ESP32C3 Hardware introduction

ESP32-C3 carrying RISC-V 32 position Single core processor , The clock frequency is as high as 160 MHz. have 22 Programmable GPIO Pin 、 built-in 400 KB SRAM, Integrate 2.4 GHz Wi-Fi And support long-distance Bluetooth 5 (LE), Support bluetooth Mesh (Bluetooth Mesh) Agreement and Lexin Wi-Fi Mesh.

• ESP32C3 Documentation
• https://www.espressif.com.cn/sites/default/files/documentation/esp32-c3_datasheet_cn.pdf
• Tested , adopt Arduino IDE Compile the uploaded code and print it externally spi flash Capacity , And by VSCode PIO Compile the uploaded code, and you can't find the relevant flash Capacity information .

The sample program

/* Blink This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/Blink */



void setup() {
    
  Serial.begin(115200);
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(12, OUTPUT);
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
    

  digitalWrite(12, HIGH);   // turn the LED on (HIGH is the voltage level)
  digitalWrite(13, LOW);   // turn the LED on (HIGH is the voltage level)
  delay(1000); // wait for a second

  digitalWrite(12, LOW);    // turn the LED off by making the voltage LOW
  digitalWrite(13, HIGH);
  delay(1000);

• be based on VSCode PIO Compile the same code

Program code compilation only takes 1.7% Conform to the configuration of user-defined partition table . But in VSCode PIO There is a problem with compiling the uploaded code , That is, the function cannot read the external SPI flash Capacity .

• be based on Arduino IDE Compiled serial port print information
  
• • be based on VSCode PIO Compile the uploaded code , Then the serial port prints information
