It is also possible to write a program on the PC (Processing language or Python or C/C++ or whatever) that can transfer the file a "chunk" at a time over the USB/Serial port to the Arduino board so that the Uno doesn't need the SD card interface to do the deed. And of course you need for your Arduino software to read bytes or lines from the data file to be able to send them to the EEPROM. I have used Adafruit Data Logger Shield, the Wave Shield, and various of my own designs that are topologically similar to them. If you are going to store the file (binary or Intel Hex, or, perhaps Motorola S-Record) on SD, you will (obviously) need an SD card interface to the Arduino. You will need a couple of resistors a capacitor and some jumpers to connect power, ground and a couple of data signals from the Arduino Uno to the solderless breadboard. You don't need a separate processor on the solderless breadboard. If they re not in DIPs, you will have to work out some kind of transition board that takes a SOIC socket (or whatever package you want to accommodate).
They can still be programmed from an Arduino UNO with a slight modification of the Wire library and no additional components.)Īre the EEPROMS in a DIP-8 package? If they are DIPs, you can plug them directly on your solderless breadboard (or you can get a socket if it makes you feel better). What kind of EEPROM? The I2C serial ones like 24C04, 24C256, or what? Do you want to program small ones (up to 24C16) or larger ones (24C32 or larger)? The programming sequence is slightly different.Īre the EEPROMS capable of operating from +5 Volts? (There are low-voltage versions of some of them that won't tolerate +5 Volts. Would it be po(s)sible to somehow attach a chip to the bread board with a socket or something and get it to program a certain file to that?īefore I burn a bunch of bandwidth giving information that you might not need, maybe you can give us a few details on what, exactly you have in mind. OK-Now we're talking: A proposal for a marriage of Problem and Solution! So I want to try making my own eeprom programmer with it. I have had my arduino uno for a while and hav(e)n't found a project for it yet
