Development of esp-01s in Arduino (1)

parts ：esp-01s, ssd1306

development tool ：arduino

The deployment environment ： Please refer to online materials .

One 、 install arduino：

To https://www.arduino.cc/en/software download arduino

esp-01s The driver can be installed according to the actual situation . I didn't install , Use WINDOWS Self installed CH340 drive .

Two ： install 8266 library ：

open arduino after , stay file =》 Preferences Add additional board data as shown below ：

http://arduino.esp8266.com/stable/package_esp8266com_index.json

3、 ... and ： Click on Tools =》 Development board =》 Development management board , Screening 8266, Installation

 

  If ： Installation error , You can also use the following methods ：

Development documents of lighting technology ：

https://www.diandeng.tech/doc/getting-start-8266

  Four ：arduino Choose development board , Refer to the following for parameters

  5、 ... and ： Use ssd1306, Download library , I installed this . 

6、 ... and ： The equipment wiring is shown in the figure

7、 ... and ： The code is as follows ：

You can test esp-01s, Whether it can operate normally ： use blink Program

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, LOW);   
  delay(1000); 
  digitalWrite(LED_BUILTIN, HIGH); 
  delay(2000);
}

No problem , Connect ssd1306

#include <Wire.h>  
#include "SSD1306Wire.h"

const int I2C_DISPLAY_ADDRESS=0x3c;
#if defined(ESP8266)
const int SDA_PIN = 0;
const int SCL_PIN = 2;
#endif

SSD1306Wire display(I2C_DISPLAY_ADDRESS, SDA_PIN, SCL_PIN);

void setup(){
  display.init();
  display.flipScreenVertically();// Flip 
}

void loop(){  
  display.clear(); //  Clear the screen 
  display.setFont(ArialMT_Plain_24);
  display.setTextAlignment(TEXT_ALIGN_LEFT);
  display.drawString(10, 18, "wait");
  display.display();
}
