Free evaluation board for 80C550 microcontroller
EV550WZ1 is a free evaluation board for 80C550 microcontroller, very similar to the
EV51WZ1. There are just a few differences:
- EV552WZ1 is dedicated for 80C550 in DIP40 enclosing.
Because the P1 port can not work as output, the memory
switching is controlled by P3.4 and P3.3 pins (instead of P1.5
and P1.4, like in EV51WZ1).
- Because of different memory switching it was necessary to change
the loader. The new loader is available as
source, and
compiled & mixed ready to write into an EPROM.
The PCB layout
is available in the Easytrax format.
There are also available printouts of
bottom layer and
top overlay in the PDF format.
License
The EV550WZ1 is a free hardware and accompanying software is also free (in the
GPL sense or in the "Artistic License" sense).
You may freely copy and modify our hardware and use it for any purpose, however
if you feel that your work is seriously based on the EV552WZ1, mention it in its
documentation.
