MISSINGLINK 8051 MP3 and CPLD Development Board
This board has an 8051 microcontroller and a MP3 decoder hardware. There is also an onboard Xilinx XC9536XL CPLD. Make it Play MP3s or use it as an 8051 development board or learn about CPLDs by writing your own HDL and downloading it into the CPLD. This board is designed to take advantage of as many FREE development tools as much as possible. Programming of the microcontroller flash in either Windows or Linux. Linux programming by BeyondTTL's FREE FLAP software tool. Compile C code in both Linux and Windows using the FREE SDCC compiler. Compile and build your HDL using Xilinx's FREE ISE WebPack design tools.
