Hi, I'm trying to read and write a single byte to flash. I am using the following code:
#include <SerialFlash.h>
#include <SD.h>
#include <SPI.h>
unsigned char buf[1], sig[1];
unsigned long address;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
while (!Serial) ;
delay(100);
Serial.print("SerialFlash.begin ");
Serial.println (SerialFlash.begin(5));
address = 100;
sig[0] = 15;
digitalWrite (5,LOW);
}
void loop() {
sig[0]++;
digitalWrite (5,LOW);
SerialFlash.write(address, &sig[0], 1);
while (!SerialFlash.ready());
SerialFlash.read(address, &buf[0], 1);
Serial.print(sig[0]);
Serial.print(" ");
Serial.println(buf[0]);
delay(300);
}
on a mkr wifi 1010, and it doesn't work. I can write only once, and I also see some erratic behavior. Is it possible to write and read a single byte without using files? If so, what am I doing wrong?
Thanks!!
