Modifying and Adding to the Software
To modify and recompile this software, one must download a copy of the CodeWarrior software development suite (IDE) from
Freescale. The link to this software is:
http://www.freescale.com/CodeWarrior
The USB to SPI software transfers 8 bytes of data from the SPIGen.exe program, via USB, to the JW32 MCU. The definitions
of the 8 bytes can be found in the main.c program, and the actual transfer and decoding is done in the USB_driver.c program.
Comments are provided throughout the code to explain the operation of the individual routines.
Once the code is compiled (without errors), the CodeWarrior IDE provides a means to download the binaries to the P&E Cyclone
Pro programmer, via the MON08 port to re-Flash the JW32. The documentation for this process is contained in the CodeWarrior
suite of tools and the P&E documentation.
