LPC1700系列串口中断接收程序，中断方式接收上位机数据并将接收的数据回送给上位机，借助串口调试软件，并设置波特率为9600，8位数据位，1位停止位，注意不要选中"HEX显示"。(LPC1700 series serial interrupt receiving program, to interrupt PC to receive data and receive data back to the host computer, with the serial debugging software, and set the baud rate to 9600, 8 data bits, 1 stop bit, be careful not to select the " HEX Show" .)

This is a simple bootloader for AT91SAM7 processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.(This is a simple bootloader for AT91SAM7{S,X}{64,128,256} processors.
