ISP_FuseRescue | ATmega88 High-voltage parallel fuse writer shield

ISP_FuseRescue is a C++ library typically used in Internet of Things (IoT), Arduino applications. ISP_FuseRescue has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The AVR mcu has the fuse byte but we do not see it at the arduino operation with the original state intact ordinarily. It to configure the operating state of the chip. If you are developing the AVR microcontroller in the native state with the ATMEL Studio, In rare cases it may inadvertently would rewrite the fuse bit. If its operation would rewrite the bits related to the reset vector for the clock source and the boot loader, the MCU cannot not be able to communicate with the outside by ISP or it is no longer able to be the ISP programming. At the Arduino IDE, it will take a error for the sketch writing such as below. This error will appear when the boot loader written into the ATmega328 chip of Arduino does not respond. There are various causes. Even if the fuse bytes of ATmega328 is not consistent with the circuit of Arduino and the chip itself does not start, it will occur such errors. When it happen, it will not be able to return the original state of the chip by the serial programming method because the chip itself is locked. it cannot be written the boot loader. But the chip can be used if undo the fuse bytes because it not been destroyed yet. In order to do this you need to write an 8-bit parallel the fuse bytes while applying a voltage of +12V. ATmega88/168/328 datasheet has described high-voltage parallel programming specification and the chip will be a good state by writing the correct value of the fuse in accordance with the procedure. To do this you must have some kind of circuit and software for writing the fuse. Tools for high voltage parallel programming of AVR microcontroller has been implemented by already various people, so it was published by SatE-o and Yuki's lab.. ATmega88 High-voltage parallel fuse writer for Arduino is the shield and sketch for the high-voltage parallel fuse write. Also, it has the following features as a high-voltage parallel fuse writer.
