PIC PSP port bus contention
darkknight - 2005-11-21 02:45:00
Hi
We're trying to interface a PIC micro to an 8052 micro using the
Parallel Slave Port on the PIC. The 8052 can read bytes written to it
by the PIC ok, but when the 8052 writes to the PIC, the PIC tends to
read what it last wrote and not what the 8052 sent. The voltage levels

Neil Kurzman - 2004-08-05 02:46:00
rumor has it that it uses too many resources. C++ in an 8052 is probably
not the best idea.

I am interested in how a program could detect if it is running on an

device is not 8052 compatible, the test sihould not hang up the device.
One idea I have, is to write to the idata space and read back. But then
