Tedd OKANO / Mbed 2 deprecated IAP_internal_flash_write

Sample code for how to erase/write LPC1768, LPC11U24, LPC1114, LPC812 and LPC824 internal flash memory. This program uses IAP call of MCU's ROM routines. The IAP library also supports read/write of EEPROM in LPC11U24.

Dependencies:   mbed IAP

Sample code for how to erase/write LPC1768, LPC11U24, LPC1114, LPC812 and LPC824 internal flash memory. This program uses IAP call of MCU's ROM routines.

No filesystem interface available. This program is just an interface to flash erasing and writing. User need manage where to store the data in the flash area.

This IAP library supports read/write of EEPROM in LPC11U24.
