Using Arduino with an I2C EEPROM. I got my hands on an AT24C256 (256 kbit = 32 kbyte serial EEPROM). I found no library for it, so I created a small sketch with few functions to show how the i2c_eeprom_write_page and i2c_eeprom_read_byte functions work. Because this chip is I2C, it only uses the analog pins 4 & 5

void EepromInit(BYTE deviceAddr, BYTE speed, WORD maxEepromSize ), This function initializes the EEPROM on the I2C bus. Parameters: deviceAddr, i2c address of eeprom device (use EEPROM_ADDR_DEF to use EEPROM aboard the Flyport LITE). speed accepts only the following
Serial EEPROM READ speed is restricted more by the protocol than the process technology. The 2-wire I2C. (Inter-Integrated Circuit) products must add large inter- . diagram example. READ, WRITE, and ERASE. The attached 93LC66 timing diagrams illustrate the key concepts and timing parameters for each of these op-.
Here's an example sketch to write some data to the EEPROM. Walk through the comments in the code for an explanation about what's going on. Copy Code //Include the Wire I2C Library #include <Wire.h> /*This address is determined by the way your address pins are wired. In the diagram from earlier, we connected A0
They work with things like EEPROM's but not with microprocessor slaves that use clock stretching. The result is that erroneous data is read from the slave. Beware! Example Master Code This example shows how to implement a software I2C master, including clock stretching. It is written in C for the PIC processor, but should
Address of the I?C EEPROM (0xA0 in this example); Address of the memory location in the EEPROM; Data bytes (address will increase automatically). In this example we try to write the following bytes, starting from location 0x00, into the EEPROM: 0x12, 0x34, 0x56, 0x78, and 0x90. i2c_init_write(); // Sets the MAX2990 I2C
28 Jun 2013 So, the sequence to access to an specific address in the EEPROM array consist in: Generate the Start condition in the I2C bus (SDA low, then SCL low). Send the device address (0xA0 or 0xA1 if continuing with the example above); Send the high byte of the address to access; Send the low byte of the
6 Mar 2015 I2C EEPROMs are very popular in embedded system as they provides very good solution for storing data on a non-volatile storage device. AT24xxx series serial eeprom works on I2C protocol. This tutorial will help you understand in depth detail of i2c EEPROMs so you can easily use EEPROMs in your
Adding External I2C EEPROM to Arduino (24LC256). This tutorial was originally posted on the 10kohms.com website, which now seems to be no longer with us, so we have reproduced it here. In my last post I discussed using the built in EEPROM to store permanent data on the Arduino. All though this is a very easy and
