Internal ROM

(2016.3.27 Created) 

　デバイス内部に設けられているROMへの読み書きを行うクラスです。こちらでダウロードできます。Arduinoの場合はEEPROM, STM32の場合はFlashが対象です。

The class provides reading and writing method to the device internal ROM. You can Download here. The ROM is EEPROM in case of arduino, and is Flash in case of STM32.

　Arduinoの場合は単純に読み書きするだけですが、STM32の場合は別ページを参照してください。

In case of arduino it can simply read / write, but in case of STM32, please refer another page.

Sample code

　Arduino用のサンプルコードです。STM32用はここにあります。

It is a sample code for arduino. STM32 code is here. 

#include "DKS_InterRom_Arduino.h"
DKS::InterRom *rom;

void setup() {
  Serial.begin(9600);
  rom = new DKS::InterRom();

  Serial.print(F("int value read/write test : "));
  const uint32_t u32w = 0x12345;
  rom->Write(0x00, u32w);
  uint32_t u32r;
  u32r = rom->ReadU32(0x00);
  if (u32w == u32r) Serial.println(F("OK"));
  else Serial.println(F("NG"));

  Serial.print(F("array read/write test : "));
  const uint8_t arrayW[] = {0x12, 0x34};
  rom->Write(5U, arrayW, sizeof(arrayW));
  uint8_t arrayR[sizeof(arrayW)];
  rom->Read(5, arrayR, sizeof(arrayR));
  if ((arrayR[0] == arrayW[0]) && (arrayR[1] == arrayW[1]))Serial.println(F("OK"));
  else Serial.println(F("NG"));
}

void loop() {
}
