Hi,
I have a HTCL-2021 need to interface with my linear motion platform and DAQ device (NI PCI-6221). I need at least 16 bits output. Right now I only successful to generate 8 bit output (RESET pin set to high, SEL set to high). According to the datasheet, for proper operation of the inhibit logic during a two-byte read, OE and SEL must be synchronous with CLK due to the falling edge sampling of OE and SEL. The internal inhibit logic on the HCTL-2021 inhibits the transfer of data from the counter to the position data latch during the time that the latch outputs are being read. The inhibit logic allows the microprocessor / microcontroller to first read the high order 8 bits from the latch and then read the low order 8 bits from the latch.
The problem is I don't have microprocessor / microcontroller to connect with decoder IC. Instead the decoder IC need to interface with DAQ device (NI PCI-6221). I would like to ask if it is possible to use LabView to control the SEL and OE inputs from my DAQ device? If so, how to achieve it? Appreicate if anybody can help.
