在 Arduino 程序中，digitalWrite(LEDpin, state) 是一个函数，用于将电平写入数字引脚。该函数有两个参数：- LEDpin：数字引脚的编号。- state：布尔值，表示要写入的电平。如果 state 为 HIGH，则表示将高电平写入引脚；如果 state 为 LOW，则表示将低电平写入引脚。因此，digitalWrite(LEDpin, state...
这是一个抽象函数，其作用是向指定的数字量接口写入数据。在这个例子中，要写入的数字量接口是LED对应的管脚，写入的数据是目标状态，亮或灭。
The Teensy has 21 digital I/O pins and the Teensy++ has 38, which you can use to control many types of devices or read information. You can access the pins by their number, or using their pre-defined names shown in the table. These names match the printing on the circuit board. Inpu...

Thesyntaxof a programming language is analogous to the grammar rules that define our sentence structure. Just as every sentence you write requires a punctuation mark (., ?, !), (almost) every line of code your write in Arduino must end with asemicolon(;). We'll see those soon, don't...

We could add it to the circuit, but we can also use the Arduino Uno built-in LED, which maps to the digital I/O pin #13. We can write a program in this way:#define BUTTON_PIN 3 void setup() { pinMode(BUTTON_PIN, INPUT_PULLUP); pinMode(13, OUTPUT); digitalWrite(13, LOW);...
I am working on a project, where I need to read a signal of a radio receiver that outputs a PPM or PWM using Simulink. I don't know if there is a Simulink block that does that? I tried servo read block thinking that it might read PPM but it didn't work. I managed to ...
