    Sorry but i understand only english
    Here is the problem
    I have this Bascom program for control Saa1057 From a PDF
    But it has no frequency limits from 87.5 to 108 Mhz
    How to edit it to have this limits with no change display after push the UP and Down button when limits are reached.
    This code is tested and works 100% on Bascom 1.11.9.8

    Thank to all that can help
    If Flash is full when someone can make it with limits I can easy change the 4433 with Atmega8 . They are pin compatible . Just need to change the .def file. I guess Atmega8 Is no problem to work at 4 Mhz crystal?
    Also i want to know how Setup = 49605 is converted to .... '&B1100000111000101 and how can i convert my own code , because i want to change some bits

    Setup = 49605 this is the same Setup = &B1100000111000101

    Write Setup = &B1100000111000101 and change bits.

    I see now.....
    Ok the only thing is that with added tips from you the 4433 cannot fit all this to flash :)
    Shows me 100% but warning to overwrite . So the solve is to use the ATMEGA8
    Thank you and be cool man .

    P.S: Yep , I fit it on 4433 !!!! Just remove the first Welcome and SAA1057 PLL messages from the program !
    Yes!
