I am using PXI-6259 under Measurement studio VC++ and trying to generate 2 counter output synchronously.
 
********** DAQmx ***************
 
//set output channels
 (DAQmxCreateCOPulseChanFreq(CTR0_Task,"Dev3/ctr0:Dev3/ctr1","",DAQmx_Val_Hz,DAQmx_Val_Low,0.0,CTR_Freq,0.5);
My program is fine on single channel counter output nomatter CTR0 or CTR1. But it is not working on 2 channels setting. Is there any limitation on 2 channels counter output generation synchronously?
Please advise me thank you very much!
