    Re: Upgrating to PBP3.1

    OK.
    I’ve already paid for my PBP3.1 and MCSPX-Full and got my activation keys.
    I do not have yet a laptop ready for the installation but I will hopefully get one this week.
    In mean time, I’m...

    Hi Team,

    I’ve started the countdown to retirement and the first move will be to finally upgrade to the latest PBP.
    So far, I’ve been successfully using older PBP revisions with older free...

    Thank you Henrik for the extra information.
    In my case it should be simple since I’m using an old fashion chip (PIC16F819).

    Thanks, Tumleweed.
    Are we are talking all configs only?
    The defines can and will be programmed by the new .HEX file. True?

    No Henrik, as usual I'm wrong.
    Sorry for false alarm.

  14. Re: Measuring duty cycle of short duration pulses with long period

    I’m not sure how much this will change things but shouldn’t maximum period expected be 20 ms not 200 ms?
    And if it is so, should the timer setup be changed or it will still work?

    Re: TEC controller

    This is the latest addition to the TEC controller: One pot on ADC1 sets the temperature.
    I’ve done it such way so with a linear pot the target temperature can be set between 40 and 65 degrees F.

    This might be one of the improvements that I thought about too, in case this first minimal approach will not work.

    Re: TEC controller

    This is the working code. It steps up through 21 steps of PWM (from 30 to 50) and then steps down (from 50 to 20). The result is an output voltage between 5.5V and 8.5V (the numbers are rounded up)....
