This is library for storing data array in internal flash memory of MCU LPC1768. The flash data is empty every time we download program to MCU so it can be used in project where we don't have acces to file system like mbed development board uses.

Detailed Description
This is simple library for storing data to flash memory and reading it.
This allows us to have retain data without having to have external flash chip. This class uses NXP LPC1768 internal flash memory which give us 256B of flash size.

Example of use:
#include "mbed.h" #include "Flash.h" BusOut display(LED1, LED2, LED3, LED4); InterruptIn cntUp(p5); Timer debounceUp; Flash flash; char retainData[MEM_SIZE]; uint8_t counter; void countUp(void) { if (debounceUp.read_ms() > 500) { if (counter > 15) counter = 0; else counter++; retainData[0] = counter; flash.writeFlash(retainData); debounceUp.reset(); } } int main() { cntUp.rise(&countUp); debounceUp.start(); flash.readFlash(retainData); counter = retainData[0]; while(1) { display = counter; } }
