[[File:Avrisp.jpg|thumb|200px|SOIC 8 clip attached to flashlight driver board for AVR ISP programming]]Some drivers have an Atmel microprocessor on board to control different modes. This microprocessor controls the number of modes, the brightness of the modes, the different flashing modes (strobe, SOS, etc.), mode memory, and low battery warnings. Atmel processors are programmable therefore the same driver can be loaded with different settings to customize the light with whatever features you want. This page will summarize some of the things you will need if you want to program your own drivers. This is based on a [http://budgetlightforum. | [[File:Avrisp.jpg|thumb|200px|SOIC 8 clip attached to flashlight driver board for AVR ISP programming]]Some drivers have an Atmel microprocessor on board to control different modes.

This whole thing was started by a BLF member, Tido. | ||
All of this is based on AVR tools developed for Atmel chips, which is mostly open source (free). [http://en.wikipedia.org/wiki/Atmel_AVR Wikipedia article]. ISP means "In System Programming," in other words, the chip can be reprogrammed while still soldered in place. | All of this is based on AVR tools developed for Atmel chips, which is mostly open source (free).
