25 февр. 2015 г. · How to know which to choose from? and what is open drain and push pull? In the GPIO_PuPd, there are 3 settings to pick from GPIO_PuPd_NOPULL // ...

16 янв. 2021 г. · The push-pull mode means the output is either strongly pulled low to VSS, or strongly pulled high to VDD. The open drain mode simply stops driving the high FET.

15 авг. 2018 г. · All pins with the letters "FT" ("five-volt tolerant") or "FTf" in the "I/O structure" column are 5V tolerant, and can be pulled up to 5V.

28 апр. 2020 г. · Open-drain drivers can translate lower MCU I/O voltage to higher LED voltage. But there's a catch. The Problem with GPIOs: the Protection Racket.

18 мая 2022 г. · Open-drain depends on a pullup resistor to provide the high state, while the low state is actively created by a transistor.

5 нояб. 2023 г. · The two STAT pins are connected with an open drain circuit, therefore when they are "high", they are floating.

7 янв. 2019 г. · The idea is to use inverse logic: if the GPIO is HIGH, both ends of the internal LED are on 3.3V, therefore no current is flowing and the opto-isolator is off.

10 июн. 2016 г. · The UART Tx pin can indeed be set to Open Drain or Push-Pull by selecting the proper argument to the GPIOInit() function. I am working ...

15 мар. 2012 г. · Open drain is useful when multiple gates or pins are connected together with an (external or internal) pull-up. If all the pin are high, they are all open ...

17 мар. 2021 г. · The requirements for the peripheral are that the pin is configured as an open drain output and is only used to pull it down for 1 second. The ...
