WebThe pins can be configured to use built-in pull-up or pull-down resistors, except GPIO2 (board pin number 3) and GPIO3 (board pin number 5), which have fixed pull-up resistors. The GPIO pins output 3.3 V for logical HIGH and 0V for logical LOW. They read 3.3V as logical HIGH and 0V as logical LOW. WebOct 2, 2014 · In this way, the default value of the input can be set. It is possible to have pull up/down resistors in hardware and using software. In hardware, a 10K resistor between the input channel and 3.3V (pull-up) or 0V (pull-down) is commonly used. The RPi.GPIO module allows you to configure the Broadcom SOC to do this in software:

WebWhen an input pin is considered active depends on the value passed to the pull_up_down argument. There are two possible values. GPIO.PUD_DOWN - The input is considered active if it is receiving +3.3V, inactive otherwise.; GPIO.PUD_UP - The input is considered active if reading less than +3.3V, inactive if it reads +3.3V.; The table below further clarifies the … WebMay 20, 2024 · OpenPLC raspberrypi.cpp driver activates PUD_DOWN (internal pull down circuitry) for all pins except %IX0.0 and %IX0.1 because they are pulled up in hardware. If you want all the pins to have the same behavior as %IX0.0 and %IX0.1 you will need to change that line of code that says PUD_DOWN to PUD_UP.
