器件型号：TDC1000-TDC7200EVM
大家好、
我正在尝试使用 TDC1000-TDC7200EVM 制作流量计、经过一个多月的实验后、我仍未获得任何结果。 我已经在论坛上阅读过有关此主题的内容、但尚未解决我的问题。 GUI 上的流程图为一个相当可靠的实验设置提供了混乱的值。 我有一根用螺钉固定在70度角的换能器上的钢管。 换能器的工作频率为1MHz、我知道声波会通过介质(现在为水)传输并返回到 EVM。
我已经了解到、稳定的实验设置至关重要、我认为该设置实际上应该提供一些合适的流量测量。
我正在附上一张实验装置的照片、供您发表意见。
此外、GUI 显示我需要修订版2、01、但无法找到更新固件的方法。
总之、我需要更新固件、工作设置文件、有关图形为什么会给出混乱的值而不是稳定的流图的指导以及实验设置的意见。
如果需要，可以提供任何帮助，并提供有关当前设置等的更多信息。
您好！
从 第24页开始的 EVM 用户指南( www.ti.com/.../sniu021a.pdf )介绍了固件升级过程。 如果无法使用 GUI 更新固件、则可以通过运行以下目录中的.exe 文件来自行运行更新过程：C：\Program Files (x86)\Texas Instruments\TDC1000_7200EVM\MSP430 USB Firmware Upgrade Example
我已附加一个配置文件、该文件设置为与音频单元测试管道配合使用、该测试管道具有1MHz 传感器、与流量方向直接相距72mm。 它还设置为与本应用手册 www.ti.com/.../snia020.pdf 中所述的阻抗匹配电路配合使用 。 您需要更改一些设置以匹配您自己的 setup.e2e.ti.com/.../6138.TDC1000_2D00_CONFIG_2D00_EXT_2D00_Sensor_2D00_Interface.txt
您能否从 GUI 中记录数据并将其上载到此处、以便我可以看到您获得的值是什么类型？
此致、
您好！
EVM 用户指南的链接对我来说不起作用、但我认为我找到了您要转至的文档、并成功更新了固件。
我已使用您建议的设置文件附加了一个包含来自测量的数据的文件。 我无法加载所有配置参数。 GUI 显示50个中有49个、但它不表示50个中的哪一个。
我需要为自己的设置更改哪些设置、哪些是静态的？ 我和我的团队一直在尝试了解设置"中断屏蔽"。 我在本文档中对此进行了阅读：
https://www.terraelectronica.ru/%2Fds%2Fpdf%2FT%2Ftdc7200.pdf
第13页的第§8.3.3.3节
但我不理解如何应用它或它的实际作用。 我将其解释为 START 脉冲和接收脉冲之间的时间窗口设置、在该设置中、我告诉 EVM 忽略该时间窗口之外的所有内容。

某些版本的 GUI 会生成不同数量的设置。 如果50个设置中出现49个错误、只需再次单击"Save config"并重新加载即可。 这将更新配置文件以包括正确的设置。
请尝试使用此链接、而不是 http://www.ti.com/lit/an/snia020/snia020.pdf 获取水流量应用手册、该手册将帮助您为应用选择正确的寄存器设置。
中断屏蔽选项将屏蔽 INTB 引脚的输出。 您可以选择哪些中断实际上将作为数字脉冲在 INTB 引脚上输出。 中断将始终显示在器件内的中断状态寄存器上。 它允许您控制微控制器在监控 INTB 引脚时将看到的中断。
可以每秒进行10次以上的测量。 该限制之所以存在、是因为 GUI 的 USB 通信速度很快。 在不依赖于与 GUI 通信的不同系统中、更新频率仅取决于您的时钟频率和实际飞行时间。
