[ESP8266] Chip Information 읽기

원래는 Chip ID 만 알려고 했다가,

구글링을 해 보니, 더 많은 정보를 얻을 수 있었습니다.

다음 사이트에서 참고했습니다.

그냥 스케치 프로그램만 건드리면 되네요.

소스 코드는 다음과 같습니다.

void setup() {
  char ser_tx_buff[100];
  
  Serial.begin(115200);
 
  Serial.println();
//ESP.getFreeHeap();// returns the free heap size.
//ESP.getChipId();// returns the ESP8266 chip ID as a 32-bit integer.
//Several APIs may be used to get flash chip info:
//ESP.getFlashChipId();// returns the flash chip ID as a 32-bit integer.
//ESP.getFlashChipSize();// returns the flash chip size, in bytes, as seen by the SDK (may be less than actual size).
//ESP.getFlashChipSpeed();// returns the flash chip frequency, in Hz.
//ESP.getCycleCount();// returns the cpu instruction cycle count since start as an unsigned 32-bit. This is useful for accurate timing of very short actions like bit banging.
  sprintf(ser_tx_buff,"1. getFreeHeap = %d\n\r",ESP.getFreeHeap());
  Serial.print(ser_tx_buff);
  sprintf(ser_tx_buff,"2. getChipId = %d\n\r",ESP.getChipId());
  Serial.print(ser_tx_buff);
  sprintf(ser_tx_buff,"3. getFlashChipId = %d\n\r",ESP.getFlashChipId());
  Serial.print(ser_tx_buff);
  sprintf(ser_tx_buff,"4. getFlashChipSize = %d\n\r",ESP.getFlashChipSize());
  Serial.print(ser_tx_buff);
  sprintf(ser_tx_buff,"5. getFlashChipSpeed = %d\n\r",ESP.getFlashChipSpeed());
  Serial.print(ser_tx_buff);
  sprintf(ser_tx_buff,"5. getCycleCount = %d\n\r",ESP.getCycleCount());
  Serial.print(ser_tx_buff);
  // put your setup code here, to run once:
}
 
void loop() {
  // put your main code here, to run repeatedly:
 
}
