How to write a file in Tiva C TM4C123G

Hello Faisal,

The simplest method would be to use the FMA, FMD and FMC registers in the Internal Memory to write to a vacant are of the Flash.

HWREG(FLASH_FMA) = ADDRESS; // Program Address to write

HWREG(FLASH_FMD) = DATA; // Program Data to write

HWREG(FLASH_FMC) = FLASH_FMC_WRKEY|FLASH_FMC_WRITE); // Start write to flash

while((HWREG(FLASH_FCRIS) & FLASH_FCRIS_PRIS) != FLASH_FCRIS_PRIS); // Wait for operation to complete

HWREG(FLASH_FCRIS) = FLASH_FCRIS_PRIS; // clear the completion flag for the next iteration

Regards

Amit

Hi Faisal,

exactly you need wrote a logger with write into flash ,
tivaware example will be useful for you,

but you should also read something more about loggers

Hi Lukasz, do you you know good references (besides google) about loggers? Thanks

"Mousing over" Lukasz reveals his last presence here as, "Over one year ago." Beyond that - his post here was more than 3 years past - thus (his) response appears unlikely...

Would not your search/find/then review of (serious, commercial, data loggers) - followed by contact w/those firms - meet your (exploratory) needs?
