I have a thermometer chip which communicates via 16 bit read/writes (3-wire). The first 8 bits are a write of the address while the second 8 bits are a read (or write depending on address, but usually will be read after configuration). The clock can be any speed I choose. I have a 6251 DAQ, 6541 hi-speed DIO analyzer, 6602 counter, RS-232, and RS-485 modules in a PXI chassis.
I'm not sure how to switch from write to read effectively (and in a timely enough fashion) to write the first 8 bits then read the last 8. The delay in switching from a write to a read is too long if I use the DAQ to write a waveform then read a waveform on a digital channel. Seems like the 6541 should be the beast for the job, but I'm not sure how to get it setup.
any ideas?
