  +url: "https://electronics.stackexchange.com/q/670924/107963"
  +body: """
    Solution\n
    --------\n
    \n
    Using an open drain buffer like the `74LVC1G07` did the trick. Note that this part only works for inputs with a pull-up resistor. There are other parts from the same lineup that can work with any input.\n
    \n
    Problem\n
    -------\n
    \n
    > I have an ebike computer that has two inputs that accept square wave signals. The range is 0-5V. One of the inputs has no pull-up/down resistors on it. When I hook up a device producing signal, the signal is detected correctly. Both highs and lows are detected correctly. The other input has a built-in pull-up resistor. When I hook the same signal to it, only the high side is detected. Measuring the voltage of the low side, it's a bit higher than when hooked to the other input and I'm guessing it isn't crossing the low threshold the computer expects in order to register the low.\n
    \n
    > Am I right in thinking that the pull-up resistor is increasing the lows?\n
    \n
    > Is it possible to counteract the internal pull-up resistor by hooking a pull-down resistor to the input?\n

        I measured the signal generator alone, not connected to the input. It goes to 4.5V high and 0.001V low. Then I connected it to the input and measured at the input. I got 4.5V high and 1.1V low.\n

        I measured the signal generator alone, not connected to the input. It goes to 4.5V high and 0.001V low. Then I connected it to the input and measured at the input. I got 4.5V high and 1.1V low.\n
        \n
        Also I ordered the 74LVC1G07 buffer along with a breakout board which should allow me to hook it up inline and test. I'll report back when I do.

    +url: "https://electronics.stackexchange.com/q/670924/107963"
    +body: """
      Solution\n
      --------\n
      \n
      Using an open drain buffer like the `74LVC1G07` did the trick. Note that this part only works for inputs with a pull-up resistor. There are other parts from the same lineup that can work with any input.\n
      \n
      Problem\n
      -------\n
      \n
      > I have an ebike computer that has two inputs that accept square wave signals. The range is 0-5V. One of the inputs has no pull-up/down resistors on it. When I hook up a device producing signal, the signal is detected correctly. Both highs and lows are detected correctly. The other input has a built-in pull-up resistor. When I hook the same signal to it, only the high side is detected. Measuring the voltage of the low side, it's a bit higher than when hooked to the other input and I'm guessing it isn't crossing the low threshold the computer expects in order to register the low.\n
      \n
      > Am I right in thinking that the pull-up resistor is increasing the lows?\n
      \n
      > Is it possible to counteract the internal pull-up resistor by hooking a pull-down resistor to the input?\n
      \n
      > I'm a software guy with decent soldering skills and minimal knowledge in electronics so please answer like I'm not the brightest electronic bulb on the tree.\n
      \n
      > Thank you in advance!\n
