MSPM0L1105: MSPM0L系列MCU使用IO口唤醒的疑问。

X HS — Wed, 06 May 2026 02:06:14 GMT

Part Number: MSPM0L1105

我看手册里描述是这样的，只有特定结构的IO可以使用唤醒功能让MCU退出低功耗模式，但是所有中断都可以触发唤醒控制器(WUC)，我想问下两种唤醒有什么区别吗？这是不是意味着所有能进行外部中断的IO口都可以通过中断来唤醒MCU？

MSP430FR6047: 程序死机问题

LT1 Shen1 — Tue, 28 Apr 2026 09:44:51 GMT

我参照DEMO程序，按照我的需求更改了一版软件程序，使用的是2MHz晶片，做了约50个部件运行均正常。现在我将晶片更换成了1MHz，并修改了程序，但程序会卡死在这个函数commonWaitForconversion，我确认硬件是正常的，因我烧录2MHz的程序连接2MHz的晶片时能够正常运行。以下是我变更为1MHz后的USS_userConfig.h:

这是我在同一个部件上，使用不同的激励脉冲个数采集到的AD波形，从这三个图来看，我认为最优的脉冲个数应该在12个或者13个，不知道我理解得对不对，我的判定方式是5个脉冲时后面跟着一个小整幅的尾巴，我最好的激励个数是在此尾巴前，我使用的晶片频率为2MHz。

当前我遇到一个问题，先描述一下我的测量环境，我的超声波探头使用的是2Mhz，为了保证USS_calibrateSignalGain函数的成功，我将USS_AGC_CONSTANT按照此前提问更改为了50。

问题描述：我保持流量不变的情况下，只更改液体（纯水）温度，我发现顺逆流飞行时间都能和与温度按照理论变化，温度升高声速加快，飞行时间减小。但我的DTof的均值居然也在变，1500ml/min的流量Dtof值在声程约4cm的情况下变化接近3000ps，这不符合理论情况。

Part Number: MSP430G2533
Other Parts Discussed in Thread: MSP430G2553

TI技术工程师：你好。

我在使用msp430g2553 单片机，现在要进行两道路的ADC转换：通道 0 （采集模拟信号），通道10（采集芯片内部的温度信号）。代码如下：

#include <msp430g2553.h>

unsigned int adc_ch0_val; // 存储通道0的值
unsigned int adc_ch10_val; // 存储通道10的值

void main(void) {
WDTCTL = WDTPW + WDTHOLD; // 关闭看门狗

// --- 1. 配置 ADC ---
ADC10CTL0 = SREF_1 + ADC10SHT_3 + REFON + ADC10ON;
// SREF_1: 使用内部1.5V参考电压
// ADC10SHT_3: 采样保持时间 64 cycles
// REFON: 开启参考电压
// ADC10ON: 开启 ADC

ADC10CTL1 = ADC10DIV_3; // 分频 /4 (暂时不设置通道，在循环里设置)

// 配置 P1.0 为模拟输入 (通道0)
ADC10AE0 |= BIT0+BIT1;

__delay_cycles(100000); // 等待参考电压稳定

while(1) {
// --- 第一步：读取通道 0 (P1.0) ---
ADC10CTL1 &= ~INCH_15; // 清除之前的通道选择
ADC10CTL1 |= INCH_0; // 选择通道 0

ADC10CTL0 |= ENC + ADC10SC; // 启动转换
while (!(ADC10IFG & ADC10CTL0)); // 等待转换完成
adc_ch0_val = ADC10MEM; // 读取数据


__delay_cycles(100000); // 等待参考电压稳定

// --- 第二步：读取通道 10 (内部温度传感器) ---
ADC10CTL1 &= ~INCH_15; // 清除之前的通道选择
ADC10CTL1 |= INCH_10; // 选择通道 10

ADC10CTL0 |= ENC + ADC10SC; // 启动转换
while (!(ADC10IFG & ADC10CTL0)); // 等待转换完成
adc_ch10_val = ADC10MEM; // 读取数据

// --- 数据处理 ---
// 这里可以添加代码将 adc_ch0_val 和 adc_ch10_val 发送出去

__delay_cycles(1000000); // 延时 1 秒
}
}

我是用查询的方式对两通道ADC进行转化。问题出在通道转换上面。

如果通道0在while（1）中前仿真结果一直是通道0 。即使执行了ADC10CTL1 |= INCH_10; 实践和仿真结果都是无法切换到通道0.如下图所示。请在百忙之中给予指导。不胜感激。

我自制了EVM430FR6043的电路板，之前买的电路板出现了烧录不进程序的问题，显示的好像就是找不到设备。现在我重新做了一个电路板，和EVM430FR6043大致相同，我通过了python GUI重新烧录了HID桥的5528芯片，烧录后指示灯亮了起来，且是正常情况下的亮灯。

EZFET的5528芯片我没有换，而是之前EVM430FR6043上的，我不确定这个芯片有没有坏，但是事实上的确还是出现了烧录不了程序的情况，我尝试重新给这个5528烧录固件，但是不知道通过什么方式才能烧录，UNIFLAH烧录的时候会显示no usb fet was found，且我的设备管理器的端口中没有出现这两个端口，我确定我已经下载了USB FET的驱动，但是仍然没有出现这两个端口。所以是否证明应该是我的5528芯片坏了呢？如果我重新买一个5528芯片该通过什么方式烧录固件呢，目前我只有一个MSP-FET430UIF烧录器。
