This is why i wrote the eepromex library, an extension of the standard arduino eeprom library. This includes bytes, longs, ints, floats and doubles. The arduino environment can be extended through the use of libraries, just like most programming platforms. For more info on these eeproms, check out the previous video. The arduino and genuino 101 boards have an emulated eeprom space of 1024 bytes. After you get it hooked up, connect the arduino to your computer running the arduino ide. The library comes with a number of short example sketches. Arduino library for arduino library for texas instruments tca9548a 8channel i2c switchmultiplexer.
Eeprom arduino library, nonvolatile data storage pjrc. Note that you read and write one byte at a time there is not an array read and write. Our experiments will be greatly simplified by using the arduino eeprom library, which is already included in the arduino ide. Libraries provide extra functionality for use in sketches, e. The eeprom library is included in your ide download. Read the eeprom and send its values to the computer. The microcontroller on the arduino and genuino avr based board has eeprom. However, the arduino standard eeprom library exposes only functionality for reading and writing a single byte, as described here. The eeprom library will automatically reduce the processors speed during the time eeprom data is written. This helps efficient usage of the limited eeprom memory. The eeprom library provides an easy to use interface to interact with the internal nonvolatile. You do this by adding an include directive to the top of your sketch. In this video, well use an arduino nano to make programming eeproms e.
Arduino ascom focuser pro diy myfocuserpro is an ascom and moonlite compatible stepper motor telescope focus controller diy base. The eepromex library is an extension of the standard arduino eeprom library. The arduino microcontrollers have non volatile eeprom memory built in. The eeprom library allows you to read and write those bytes. The function returns an unsigned char containing the value read. This copy is slightly modified, for use with teensy. To add its functionality to your sketch youll need to reference the library header file. To use a library in a sketch, select it from sketch import library.
