Actually I did exactly that and it returned nothing useful, but thanks for the links. I'll contact CCS directly...

Has anyone come across this or have any idea what might be causing it?

Not sure if this is the right place for this type of question, but I though I'd sound you guys out anyway...

I've just upgraded to CCS v4 and opened a known project and attempted to compile it. Str ...

Many thanks guys, good food for thought.

Hi all,

I'm designing a lock-in amplifier and I need to generate a TTL reference signal (no problem) but also a 90 deg phase-shifted version of that signal also. The Frequency of the signal will be ...

Sorry, but I've never used that chip.
I guess I would say try it and see.
Sorry that this wasn't much help.

Can anyone comment on this or any other Analog mux?

No problem!

The only probl ...

Thanks for the comments guys.

or if slow enough, a analog mux and the A2D that is on the chip.

I think I'll go down the analogue mux route and pick a really good 16-bit ADC (low noise). Switchin ...

Just wondered if anyone had come accross this ADC from Microchip and if it was any good (or had any issues with it!)?

I have an application where I am measuring 8 channels of DC voltage i.e. speed ...

Sorry, I didn't know what you needed as a result.
Since you need int8 then use the struct as shown in my code snip it.
2 chips can return a struct, or int16 and the int16 could be broken down into i ...

Thanks for your patience treitmey.

I'll leave the original driver as is and use the defines in my main.

With regards to the make16() function - surely I need to use make8()? Doesn't the 74165 dr ...

Thanks treitmey, I've got this far but I'm still not getting any data out of the first chip:

#include <16f877A.h>
#device ICD=TRUE
#fuses HS,NOLVP,NOWDT
#use delay (clock=20000000 ...

try %u instead of %d

Ahh, silly mistake! Thanks, that fixed the -128 problem :-)

Any ideas for multiple chips? I now have two chips daisy chained, but somehow I need to access the two bytes in t ...

This seems to be a bit more reliable, although I'm still getting -128 when the 8th switch is selected!!

#include <16f877A.h>
#device ICD=TRUE
#fuses HS,NOLVP,NOWDT
#use delay (clock=2 ...

I don't see where you increment i

Yes, there should be a for loop. Strange that it (almost) worked before though without it??!!

#include <16f877A.h>
#device ICD=TRUE
#fuses HS,NOLVP,NO ...

Ok, I've breadboarded a demo board to test this and its almost working. I've got an 8-way switch connected to the 8 inputs of a 74HCT165 with the wiper connected to +5V. The 8 inputs are pulled low vi ...
