    Default EEPROM Transfert with Serial Communicator

    I must transfert an entire 256K I2C EEPROM to my PC. I currently use Serial Communicator included with PicBasic. My PIC send 16bit value as ASCII characters. Since I use 16bit value, I should be limited to around 16000 value. Can a terminal support that large number of value? I ask you because at around the 3/4 of transfert, the Terminal freeze, while the PIC continue to send value...

    It was working well with 5000 value, but now I can't get my precious value to Excel because I record until the end of the EEPROM.

    I'm also trying to make a small terminal with VisualBasic, is it a good idea? Will I have the same problem. By this, maybe I could write directly the values to a file...

    mmm, interesting. What about if you do a pause sometimes to give some time to the PC to empty his buffer?

    Those programs i did with VB take a X amount of bytes, proceed them, send a message to the PIC to continue dumping, then rebegin.

    As now, no problem at all. Even if dumping MBs of Data.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Since I use the intrc oscillator, I'm limited to 2400 bauds. Between each value there's a 20ms of EEPROM reading. I'm sure that the computer can take that!

    well try RealTerm or maybe the crap windows Hyperterminal could also work

    Realterm => http://realterm.sourceforge.net/

    Have a look to the following link. It explain how to use RealTerm in Excel
