I2C doesn't work on STM32WL55CCU6 variant #1467
Description
Hello, I'm working with the Generic Node board. This board implements an STM32WL55CCU6 and for that reason I'm trying to used the Arduino_STM32_Core #1459 where the variant has been modified to use Generic Node board with Arduino.
The prooblem comes when I'm trying to scan the integrated sensors on board by using I2C_scanner and it detect nothing, just put on serial port that there's an error on some address and finally no I2C devices detected. I check the variant an there's seems to be nothing worng on it about pin declaration, also I'm put in HIGH the LS1_SENSORS_EN so all the sensors on board can be ON.
About the I2C_scanner.ino here's a preview of the firmware
#include <Wire.h>
//TwoWire Wire2(PA10, PA9);
void setup() {
pinMode(24, OUTPUT);
Serial.begin(115200);
//I2C-1
Wire.setSDA(PA10);
Wire.setSCL(PA9);
//I2C-2
// Wire.setSDA(PA11);
//Wire.setSCL(PA12);
Wire.begin();
digitalWrite(24, HIGH);
Serial.println("\nI2C Scanner");
}
void loop() {
byte error, address;
int nDevices;
Serial.println("Scanning...");
nDevices = 0;
for(address = 1; address < 127; address++) {
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0) {
Serial.print("I2C device found at address 0x");
if (address < 16)
Serial.print("0");
Serial.println(address, HEX);
nDevices++;
}
else if (error == 4) {
Serial.print("Unknown error at address 0x");
if (address < 16)
Serial.print("0");
Serial.println(address, HEX);
}
}
if (nDevices == 0)
Serial.println("No I2C devices found");
else
Serial.println("done");
delay(10000);
}
