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 HVProg project is a high voltage parallel programmer with the utilization of AVR microcontrollers for the purpose of disabling the RESET pin. The original STK500 from Atmel has been redesigned to ...

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 ...

AVR chips are convenient because you can program them in circuit at their operating voltage. That is, unless you screw up the fuse settings and they’ll no longer listen to an In System Programmer. If ...
