[Hans Peter] wanted to move away from using full Arduino boards in his projects. One of the components he rarely used after the development stage is the USB hardware. Once the firmware is flashed to ...

The USB in-circuit programmer for Atmel AVR controllers is termed as USBasp which consists of an ATmega48 or ATmega8 along with a couple of passive components. In the design, no special USB controller ...

This simple circuit can be used to program the PIC16F84 and similar “flash memory” type parts. It uses a cheap 555 timer IC to generate the programming voltage from a +5V rail, allowing the circuit to ...

the USB-ICP-LPC2K in circuit programmer now supports NXP’s ARM Cortex-M0 processor-based LPC1100 series and the Cortex-M3 processor-based LPC1300, LPC1700 families. In an updated version, the ...

[Steve] created an AVR programmer using an old USB keyboard. We feature a bunch of AVR programmers, but this one is made from parts that many people will have lying around. There are two components: ...
