dear sir
iam interfacing a TDC1000-TDC 7200 EVM board to the lpc 1769 controller for flow meter application .
iam facing one major problem.
which is
i got a responce from the sensor but the time of flight value is not varied based on flow rate it shows only 1 t0 15 nano seconds time of flight value even we are applying 120 to 140 nano seconds time flight value.
is there any wrong in my configuration please provide configuration values?
