[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 ...

If you’re planning to do some hacking with CPLD or FPGA chips you’ll need a way to program them. JTAG is one of the options and here’s a cheap method that uses the serial port (translated). This ...

In Part I of this article, I briefly mentioned the generic USB driver in the context of getting a USB device to communicate through it easily, with no custom kernel programming. Unfortunately, I ...

The project allows the programming of a PIC in circuit while avoiding the need to constantly take in and out of the programmer with the bending of pins subsequently. The project allows the programming ...
