您好,
TI提供了MSP430+TDC7201的参考设计 TIDA-060025 reference design | TI.com
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”。
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
MSP-EXP430F5529LP对应连接器定义请参考快速指南
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,
TIDA-060025中包括了TDC7201和激光驱动电路(2.2.3.1 Laser Driver and Laser Diode 和Figure 4-2),
MSP430提供LIDAR_START信号触发,与TIDA-060025评估板连接通过J7 J8。

但完整的MSP-EXP430F5529LP的接口定义在MSP-EXP430F5529LP Quick Start Guide (ti.com)中,存在空闲IO.
您好,
虽然两个板子用连接器连接,但TDC7201连接器只使用了部分MSP430的外接pin脚,
对于空着的引脚,可外接使用。
这边是给MSP430输入的嵌入式程序,想实现MSP430的P2.0接口输出PWM信号,但是在示波器上看不到正确的输出波形
#include <msp430.h> #define TASSEL_SMCLK #define MC_UP int main(void) { WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer //引脚P2.0配置为TA0.1(方向输出,功能引脚) P2DIR |= BIT0; P2SEL |= BIT0; //选择SMCLK,增计数模式,清除TAR TA0CTL=TASSEL_SMCLK+MC_UP+TACLR; //TA0CTL=TASSEL_2+MC_UP+TACLR; TA0CCR0=10000;//增计数模式下,该数值表示周期 TA0CCTL2=OUTMOD_6;//设置输出模式 //TA0CCTL1=OUTMODE_3 TA0CCR2=1000;//设置占空比 _EINT();//开启中断 while(1) { LPM0; } }
