Beyond Logic Source Code & Driver for Cypress USB Starter

Includes IOCTL MAP and PDF Documentation of IOCTL Calls.

This is a modified version of the WDM ISO USB driver distributed with the Windows Device Driver Kit for use with the Cypress Digital Themometer.

The driver is simply the ISO USB driver featured in the Microsoft DDK with modifications in IsoUsb_CreateDeviceObject so you can talk to the Kernel Mode Device Driver using ".Thermometer_0". This allows the Cypress application to talk to the driver, rather than using the GUID which Microsoft uses in their example.

The IOCTL handler has been totally modified to handle calls from the thermometer application which comes with the Cypress Kit. This allows you to run the Cypress Thermometer Application on this device driver. It includes all the IOCTL Control Code 4 Functions such as Set LED Brightness, Read Thermometer, Read Port, Write Port, Read RAM, Write RAM & Read ROM as per the Cypress Starter Kit.
