Hi,
I'm trying to make an position measurment with a quadrature encoder.
My hardware is a6031E card, and I 'm using DAQmx 7.4.0.
I read the AN84. So I connected Channel A to Ctrl0_src (PFI8) and
Channel B to ctrl0_up-down (Port0.6). I used the
"quad_encoder_with_E-series_(STC)-daqmx.vi".
It first didn't work : il was counting up and not down or the opposite whether I was couting rising or falling edge.
Then it worked (I cannot see what I changed, I think I did not change anything but it's impossible).
And now, it doesn't work anymore. Even when I create a global channel
and test it in MAX, it counts up good, but when irotate the shaft the
other sense, it stays at his level and doesn't count down.
Can somebody telle me where I made a mistake and what I forgot.
Thanks.
