Description: HIDKey
BootloadHID is a USB boot loader for AVR microcontrollers.-his is the README file for bootloadHID.
BootloadHID is a USB boot loader for AVR microcontrollers. It can be used on
all AVRs with at least 2 kB of boot loader section, e.g. the popular ATMega8.
The firmware is flashed into the upper 2 kB of the flash memory and takes
control immediately after reset. If a certain hardware condition is met
(this condition can be configured, e.g. a jumper), the boot loader waits for
data on the USB interface and loads it into the remaining part of the flash
memory. If the condition is not met, control is passed to the loaded firmware.
This boot loader is similar to Thomas Fischl s avrusbboot, except that it
is built on top of the HID device class. This implementation is more user
friendly on Windows, since no kernel level drivers need to be installed.

Description: This example shows how external devices such as external SRAM and FLASH, and
peripherals such as LCD-display, A/D, and D/A can be access with the
External Memory Interface.
To enable the External Memory Interface, the SRE bit must be set in the
MCUCR register and optionally one or more wait states.
When the AT90S8515 is operated in the external SRAM mode, port A is used as
a multiplexed low-order address bus and data bus while port C is is used as
high order address bus.
In this example data is written to external memory location $4000 and read
back and output to LED connected to port B.
Note:
When using AVR Studio 4 for simulation, External Memory Interface must be
enabled using the menu Option
"Debug -> AVR Simulator Options -> Device Selection and select check box

Description: The AVR is a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996. The AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to one-time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time.

Description: 用单片机，有些数据设置后需要掉电不丢失，一般首先想到的是使用eeprom，比如AVR中的Atmega系列有内部eeprom，也可以外接AT24C01之类的eeprom。这里介绍另外一种参数保存方法，Silicon Laboratories的C8051F系列，其内部程序存储区Flash可以在系统编程，功能类似于eeprom，掉电不丢失。
C8051F310内部有16K的在系统可编程Flash，地址从0x0000到0x3dff，以512字节作为一个扇区，这意味着每次擦除的时候，是对整个扇区擦除（置1），它不是面向单字节操作的，这点与eeprom不同。
-MCU, some of the data set is required after power failure, generally the first thought is to use the eeprom, such as AVR Atmega series of internal eeprom, you can add AT24C01 like eeprom. Here is another parameter preservation methods, Silicon Laboratories of C8051F series, its internal Flash program memory can be programmed in-system, similar in function eeprom, power failure. C8051F310 internal 16K in-system programmable Flash, address from 0x0000 to 0x3dff, as a 512-byte sectors, which means that each erasure, it is for the entire sector erase (set to 1), it is not single byte-oriented operations, and this point and eeprom different.
