3 years ago It turned out that fram.begin() does not return properly when using Arduino Due. For more info refer to this thread. In the example sketch changing
if (fram.begin()) { // you can stick the new i2c addr in here, e.g. begin(0x51);
Serial.println("Found I2C FRAM");
} else {
Serial.println("I2C FRAM not identified ... check your connections?\r\n");
Serial.println("Will continue in case this processor doesn't support repeated start\r\n");
while (1);
}to fram.begin(); should make the sketch working. Of course this is a workaround, no fix 😏
I'm trying to get some example sketch MB85RC256V.ino running on Arduino Due to interface with an Adafruit I2C FRAM breakout board. I've the issue that the IC is not detected at all. The I2C default address has not been changed and I'm using the official docs to setup the board.
With the Arduino Due (SDA/20 + SCL/21) I'm getting this output:
For comparison with the Arduino Mega (SDA/20 + SCL/21) I'm getting this output:
In all post comments in the Arduino forum I've found so far about people running the breakout board and the Arduino Due successfully report that they are using own libs. Can someone confirm that the official libs support the Arduino Due and Adafruit I2C FRAM Breakout Board?
