28x1 Question

[tmack]

I received a 28x1 and project board for Christmas. Can I make the pins c0-c7 output pins? I have tried to mess around with the code and havent been able to figure it out. I have done a search and havent been able to find anything that makes sense to me. I am wondering if i can use pins a1-a3 as regular input pins as well. Thanks for any help.

a0-a3 can be used as inputs and c0-c7 can be used as outputs, look at the getting started manual, pages 74 & 75.

And also at page 22 of "Getting Started".

There are differences between the chips - e.g. 28X1 does not support infrain whereas the 28X does.

Thanks

Thanks Phil, I missed that.

brings me a question!
Is it possible to use the pulsout commant on port c and if so, what is the correct syntax?
i have a syntax error on this "pulsout pinsc 0,1"
Thanks for your replies

You have to use IRIN and IROUT for the X1's and X2's.

I'm not sure if you can use PULSOUT on PORTC, I dont think so but I could be wrong.

Port C can be used a simple output Eg High PortC 1 or Low PortC 2. There are other, dedicated output pin functions which vary from chip to chip Eg PWM and Serial Out.

Refer to manual 1, Appendices C (14M), D (08/08M), E(28X/28X1) & F(40X/40X1)
