Hi Ben,

1. Is there an official purchase of this airflow kit on the right side of the chip?

We do not provide the pipe and transducer for customer. 

Ben Qin said:

2. Does the gas not support single-frequency points, because the ADC data captured by single-frequency points has been very poor. Only sweep frequency is supported, which is the default configuration of Config_gas_200khz.

For gas meter, we recommend to use F1 to F2 sweep mode for excitation signal.

3. Config_gas_200khz with the default configuration, the actual test of this DTOF feels much worse

Customer may need to tune the configuration to get a better result. Please to this guide for how to tune the parameters. https://dev.ti.com/tirex/explore/node?node=A__AURAjHTDa0oVdd-2UTgIEQ__MSP430-ACADEMY__8HaEUeq__LATEST

Hi Cash,

Generally speaking, the range of sweep frequency is set between how much to how much? For example, 200kHz and 500kHz, how much is the appropriate interval to set.

Best Regards,

Ben
