5 Examples

Two examples are provided with this application note. Both examples run on the EK-TM4C1294XL or EK-TM4C129EXL LaunchPad. They are similar but the first uses a polling method and the second uses interrupts.

There is a third project that is included in the collateral. The project EE_RamBasedErase can be loaded into RAM and executed to erase the contents of the TM4C129x device EEPROM. This will make the device EEPROM mimick the state of a new device.
