8751 to be erased ( with UV ) and Programmed.

Do you want to continue ?

If YES, search for the Programming algorithm with Google; Get UV eraser ;Erase the chip; Arrange for programming voltage; Hardwire the FPGA to act as a programmer after you know how to; Program the 8751; Hope and Pray it works.

If NO go to E-Bay ( or whatever it is ) buy a Flash MCU like the 89c51rx2; Download Flash Magic for free from www.esacademy.com; Start writing code in your favourite assembler / compiler and download via RS232 into the chip - to your hearts content. And save the FPGA for a rainy day...

Enjoy.
