MSP430FR5043: MSP430 development for gas meter

Part Number: MSP430FR5043
Other Parts Discussed in Thread: OPA836, , MSP430FR6043

Hi experts,

Our customer is developing gas meter based on MSP430 EVM and meet the following issues

1. Based on the EVM430 development board, how to optimize the capacitor and resistor matching of the operational amplifier circuit for a 200K transducer and a 500K transducer?

2. For gas meters, which echo waveform is more conducive to software cross-correlation algorithm calculation? What is the recommended number of pulse excitations?

3. How to set the ADC acquisition window size in USS for echo waveforms?

4. How to configure the transducer frequency sweep operation in USS to dynamically find a suitable center frequency?
