    Re: Wire guide & H-bridge control

    well, according to the datasheet the A1302 should work fine for your application.
    5V only though, but it's linear 1.3 mV/G so for every 1.3mV on its output you have 1 gauss... if you used a 4V...

    Re: Wire guide & H-bridge control

    Hi RFsolution,
    With line following robots, they have inputs from both (or all) sensors so that they know if they are way too far over.

    From your description you have 4 distinct zones of control....
  20. Re: Can you use the same pin as input/output and control led load?

    I believe most pic16's and PIC18's have a 20mA source or sink limit so a resistor on the pin would not be required.
    So FromTheCockpit's diagram above will work, though you will not get 5V to feed...

    Re: 18F46K22 HPWM blips and errors

    Henrik,
    I agree with you that it must be the HPWM command that is causing the blips since the 46K22 has a buffered PWM.
    However, as you can see from the source code, i do most things by setting the...
