Hi,

I am working on the X series PCIe-6351 encoder input by using an example gpctex4.cpp from X series DDK. It seems counting fine. However, it doesn't reset the counter even it is setup as follow:

counter->Gi_Mode_Register.setGi_Loading_On_Gate(nC​ounter::kReloadOnStopGate, &status);

counter->Gi_Mode_Register.setGi_Trigger_Mode_For_E​dge_Gate(nCounter::kGateLoads, &status);

and

counter->Gi_Counting_Mode_Register.setGi_Index_Mod​e(indexMode, &status);  //indexMode = nCounter::kIndexModeSet;

Can anyone tell me what is wrong? Do I miss something?

Thanks,

Larry

Hello,

What are you doing to reset the counter after you make these changes to the example?  For instance are you connecting a 5V signal to the Z input (PFI2)?

With your changes, connecting 5V to the Z input results in the encoder seeing a 0 degree rotation change....which is a reset.

Thanks,

Steven T.

Just closing the loop in case others search and find this post later. Larry shared his resolution in another thread:
