okano 11:8dfc3217d1ca 2 * Sample of ISP operation for NXP MCUs
okano 11:8dfc3217d1ca 3 *
okano 14:a7b9f74fb856 4 * @author Tedd OKANO
okano 19:7a7381e78025 5 * @version 0.8
okano 18:b401da200216 6 * @date Sep-2013
okano 14:a7b9f74fb856 7 *
okano 14:a7b9f74fb856 8 * This program programs MCU flash memory through UART. It uses
okano 14:a7b9f74fb856 9 * "In-System Programming (ISP)" interface in target MCU (NXP LPC micro-
okano 14:a7b9f74fb856 10 * controllers).
okano 14:a7b9f74fb856 11 *
okano 14:a7b9f74fb856 12 * The ISP is done by PC and serial cable normally. The ISP protocol is
okano 14:a7b9f74fb856 13 * executed software on a PC. The software reads a data file and transfers
okano 14:a7b9f74fb856 14 * the data with the ISP protocol.
okano 14:a7b9f74fb856 15 * This program does same process of that. The mbed perform the function like
okano 14:a7b9f74fb856 16 * "FlashMagic" and "lpc21isp".
okano 14:a7b9f74fb856 17 * (This program not just copies the binary but also insert 4 byte checksum at
okano 14:a7b9f74fb856 18 * address 0x1C.)
okano 14:a7b9f74fb856 19 *
okano 14:a7b9f74fb856 20 * This program currently supports LPC1114(LPC1114FN28/102 - DIP28-ARM) and
okano 14:a7b9f74fb856 21 * LPC810(LPC810M021FN8 - DIP8-ARM).
