monetaWriteArray()

void monetaWriteArray	(	uint16_t	address,
		uint8_t *	txBuffer,
		uint32_t	txNumBytes
	)

OPCODE: 0x02
Writes txNumBytes bytes of data starting at the address indicated by address.

Parameters

address	The 2 bytes address indicating the first location to be written to. Note page restrictions in manual.
txBuffer	Pointer to the tx bytes that will be stored in memory. Must have a minimum of txNumBytes elements.
txNumBytes	Number of bytes to be written to the device. txBuffer must have a minimum of this many elements.

Return values

void

Warning

Check datasheet for the maximum number of bytes that can be written, as well as the device behavior if writing goes beyond the page boundary.
