TDC7201: MSP430F5529L如何给TDC7201提供参考信号？

您好，

        TI提供了MSP430+TDC7201的参考设计 TIDA-060025 reference design | TI.com

您好，我查看了您说的参考设计。但是依然不懂提供参考信号端应如何连接，按照说明书tdc7201的Figure51来说，如果使用TDC7201的两个TDC组合模式进行飞行时间测试，参考信号需要一端连接NSP430，另一端连接TDC7201。目前我知道我需要两个SMA端口分别连接TDC7201的START1和START2端以输出参考信号，而参考信号输入端应选MSP430的哪个接口？

您好，

    TDC7201就是TOF传感器，MSP430只需回读转换后的结果即可。  两个TDC组合，是说并联吗？

    请看用户手册“Figure 2-6”。

是的，我想采用TDC1和TDC2组合模式进行飞行时间测量，因为我参考了您说的Figure 2-6，查看到msp430如果给tdc7201提供参考信号，msp430需要连接tdc7201的START1和START2两个端口，目前的问题是我不知道MSP430那一端需要连接哪个端口？

您好，

       硬件连接请参考TDC7201-ZAX-EVM User’s Guide (Rev. A) (ti.com)       

 J1 J2定义请参考链接中用户手册18页原理图

您好，目前这边脉冲激光器为外触发方式，如何通过MSP430实现控制激光脉冲的发送，具体需要MSP430的哪个引脚连接到激光器触发口？

您好，

    任何GPIO都可以，如果您用的是TI的评估板，就参考前面回复。

Output Interface: On the MSP430F5529L, you can use the GPIO (General Purpose Input Output) interface to output a reference signal. Specifically, you can select a pin configured for output mode, such as P1.0 or P2.0.

Input Interface: The START and STOP pins of the TDC7201 are used to receive pulse signals. You need to connect the MSP430 output pin to the START pin of the TDC7201. the STOP pin can receive another signal depending on your application requirements.

Connecting Cables: Connect the output pins of the MSP430F5529L to the input pins of the TDC7201 using a suitable connecting cable. Ensure that the ports on both ends of the cable are matched, you can usually use DuPont wire or other suitable connectors.

Configuration Settings: In the code, ensure that the MSP430 pins are correctly configured as outputs and generate the required pulse signals for use by the TDC7201.

The TDC7201 is a Time-to-Digital Converter (TDC) chip manufactured by Texas Instruments. It is mainly used to measure the time difference between two input signals.BC547 transistor is a general-purpose NPN transistor produced by NXP. It is a Bipolar Junction Transistor (BJT) and is mainly used as an amplifier and switch. In short, the TDC7201 is a high-precision chip dedicated to the measurement of time differences, while the BC547 is a general-purpose transistor mainly used for amplification and switching circuits. The two have completely different functions and application areas.

您好，我现在有个问题，如果MSP430已经作为底板和TDC7201连接，那么MSP430的GPIO接口已经被TDC7201的接口占用，那如何通过MSP430的GPIO接口控制脉冲激光器发送激光脉冲（因为在我看来和TDC7201连接后已经没有多余的GPIO口）？
