Since Nano33 BLE does't have an EEPROM, I am trying to store a value to external EEPROM on DS3231. The code compile without error but after upload, the Com port dissapear and my pc doesn't recognize arduino board anymore. To get the board back I need to press reset button twice and upload a new sketch. Here is a code that I found on a Forum and should work: #include <RtcDS3231.h> #include <Wire.h> #define EEPROM_I2C_ADDRESS 0x57 byte sum = 123; int readVal = 0; void setup() { Serial.begin(9600); writeEEPROM(0, sum, EEPROM_I2C_ADDRESS); } void loop() { // put your main code here, to run repeatedly: readVal = readEEPROM(0, EEPROM_I2C_ADDRESS); Serial.println(readVal); delay(5000); } void writeEEPROM(int address, byte sum, int i2c_address){ // Begin transmission to I2C EEPROM Wire.beginTransmission(i2c_address); // Send memory address as two 8-bit bytes Wire.write((int)(address >> 8)); // MSB Wire.write((int)(address & 0xFF)); // LSB // Send data to be stored Wire.write(sum); // End the transmission Wire.endTransmission(); // Add 5ms delay for EEPROM delay(5); } byte readEEPROM(int address, int i2c_address){ // Define byte for received data byte rcvData = 0x00; // Begin transmission to I2C EEPROM Wire.beginTransmission(i2c_address); // Send memory address as two 8-bit bytes Wire.write((int)(address >> 8)); // MSB Wire.write((int)(address & 0xFF)); // LSB // End the transmission Wire.endTransmission(); // Request one byte of data at current memory address Wire.requestFrom(i2c_address, 1); // Read the data and assign to variable rcvData = Wire.read(); // Return the data as function output return rcvData; } Does anyone have any working example for Nano 33 BLE? cattledog July 21, 2021, 5:30pm 2 jureg: I am trying to store a value to external EEPROM on DS3231.

When I do that, your sketch stores and reads 123 in my testing. 1 Like jureg July 22, 2021, 12:00pm 3 Thank you cattledog. It works. I was searching a whole day for a library or code that would work on Nano 33 BLE and when the board stopped responding I just gave up. system Closed November 19, 2021, 12:01pm 4 This topic was automatically closed 120 days after the last reply.
