USB Overview

The device we've developed is centered around Microchip PIC18 F4550. Using the power of this microprocessor, DTI has developed a cutting edge API to develop flexible I/O devices rapidly. Using a modified bootloader, the devices are capable of reprogramming their embedded firmware quickly via a USB connection.

These devices can adapt to operate in "stand-alone" mode if connection to the client application is lost or even as an intended mode. 

USB Device Features List

Currently our devices are able to do the following tasks: USB Connection Digital I/O (this can be leveraged to do physical tasks) Wiegand Communication Matrix Style Keypad Input "On-the-Fly" Firmware upgrades Memory Storage

USB Device Schematics

This is the schematic to the heart of our devices. This can be attached to custom boards that utilize digital and analog I/O signals to perform physical actions and monitor real world statuses.
