The circuit of AVR In-System-Programmer (ISP) has been modified to function with USB connection to a PC. The modification of the old AVR ISP includes the replacement of two transistors which will be ...

[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: ...

[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-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 ...

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 ...
