GPIO 7 SCK

GPIO 8 為板子上的LED

GPIO 20 RX

GPIO 21 TX

測試程式
from machine import UART

uart1 = UART(1, baudrate=115200, tx=21, rx=20)

# 直接檢查 UART 是否收到數據

if uart1.any():

    data = uart1.read()

    print("收到數據:", data)

else:

    print("⚠️ 沒有收到數據，請檢查 mmWave 連接")

應用程式
# 2025/03/05-14:45
#mmWave 板子容易當機

import time

from machine import UART, Pin

# 設定 UART1 (ESP32)

uart1 = UART(1, 115200)

uart1.init(baudrate=115200, bits=8, parity=None, stop=1, tx=21, rx=20)

# 設定 LED (GPIO8)

led = Pin(8, Pin.OUT)  # 設定 GPIO8 為輸出模式 (控制 LED)

while True:

    if uart1.any():  # 檢查是否有數據

        data = uart1.read()

        if data:  # 確保 data 不是 None

            try:

                decoded_data = data.decode("utf-8")  # 轉換為字串

                lines = decoded_data.split("\r\n")  # 逐行分割

                for line in lines:

                    if line.strip():  # 避免空白行

                        print("模組回應:", line)

                        # 🔹 **檢查 ON 訊息，控制 LED**

                        if "ON" in line:

                            led.value(1)  # LED 亮起

                        else:

                            led.value(0)  # LED 熄滅

                        # 🔹 **解析 Range 數值 (單位 cm)**

                        if "Range" in line:

                            try:

                                distance = int(line.split()[1])  # 取得數字

                                distance_cm = distance #/ 10  # 假設數據是 mm，轉成 cm

                                print(f"📏 測得距離: {distance_cm} cm")

                            except ValueError:

                                print("⚠️ 解析距離數據失敗:", line)

            except Exception as e:  # **改用通用錯誤捕獲**

                print("❌ 解碼錯誤:", e)

    time.sleep(0.1)  # 降低 CPU 負擔
