Programming STM32C011J6M6 with Arduino IDE

[GabrielGranzotto]

Hello,

I'm using an STM32C011J6M6 with the Arduino IDE to register with theST25DV64KC-IE6S3 's EEPROM.

I previously used the ATTiny85 and would like to replace it with the STM32C0 to maintain the entire solution with ST components.

I made some changes to the code but I can't register with the SDA/SCL of the STM32C0.

According to the datasheet, I should use pin 8 as SCL and pin 1 as SDA, but the registration with the EEPROM isn't working, I tested the eeprom address with ATTiny85 and it is 0x53

In the project with the ATTiny85, I didn't need to declare the terminal to perform this registration. Does anyone have a programming example that communicates via I2C?

#include <Wire.h>
#include <EEPROM.h>

#define EEPROM_ADDRESS 0x53
#define START_ADDRESS 0 

int currentAddress = START_ADDRESS;

int counter = 0;

void setup() {
  Wire.begin();
}

void loop() {
  writeToEEPROM(currentAddress, currentAddress);

  currentAddress++;

  counter = (counter > 499) ? 0 : counter + 1;

  currentAddress = (currentAddress >= 999) ? START_ADDRESS : currentAddress;

...

void writeToEEPROM(int address, uint8_t value) {
  Wire.beginTransmission(EEPROM_ADDRESS);
  Wire.write((address >> ‌‌8) & 0xFF); // High address byte
  Wire.write(address & 0xFF); // Low address byte
  Wire.write(value);
  Wire.endTransmission();
}
