Hey everyone.
I Have some ADC problems. I can get one ADC_delSig to work perfectly but when i add a nother one it gives me 3 errors.
mpr.M0014:resource limit:maximum number of DSM fixed blocks exceeded (max=1, needed=2)
mpr.M0014:resource limit:maximum number of decimator fixed blocks exceeded (max=1, needed=2)
cdf M0005 CyDsFit aborted due to errors.
what i understand from these errors are, it can only run with one ADC. Can that be correct???
Regards Jason

If you need to measure two signals simultaneously using S/H - www.cypress.com/
and this using mux - www.cypress.com/

See this - www.cypress.com/
Normally you would use an analog mux to effect multople channels of
A/D conversion.
This might be useful - www.cypress.com/

Hello Dana.
Do you know if there are any project examples illustrating it?

If you right click a schematic component, pick "find example project",
for most components there is an example project that can be added
to existing project, or opened in a new workspace. But I am not
aware of example with a mux, which is pretty simple, just add it
and use APIs to switch channel, allow for settling time, and get A/D
result.

For some examples, see
- http://www.cypress.com/?docID=25372
- http://www.cypress.com/?id=4&rID=38576
- http://www.cypress.com/?docID=34834 (uses the SAR ADC tough)
- http://www.psocdeveloper.com/forums/viewtopic.php?f=42&t=9081
I think there is also an AppNote regarding using the multiplexer together with the DelSig ADC (which would include an example project), but I cannot find it right now.
