I have bu The 24LC holds kilobits of data that is 32 kilobytes. The 24LS can also run on 3. The 24LS uses 3 pins for selection of its address, so you can use up to eight at once on the same bus. In reading and writing to the EEPROM one needs to realize that it has 32 kB actuall and one byte is not enough to address all the memory. If for example one wants to use address , that goes as follows: In binary, is Split that up into and , then convert the binary values back to numerical bytes to send with Wire.
That sounds more complicated than it is, as there are in fact two operands to do that. This will take the highest left part of the byte and drop off the lower end, leaving only the first 8 bits. This operand, when used with 0xFF will give the lower bits. Writing data to the 24LS Writing data is quite easy. First initialize the I2C bus with: Wire. The first data to send are the two bytes for the address were one wants to write to the memory.
First initialize the connection and provide the address of the data to read: Wire. The Power of the I2C bus is of course that various devices can be connected to the same lines.
It is key of course that they each have their own address. A print design can be found here Approx.

Dagami So for example you keep A0: It connects the SOT package pins to the same signal position of the 8 pin DIPmechanical and electrical connections are supported by this adapter. I will try in about an hour. Atmfl up or log in Sign up using Google. Can you give more information?
