Store data in flash

[srv 2]

Can anyone please help me how can i store a data/value in MC flash memory during prgram execution and use that value always (means after reset the launchpad)?????

i want to store ADC value in my launchpad memory and use that value algin after several reset.

Please specify the MCU you're using, so it makes easier to those who would help you to answer the question, as each MCU has its dedicated EEPROM management.

 

Of course, EEPROM management is included as a library in Energia.

• For MSP430: see https://github.com/energia/Energia/tree/master/hardware/msp430/libraries/MspFlash
• For Stellaris / Tiva C: see https://github.com/energia/Energia/tree/master/hardware/lm4f/libraries/EEPROM

Thank You.i am using msp430 launchpad.

Which one?

There are two: EXP430G2 and EXP430F5529LP.

 

Also, I believe the MspFlash library only works on the G2 variant.

That's correct. MspFlash only supports MSP430G2 series at the moment.

Hi

I use MSP 430G2553 Laughpad V1.5, Energia  version E0012. So when i use Flash_read_write is very difficult. Hard to save value to segment of MSP.

I have code in CCS, i test it and see it good.

And then i convert this code to energia, i see have some mistake.

I dont know what this.

I think is Watdog, but i cant replace this mictake. Please see and check it for me.

Thank

Code CCS

#include "msp430g2553.h"

#include "stdio.h"

#include "Library/UART.h"

#include "Library/Flash.h"

void main(void)

{

unsigned char Temp[5],TempD[5];

long gtri,temp,temp1;

char buff[50];

char i;

P1DIR|=BIT6;

WDTCTL = WDTPW | WDTHOLD; //Stop Watchdog

BCSCTL1 = CALBC1_1MHZ; //2 thanh ghi c

@@tranduythai there is an MSPFLASH library for the 2553: examples->MspFlash
