I2C EEPROM is external memory which can be added to a PICAXE system which keeps its contents even when power is removed.
I2C EEPROM and other I2C devices (DS1307 Real Time Clock) are connected to the PICAXE using a two-wire I2C bus and can be controlled with a range of I2C specific commands.
I2C EEPROM is available in a range of storage sizes.
This program demonstrates reading and writing to byte addressed eeprom
hi2csetup i2cmaster, %10100000, i2cslow, i2cbyte main: hi2cout 0, (b0) ; Write data to eeprom pause 20 ; Wait for write to complete hi2cin 0, (b1) ; Read data from eeprom debug ; Show result pause 1000 ; Wait a short while b0 = b0 + 1 ; Increment the data to write goto main ; And repeatCopy Code Submit an Example
This program demonstrates reading and writing to word addressed eeprom
hi2csetup i2cmaster, %10100000, i2cfast, i2cword main: hi2cout 0, (b0) ; Write data to eeprom pause 20 ; Wait for write to complete hi2cin 0, (b1) ; Read data from eeprom debug ; Show result pause 1000 ; Wait a short while b0 = b0 + 1 ; Increment the data to write goto main ; And repeatCopy Code Submit an Example
I2C EEPROM can be connected using two generic terminal block create modules to carry the SDA and SCL signals of the I2C bus.
