Bored of always typing in the same password over and over again? Luca designed a board to tackle just that problem. It’s a USB composite device, featuring both a USB keyboard emulator and a serial port. You program the letter sequence for the keyboard to type via the serial port, then press a button on […]

SquareWear open source controller board
Ray reports he’s just finished working on a new open source wearable electronics controller board called SquareWear. It’s small (1.6″x1.6″) and has built-in USB port (used for programming the microcontroller, USB serial communication, and charging battery). It also has 4 on-board MOSFETs for switching high-current load (up to 500mA). The board is based on Microchip’s […]
USB HID Joystick
Kiran designed a USB Joystick based on the PIC18F14K50 microcontroller. It has 10 buttons and an analog Joystick that uses 2 potentiometers to describe X and Y movement of the stick. The firmware is based on the Microchip USB stack, using the HID device class.
HACK: Open source USB stack on MCP2200
Microchip has a new USB->serial converter chip called the MCP2200. We suspected they made this chip from a 20-pin PIC. The MCP2200 pinout is like other PIC uCs, and it has similar reset pin and internal voltage regulator circuits. We hooked up our trusty PICKIT3 and read the device ID. The MCP2200 was recognized as a […]
