基于新唐M0內核的智能空氣檢測儀程序設計

ID:277976 · 發表于 2019-8-10 17:04

NuMicro® NUC131系列特色為寬電壓工作范圍2.5V至5.5V, 工作溫度: -40℃至105℃, 內建22.1184MHz高精度晶振(1%準確度)。備有豐富的外設, 如CAN2.0A/B, 定時器, 看門狗定時器,多組UART, SPI, I2C, PWM, 12位ADC, 模擬比較器等.提供多種包裝 LQFP48, LQFP64。
1.lcd段碼屏顯示
2.傳感器部分：溫濕度 SHT31 PM2.5: 四方光電 PM2008 CO2 : CM1106 TVOC傳感器
3.4路觸摸按鍵：經典算法：長按短按持續按鍵復合按鍵
5，慶科wifi模塊串口通信
6.鋰電池充電升壓二合一
7.設備聯控：采用標準的MOSBUS RTU 協議

單片機源程序如下:
