    Level detector? ---> PIC Comparator

    OR, PIC16F785 i've ordered a thousand of them yesterday, sOOOO much nice stuff on-board... built-in OP-AMP, 2 phase PWM + asynchronous feedback as a teaser...

    NEW TOY, NEW TOY
    PIC16F785 What do you like best about them? The op-amps? What type of projects will you use them for? Should we all get a bunch just to keep up?

    Ohm it's not just a good idea... it's the LAW !

    Opamp is a REALLLY nice feature, i wasn't aware it was existing in one PIC.. but only voltage comparator & ADCs. Sure you could hack the voltage comparator with some feedback resistor, but my tests never give any good results... well not even close of what you should have with a op-amp.

    The Asynchronous PWM feedback (and 2 phase PWM) could be nice for some DC-DC converter, Motor control and for sure, some others.

    2 full independant analog comparator.. is a nice feature as well. There's also the REFCON and VRCON register which seems to add some nice stufff...

    There's also something i want to test.. the built-in voltage regulator..

    Don't worry, i did'nt read the whole thing really carefully

    Down side.. no USART, no MSSP... Oups!

    For analog stuff and power management, i think it's a really nice PIC.

    Time will tell...

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