Description: PSoC code sample: Precision Frequency Meter.
A high precision frequency meter. Using the hourly time signal broadcast over the public radio station, the local reference oscillator is accurately calibrated. The local frequency reference oscillator is contained in a temperature controlled housing. The meter also operates as a accurate clock synchronised to the national standard.
Development Environment:
This source code includes the PSoC design files as well as the source code.
It has been developed using PSoC designer (Version 4.1)
Port allocations:
p0.0 Ain Audio input (to PGA)

p0.2 Aout Vref (vcc/2) out
p0.3 Aout CompLow out
p0.4 Aout Amplified audio out
p0.5 Aout CompHigh out
p0.6 Dout Heater out
p0.7 Ain CompHigh & CompLow input (audio mode)- connect to p0.4
p1.0 Din Input to freq divider. Connect to CompHigh out (p0.5)
p1.1 Din Te
