Next time you call the I2C read routine, you give it an address, and again immediately say “have you got any data? Thus here it is: In the above setup, I knew it of course, as I myself wrote it.

In Maysome important research result was disclosed by Fairchild and Siemens. It was also used on video game cartridges to save game progress and configurations, before the usage of external and internal flash memories. I speak for myself, not Arduino.


Ee;rom to main content. Archived from the original on 3 May Electronic Inventions and Discoveries: The theoretical basis of these devices is Avalanche hot-carrier injection. Theoretical basis of the physical phenomenon itself is the same as today’s flash memory. I had to ask it twice And me not initializing the variable “result” is indeed not quite!

Serial EEPROM AT24C02

The data is transferred and received serially through serial data SDA pin. When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself.

Products such as real-time clocksdigital potentiometersdigital temperature sensorsamong others, may have small amounts of EEPROM to store calibration information or other data that needs to be available in the event of power loss. You give the I2C device an address, and then immediately say “have you got any data”? This last bit is 1 for write and 0 for read operation. Bi-directional pin for serial data transfer.

Archived copy as title Wikipedia articles with GND identifiers. I corrected my code, recompiled, uploaded, tried Eeprmo, there should perhaps be some time between available and receive Supply voltage; 5V up to 5. Siemens Forschungs und Entwicklungsberichte. I understand perfectly your point, AWOL.

It hasn’t yetso you return your unitialised variable “result”, but the library kindly buffers the data from the I2C bus when it does arrive. But each FLOTOX structure is in conjunction with another read-control transistor because the floating gate itself is just programming and erasing one data bit. The device can be addressed serially by the software.

During storage, the electrons injected into the floating gate may drift through the insulator, especially at increased temperature, and cause charge loss, reverting the cell into erased state.
