TMS570LC4357: Variables values Storage

Dobby

Hi,

My system is controlled by an on/off switch. If a power failure occurs while the switch is ON, the system must not start automatically when power is restored .

For this reason, the system last state needs to be stored in non-volatile storage.

What is the recommended way to implement this?

Hi Dobby,

Refer below thread:

And also, you can find FEE examples here:

But there are many differant examples. Which one do i use ? Because my situation is a very easy.

I will store just one value in the storage.

Hi Dobby,

You can refer this example, this is a simple example to write into flash memory.

In this example i am writing array of data into the flash bank-7. Here first i am erasing the flash and then i am writing the data. You can use this example after programming you can assign a pointer to corresponding location and then you can read the data.
