Other Parts Discussed in Thread: TDC7200EVM, TDC7200, TDC1000
I'm working to develop a product that will sense the level of fluids in a tank up to approximately 72 inches in heights. I have just purchased a TDC1000 TDC7200EVM. I have the GUI up and running and it appears to be connecting and controlling the EVM well. However, i don't seem to be able discern a difference in distances at all. TOF seems to always display a figure around 32000ns with a SD of 0.2ns. I have attempted to sense through air and water, without success down to just several inches. Is there a suggested setup for the TDC1000 or the TDC7200 that will result in allowing me to read distances? I am seeing both start and stop pulses, however the differences are fixed as I move target away fro the transducer. The composite waveforms also look fixed at approx 32000ns from each other. Can someone give me a little guidance here. Is the TDC1000 TDC7200EVM an appropriate chip set to handle my 72" project?
Thanks
