Hi,
I'm using a quadrature encoders with a PCI6025E board to measure an angle,
I want to use the COUNTER1 so I have connected line A of the encoder to PFI_3 and Line B of the encoder to LINE DIO7.
I have configure the 6025E with this code to read the counter 1 value :
status = GPCTR_Control(1, ND_COUNTER_1, ND_RESET);
status = GPCTR_Set_Application(1, ND_COUNTER_1, ND_SIMPLE_EVENT_CNT);
status = GPCTR_Change_Parameter(1, ND_COUNTER_1, ND_SOURCE, ND_PFI_3);
status = GPCTR_Change_Parameter(1, ND_COUNTER_1, ND_UP_DOWN,ND_HARDWARE);
status = GPCTR_Control(1, ND_COUNTER_1, ND_PROGRAM);
All the status code return by this functions are 0 and so OK.
But when I Get the counter value with GPCTR_Wathch().
When i tur
n the encoder in one way it count up well, but when i turn the encoder in the other way (down) I read a count that is is two times more than the count up (count down = 2 * count up) !!!!
Does someone have meet this problem before?
Any solution to solve this problem ?
Thanks.
