Array write functions

bool writeByteArray(uint32_t _addr, uint8_t *data_buffer, size_t bufferSize, bool errorCheck = true)

• Writes an array of bytes to the address specified.

bool writeCharArray(uint32_t _addr, char *data_buffer, size_t bufferSize, bool errorCheck = true)

• Writes an array of chars to the address specified.

Parameters Mandatory & Optional

uint32_t _addr

Address in memory where the data is to be written to. Mandatory

uint8_t *data_buffer

Pointer to data buffer to write the array from. Mandatory

size_t bufferSize

Size of the array to be written out to flash memory. Mandatory

bool errorCheck

Refer to Advanced use Optional

What they do

Write the array of values of the datatype and size specified by the user, to the address provided

Returns boolean

Returns TRUE if data written successfully, else returns FALSE

Example code:

#include <SPIMemory.h>

SPIFlash flash;

#define _bufferSize 8

uint8_t dataOut[_bufferSize] = {0,1,2,3,4,5,6,7};
// This data type should be changed depending on the type of data being written to the flash memory
uint32_t _address;

void setup() {
  flash.begin();
  _address = flash.getAddress(sizeof(dataIn));
  Serial.print("Address = ");
  Serial.println(_address);

  Serial.print("Data write: ");
  if (flash.writeByteArray(_address, dataOut, _bufferSize) {
  // This function should be changed depending on the type of data being written to the flash memory
    Serial.println ("Successful");
  }
  else {
    Serial.println("Failed");
  }

}
