你好，我是用msp430fr5043做了一个气体流速的项目，目前直接使用的uss_lib中的demo做的测试，有两个疑问
1、始终无法确认totalTOF_UPS、totalTOF_DNS、deltaTOF、volumeFlowRate这个的单位是多少了。我们最终目的是需要测试速度，确认是多少m/s（米每秒）
code = USS_startLowPowerUltrasonicCapture(&gUssSWConfig);
checkCode(code, USS_message_code_no_error);
code = USS_runAlgorithms(&gUssSWConfig,&algResults);
checkCode(code, USS_message_code_valid_results);
#if (APPLICATION_ENABLE_CHANNEL_SWAP == true)
if(appSwapInterval == 0)
{
code = USS_swapCaptureChannels(&gUssSWConfig);
code = USS_swapAlgorithmsCaptureBuffers(&gUssSWConfig);
appSwapInterval = APPLICATION_CHANNEL_SWAP_INTERVAL;
}else{
appSwapInterval--;
}
#endif
#if APPLICATION_ENABLE_UART_DEBUG
/*
uartTxUSSResult(APPLICATION_UART_ABSTOF_UPS_DELIM,&algResults.totalTOF_UPS);
uartTxUSSResult(APPLICATION_UART_ABSTOF_DNS_DELIM,&algResults.totalTOF_DNS);
uartTxUSSResult(APPLICATION_UART_DTOF_DELIM,&algResults.deltaTOF);
uartTxUSSResult(APPLICATION_UART_VFR_DELIM,&algResults.volumeFlowRate);
*/
printf("\r\n%s:%f\r\n","UPS ",
code = USS_startLowPowerUltrasonicCapture(&gUssSWConfig);
checkCode(code, USS_message_code_no_error);
code = USS_runAlgorithms(&gUssSWConfig,&algResults);
checkCode(code, USS_message_code_valid_results);
#if (APPLICATION_ENABLE_CHANNEL_SWAP == true)
if(appSwapInterval == 0)
{
code = USS_swapCaptureChannels(&gUssSWConfig);
code = USS_swapAlgorithmsCaptureBuffers(&gUssSWConfig);
appSwapInterval = APPLICATION_CHANNEL_SWAP_INTERVAL;
}else{
appSwapInterval--;
}
#endif
#if APPLICATION_ENABLE_UART_DEBUG
/*
uartTxUSSResult(APPLICATION_UART_ABSTOF_UPS_DELIM,&algResults.totalTOF_UPS);
uartTxUSSResult(APPLICATION_UART_ABSTOF_DNS_DELIM,&algResults.totalTOF_DNS);
uartTxUSSResult(APPLICATION_UART_DTOF_DELIM,&algResults.deltaTOF);
uartTxUSSResult(APPLICATION_UART_VFR_DELIM,&algResults.volumeFlowRate);
*/
printf("\r\n%s:%f\r\n","UPS ",algResults.totalTOF_UPS);
printf("%s:%f\r\n", "DNS ",algResults.totalTOF_DNS);
printf("%s:%f\r\n", "deltaTOF",algResults.deltaTOF);
printf("%s:%f\r\n", "volume ",algResults.volumeFlowRate);
#endif
);
printf("%s:%f\r\n", "DNS ",algResults.totalTOF_DNS);
printf("%s:%f\r\n", "deltaTOF",algResults.deltaTOF);
printf("%s:%f\r\n", "volume ",algResults.volumeFlowRate);
#endif
2、正常放置，没有刻意给什么风，我的测试其结果如下：，不知道这个正常吗？目前都是使用的demo的默认参数，不知道怎么调整优化参数是测量更准确。
