isd4002 problems help required please

[BobK]

Hi Nick,

I haven't used a PIC in this manner but I think the line:
"TRISA = %00001111 'Bits 0-3 address select"
is wrong. TRISA sets the data direction for PortA.

Now if you had "TRISA = %00000000" then all of the lines of PortA are set as outputs. The next line should then be "PortA = %00001111".

This would then turn PortA 0 - 3 on and 4 - 7 off.

Sorry, I didn't look at the date of the original post!

Hi BobK,

PortA bits 0-3 are for a binary switch; they set the play address for the isd4002.

charudatt,
I have worked out all the problems myself, now it stores the address to eeprom and can be selected via the binary switch using a lookup table. Is this what you are after? Contact me via email in my personal info and I will send you the completed code.

Regards
Nick
