When it comes to AVR microcontrollers the most common programming option is In-System Programming (ISP). ISP interface is easy to use but in some scenarios it is totally unusable. The most common ...

The circuit was based on the use of Arduino AVR to build a high voltage programmer which can be used to fix pesky fuses. The circuit was based on the use of Arduino AVR to build a high voltage ...

The most common way of programming AVR microcontrollers is the In System Programming port. That little six-pin header with MOSIs and MISOs coming out of it will program every AVR you’ll ever come ...

If you want to use the reset pin as I/O, you will need to use High Voltage Parallel Programming to talk to your chip. Even if you don’t decide to do that, at some point you’re going to screw up and ...
