Erase all from I2C FRAM?
I need to erase everything from my Adafruit I2C FRAM breakout board but I'm not entirely sure how to, and I can't seem to find anything that helps online at all. Does anyone have any pointers?

Re: Erase all from I2C FRAM?
You just need to cycle through the memory and reset each byte...
Code: Select all
#include <Wire.h>
#include "Adafruit_FRAM_I2C.h"
/* Example code for the Adafruit I2C FRAM breakout */
/* Connect SCL to analog 5
Connect SDA to analog 4
Connect VDD to 5.0V DC
Connect GROUND to common ground */
Adafruit_FRAM_I2C fram = Adafruit_FRAM_I2C();
uint16_t framAddr = 0;
void setup(void) {
Serial.begin(9600);
while (!Serial)
delay(100);
if (fram.begin()) { // you can stick the new i2c addr in here, e.g. begin(0x51);
Serial.println("Found I2C FRAM");
} else {
Serial.println("No I2C FRAM found ... check your connections\r\n");
while (1);
}
// Iterate through memory and reset each value...
for (uint16_t a = 0; a < 32768; a++) {
fram.write8(a, 0);
}
}
