PSoC 5, 3 & 1 MCU

Contributor

 I am using a PSoC 5 that includes two 32-tap FIR filters, an ADC_SAR, a 2-input MuxHw, Sync, LUT, DMA, PWM, Control Register, and an Opamp. My build gives two errors:

   

mpr.M0014:Resource limit: Maximum number of Opamp Fixed Blacks exceeded (max=0, needed=1).

   

mpr.M0014:Resource limit: Maximum number of DFB Fixed Blacks exceeded (max=0, needed=1).

   

What do these messages mean? I can't find any documentation on them.

   

Is my design too complex?

If you look at the datasheet part you have selected does

   

not have OpAmps or a DFB.

   

 

   

In workspace explorer, results tab, there is a file with suffic *.rpt, that

   

shows you resources and how many you have used and % used.

   

 

   

You can go to Project in main menu, pick device selector, and search

   

for a part that would meet your needs.

 Thank you so much, DanaakKnight.  I selected CY8C5868LTI-LP039 and the build succeeded.  I've struggled for two days on that and you solved my problem.  I did not realize that there was that much difference in the chips.

I have another post in to Cypress, eg, tool should not have allowed

   

you to place DFB, OpAmp, for the part you had selected, so hopefully

   

that will not happen again.

 @danaaknight, I upgraded to PSoC Creator  3.0 SP1 (3.0.0.3023) and your requested fix seems to be in there. If a component is not valid for a particular PSoc5 device, the component has a watermark "Incompatible" across it.  This lets you know that you either have to eliminate the component from your design or select another device that does support it.  Thanks again.
