I am using myriad-rf with LMS6002D chip, together with the zipper board and an altera FPGA.
I see there is a 12 bit databus, with a qsel signal to indicate if the data is Q or I. According to the ADC spec I see this data must be on 2’s-complement form.
I am trying to test this by sending two constant values (one for Q and another for I continuously), to see if I have set up the registers correctly. Should this type of simple setup work?
So far it does not seem to work. At least I am not able to measure anything on the X4 connector om myriad board.
What I am trying to do is to send sensor data collected by the FPGA. Can I send “raw” sensor data as I/Q signals or do I have to do some kind of encoding first?
