#87870 - I'd still let the PC do it! Responding to: ???'s previous message |

But their on byte write time 5 msec so writing 128k bytes each time will take more 5 minutes. Nobody said he has to write the whole EEPROM! Just get the PC to format & write the data as one simple, contiguous, data structure. Doesn't matter if it doesn't fill the EEPROM. And he has to write code in C at PC side to manipulate those 128 k bytes data in PC - same C code he can use on MCU side) Yes, with care the code could be written to work on both PC and 8051 - but it would have to be constrained by the lowest common denominator; ie, the 8051. The point of getting the PC to do the "hard" work is that you are then not constrained by the limitations of the 8051 - you can malloc, or use C++ and do new and all that stuff to your heart's content on a PC. And linked list File system I have suggested is very easy to implement (though its look complicated in explanation). Yes - not difficult, but equally not necessary! And, relative to a simple, contiguous, data structure, it is much more complicated. |
