PORTA.4 is not responding...

Hi,
I am using 18F452 at 20MHz for a project.

Why is that?
Any suggestions?

HPGL Code

Hi, what I am trying to do is read an HPGL file, and USART the X,Y coordinates. The code should omit all the data exept the line starting with PU and PD commands.

The module must accept 3 varialbles, - first (longword) is the number of pulses that will go on the step pin, and the ...

I supply -20V from another power supply. I see only initialization of the display, as it becomes black for a moment, and then goes white (green) again. That's all.

Hi Steven,

I got the message:

"Indetifier not declared: spiOscDev64"

when trying to compile your sample programs.

Why is that?

Thanks.
