Other Parts Discussed in Thread: TDC1000
Hi,
I am trying to use the TDC1000-TDC7200EVM in a flow level sensing application. I have read the snaa220b, and have read through the register portion of the data sheet for both the TDC1000 and the TDC7200. I set the configuration registers. The register setting which i tried I am attaching here.
After doing the changes in the register setting I poured the water into the Vessel but I was not able to see any change in the TDC value. Every time with and without water it was sowing the constand value (~40 μs) .
Is there another configuration that will work?
I have tried RegisterFiles-TDC1000_RegFile_WaterFlow_1MHz_Audiowell_20141218 & RegisterFiles-TDC1000_RegFile_WaterFlow_1MHz_Shenzen_20141218 & RegisterFiles-TDC1000_RegFile_WaterFlow_1MHz_MorganCeramics_20141218. Nothing is working.
Please any help would be appreciated!
Regards,
Jyoti Sharma
