Hi, SDK12 does not have Pstorage. I want to show you how to add it.
Steps:
-
Copy the pstorage folder in SDK11 into the SDK12 \components folder.
-
Open any project in SDK12
-
Add pstorage.c in nRF_Libraries on the project side.
-
Keil, Options for Target -> C/C++ Tab inside
Okay.
its now code time:
-
Added library in to main.c
#include "pstorage.h"
-
Added Initalize Event functions
static void sys_evt_dispatch(uint32_t sys_evt){ pstorage_sys_event_handler(sys_evt);
}
-
Added Flash Read/Write Codes (handle,update and only read functions)
static uint8_t pstorage_wait_flag = 0;static pstorage_block_t pstorage_wait_handle = 0; static void flash_cb_handler(pstorage_handle_t * handle, uint8_t op_code, uint32_t result, uint8_t * p_data, uint32_t data_len) { if(handle->block_id == pstorage_wait_handle) { pstorage_wait_flag = 0; } //If we are waiting for this callback, clear the wait flag.
