Web27 mrt. 2024 · I believe that GPIO is configured as input function with internal weak-pull up resistance when the MCU is in reset state. Hear "reset state" means that the MCU's reset pin is low. Therefore, I consider placing an external pull-down resistance on the line and I'd like to know the resistance value of internal weak-pull up to calculate the appropriate … Web19 mrt. 2024 · I2C outputs are open-drain, but internal pull-ups are too weak to use with I2C pins, they are in the order of tens of kilo-ohms. I am not saying that it does not work, it will just be extremely slow if it works, and not within rise time specs. – Justme Mar 19, 2024 at 14:33 Show 6 more comments 2

FT and TT I/Os have options depending on the device. The user must refer to the datasheet for their definitions. Web27 jun. 2016 · The pull-down resistor holds the logic signal near to zero volts (0V) when no other active device is connected. It pulls the input voltage down to the ground to prevent an undefined state at the input. It …
Web25 okt. 2013 · The circuit below shows a GPIO pin with a weak internal pull-up resistor–most modern microcontroller designs have built-in pull-up and/or pull-down resistors on each GPIO pin–and a strong external pull-down resistor. For the strong pull-down resistor to work properly, it must be correctly sized. Web3 mei 2024 · 1 Answer Sorted by: 1 It only has an effect on the output when the pin is in tristate.
