This project requires some hardware for microprocessor, software for microprocessor and website. Minimizing hardware cost is the highest priority.
Allow Microchip PIC microprocessor to connect to PC via USB port and exchange data with a website. It is preferred that this is accomplished without requiring installation of drivers (use standard HID or other generic drivers included in Windows). The microprocessor device is very cost sensitive. FTDI and most other USB binder chips are too expensive so we seek very a inexpensive method of binding Microchip PIC to a PC USB port.
The PIC microcontroller will be used as a portable time and temperture datalogger in outdoor applications. Typically the user would bring the device into a laboratory from the field, connect the to a PC then log on to a website. On the website there would be an "upload" button which would allow the user to find and select the device. Upon device selection data can be exchanged between website and microprocessor. Data would typically consist of a 64 bit id number, date, time, and up to two thousand 32 bit numbers. This project requires some hardware for microprocessor, software for microprocessor and website.
