UserFlash.ino missing - HTCC-AB02A internal flash access needed

elbastos · August 18, 2021, 8:47pm

Hi,

Where is the UserFlash.ino example? The URL from Github is broken. By the way, I need to store some values in the internal flash of my HTCC-AB02A and need some examples to start with. Any hints.

Regards,

Hi,

I found it!

github.com

HelTecAutomation/CubeCell-Arduino/blob/master/libraries/Basics/examples/Flash/ASR650X/UserFlash/UserFlash.ino

#include "Arduino.h"

/*note that the chip has 1K user flash.;
* the size of user flash row is 256; 
* user flash row 0-2 can be edited;
* user flash row 3 is reservated, must not be edited;
*/

#define ROW 0
#define ROW_OFFSET 100

//CY_FLASH_SIZEOF_ROW is 256 , CY_SFLASH_USERBASE is 0x0ffff400
#define addr CY_SFLASH_USERBASE+CY_FLASH_SIZEOF_ROW*ROW + ROW_OFFSET

uint8_t data1[512];
uint8_t data2[512];
uint8_t data3;
uint8_t data4;
void setup() {
  // put your setup code here, to run once:
