The problem I have is that the PC program probably... What do you mean, "probably"? You need to be certain about this before you proceed! ... specify to load characters to AT89S8252 memory access at address 2000h - FFFFh, but AT89S8253 has the memory address access at 3000h-FFFFh. Therefore, I could not use that PC program to program to the new AT89S8253. I am thinking to modify the code in RxTx section (attached) to write the received data (from PC) to the new memory address 1000h above the specified address. But what happens if the PC program spcifies an address of F000 or higher... Obviously, what you really need is to get the PC programm re-written to correctly support the new hardware... |
