Fix for CrossView Pro error: "Library not found: SIM251.DLL"
The actual file missing is not SIM251.DLL but MSVCRT40.DLL. Unzip and copy this file into your 251\BIN or C:\WINDOWS\SYSTEM directory.
Demo key for USB examples
This is a key file that allows you to build the 8x930 USB examples from 8x930.zip when using the v20r0 demo of the 251 compiler package. When copied to its d251\etc directory the examples 'usb' and 'function' will build without an error telling you that the package has exceeded its limits.
Sample USB C Code for 251 Intel USB derivatives
Sample C code for the Intel 8x930 USB evaluation boards. It contains firmware code compliant to the USB specifications chapter 9 and 11. You can test the USB devices with the Compliance Tool for Win98, available from the USB developers website. You can build and debug the application using the TASKING 251/930USB Power Package (requires version 2.0 or up). There are three types of projects for each micro controller, a hub, a function and a compound device. For the hub and the compound device, you need an 8x930Hx adapter board and for the function, you need an 8x930Ax adapter board.
This Intel example contains sample assembly code for the Intel 8x930 USB evaluation board. You can build and debug the application using the TASKING 251/930USB Power Package (requires version 2.0 or up). The application converts the board into a true HUB and allows USB functions to be connected to it. If you connect the USB cable to the board running this application, Windows will automatically load the "Generic USB Hub" driver. Please note that the board must be equipped with a 8x930Hx (Hub) controller or daughterboard (not 8x930Ax).
