Description
using a normal I2C scanner code, i keep getting random addresses detected. i tried with another core (roger's core) with the same hardware and code and it works but when i switch to the stm32duino core it doesn't work anymore.
code:
`#include <Wire.h>
void setup() {
Serial1.begin(115200);
Wire.begin();
Serial1.println("\nI2C Scanner");
}
void loop() {
byte error, address;
int nDevices;
Serial1.println("Scanning...");
nDevices = 0;
for(address = 1; address < 127; address++) {
// The i2c_scanner uses the return value of
// the Write.endTransmisstion to see if
// a device did acknowledge to the address.
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0) {
Serial1.print("I2C device found at address 0x");
if (address < 16)
Serial1.print("0");
Serial1.println(address, HEX);
nDevices++;
}
else if (error == 4) {
Serial1.print("Unknown error at address 0x");
if (address < 16)
Serial1.print("0");
Serial1.println(address, HEX);
}
}
if (nDevices == 0)
Serial1.println("No I2C devices found");
else
Serial1.println("done");
delay(5000); // wait 5 seconds for next scan
}`
