- Understanding GPIO analog and digital - Electrical Engineering Stack . . .
A GPIO pin is a 'general purpose input output' pin This is by default only high or low (voltage levels, high being the micro controller's supply voltage, low usually being ground, or 0V) But the levels of 'high' and 'low' are usually given as voltages as a proportion of the supply voltage

GPIO Speed is the maximum frequency the GPIO can produce Lower settings can save power Output type is whether the pin asserts highs and lows (push pull), or whether the output turns on the gate of a FET that is attached to the pin at the drain (Open drain)

图1 gpio学习框架 二、基本结构概述 首先对gpio的基本结构进行详细分析。了解gpio的基本结构对gpio的模块的静态全貌、运行机理、配置使用有很好的帮助，图2为stm32的5v容忍的gpio口内部基本结构图，图3为gpio的基本结构中各个模块部分的概述。
- What is gpio bank? - Electrical Engineering Stack Exchange
A GPIO 'bank' is a group of GPIO bits that can be accessed simultaneously by the CPU or DMA The number of bits in a group is usually limited by the size of the internal data bus, so for example an 8 bit MCU with 24 I O pins would need at least 3 GPIO 'banks'
- microcontroller - Push-pull open drain; pull-up pull-down - Electrical . . .
Ultimately, I want to configure various GPIO pins to use them in "Alternate Function" mode for read write access to SRAM Of all the GPIO registers available, I do not understand two: GPIO_PUPDR and GPIO_OTYPE which are respectively the "pull-up pull-down register" and the "output type register" For GPIO_PUPDR I have three choices:
- ESP32 GPIO [0] number 2 pin is reserved - Electrical Engineering Stack . . .
E (111) phy_comm: gpio[0] number: 2 is reserved I'm confused because GPIO 2 is not connected to anything Here is my schematic I have checked the pin physically on the PCB to check any possible soldering mistake that short between the pins and there is none Confirmed with my multimeter
- STM32 SWDIO SWDCLK pins alternative use after programming?
We are wondering if we can use SWDIO and SWCLK pins as GPIO(High z) after programming? Yes The Reference manual describes how to disable the SWD port and configure the pins for GPIO usage See 29 3 2 on page 967: And 6 3 2 on page 175: Can we re-program with SWD after setting high z? Yes There is actually not much magic happening here
