LPC845 IAP flash

Hello,

hello, 
I'm writing about the LPC845 microcontroller. 
In particular I need to save data / variables in flash memory. I am using the provided iap_flash sdk as an example. 
The problem is that this example shows how to write and erase a memory sector. My question is: can I also read back this data?
thank you,
Luca

HI LucaCalicchia,

For example, you can use below code to read data from address 0x00003800:

volatile uint32_t get_value;

get_value = *(uint32_t *)0x00003800;

Hope this helps,

Jun Zhang

Hi Jun Zhang,

thanks for the information.

I thought there was a dedicated function, but even so it works very well.

Thank you.

Luca
