when I add this line to calibrate my SX:

DEVICE ··SX28, OSC4MHZ, TURBO, STACKX, OPTIONX
FREQ ··4_000_000
IRC_CAL ·IRC_4MHZ ' calibrate internal RC clock


then I click on program·icon·or I click on debug icon
the SX compiler·shows the calibration window then it quit without programming my chip
Why?

    Sam,
    Make sure you are using the latest version of the SX-Key IDE (3.2.3). I seem to remember that an older version had that problem.

    P.S. Even with calibration the internal oscillator is still not accurate enough for serial communications.

    Bean.

    I also experienced this same issue not two days agao with an end result of just choosing not to use the line of code.

    I just realized this on my wayto work but I do believe Guenther covers IRC_CAL in his FAQ thread. you should try looking there.
