For our mechatronics projects we are mainly interested in the following pins: Power pins (3.3 V).; Ground pins (GND).; Analog pins (A0).; Digital pins (D0 - D8, SD2, SD3, RX and TX - GPIO XX); Most ESP8266 NodeMCU boards have one input voltage pin (Vin), three power pins (3.3v), four ground. stm32 的基础配置用 cubemx 很是方便. 猜你喜欢: 【stm32】点亮 led 【stm32】gpio 输入—按键检测 【stm32】0.96 寸 oled 显示屏(7 针 spi 协议)软件模拟 spi 【stm32】1.44 寸 tft 液晶屏显示字符、汉字和图片 【stm32】stm32f407 + ds18b20 碰出不一样的火

stm32具有1~3个adc。这些adc可以相互独立使用,也可以使用双重模式。stm32的adc是12位逐次逼近型的模拟 数字转换器。它有18个通道,可测量 GPIO(英语:General-purpose input/output),通用型之输入输出的简称,功能类似8051的P0—P3,其接脚可以供使用者由程控自由使用,PIN脚依现实考量可作为通用输入(GPI)或通用输出(GPO)或通用输入与输出(GPIO),如当clk generator, chip select等。既然一个引脚可以用于输入、输出或其他特殊功能,那么.
