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(F("Address = "));
Serial.println(_address);
Serial.print(F("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(F("Successful"));
}
else {
Serial.println(F("Failed"));
}
}
void loop() {
}
