Hi
i recently start a project on TIDM-ULTRASONIC board. i made one of these board and programmed it successfully but during the experiment somethings were strange for me.
according to my experiment on this board and TDC1000_7200EVM GUI, when you set some registers in GUI and you want to read it again to ensure that the registers are sets correctly by the GUI, the value of the read register may be varied with the values that i have set, after that if you press the read button once or twice it would read the register values correctly and as a result of those wrong values which is shown on read registers value the output and TOF AVG VALUE are wrong and it would be large numbers or negative and its confusing me!
another problem is: if every thing sets correctly and the Output of the graph seems normal,sometimes i see some abnormal spikes in the graph and i also attached the picture of the graph.
and the last thing i cant understand is about channel swapping. how the board change the channels? is there any PDF or documentation that described this subject in detail?
i'm using TIDM_ULTRASONIC_FLOW_METER and TDC1000-7200EVM GUI and also pair of 4Mhz transducer.
Thanks in advance.
