atmega fuse doctor - restores the locked fuse bits.

The ATmega fusebit doctor is a device designed to restore the factory configuration Fuse bits Atmel AVR family ATmega in the wrong cases record such. The most common mistakes or problems are a wrong configuration of clock source (fuse bit CKSEL), disable the serial programming interface SPI (fuse bits: SPIEN) or disable Reset output for the ability to use it as line input/output (fuse-bits ON). This simple and cheap device is intended for a few seconds to restore the configuration (to spice up the microcontroller). In the first case (wrong clock source) the problem can be solved, but in the second and third cases to spice up the microcontroller from the programmer to the serial interface impossible. Many people hesitate to collect parallel programmer, because it is more profitable to buy a new microcontroller. The device uses high-voltage parallel programming (HVPP), and the database contains the signatures of many of the microcontrollers of the ATmega. The user only needs to install the microcontroller with the wrong configuration of fuse bits in the socket and press the Start button. LEDs – status indicators are intended to inform the user about the progress of the recovery process. The illumination of the LEDs means: green led off – configuration Fuse bits restored. If set Lock-bits, then only checks the compliance of the current configuration bits to the factory settings, and if it matches, then it turns on the green led; included red led – error while reading the signatures of the microcontroller: can't read, there is no microcontroller in the socket or the signature does not match existing in the database device; green led flashes – the signature is correct, the configuration Fuse bits are not correct. Lock-bits are set, operation requires the erase of the Flash memory; red led flashes – the signature is correct, lock-bits are not set, but for some reason the Fuse-bits cannot be written. In firmware version 2.11 founded interactive exchange of ATmega Fuse Doctor by PC via COM port(RS232) or via USB TO UART BRIDGE on SR. Board divorced both options: a level Converter on MAH and USB TO UART BRIDGE on SR.
