March2002/article231.shtml

!!! Please read http://linuxfocus.org/English/November2002/article251.shtml
!!! for complete documentaion about the software/hardware

If you do not want to install the full environment then you can
use the pre-compiled avr code. You download it to the AVR uC with the
command:
make loadprebuild

To build and download the code use the command:
make load

In both cases you need an installation of the uisp programmer software.
Uisp needs the following kernel modules (2.4.x kernel):
modeprobe parport
modeprobe parport_pc
modeprobe ppdev
