Description
I put this code in Arduino IDE. I have an Arduino Portenta H7.
/*
secureElement Random Number
This sketch uses the ECC508/ECC608 or SE050 to generate a random number
every second and print it to the Serial Monitor
Circuit:
- A board equipped with ECC508 or ECC608 or SE050 chip
This example code is in the public domain.
*/
#include <Arduino_SecureElement.h>
SecureElement secureElement;
void setup() {
Serial.begin(9600);
while (!Serial);
if (!secureElement.begin()) {
Serial.println("Failed to communicate with ECC508/ECC608!");
while (1);
}
if (!secureElement.locked()) {
Serial.println("The ECC508/ECC608 is not locked!");
}
}
void loop() {
Serial.print("Random number = ");
Serial.println(secureElement.random(65535));
delay(1000);
}It always generates 0 instead of random numbers.
I see the message printed in Serial Monitor:
The ECC508/ECC608 is not locked!
