Mar 5, 2021 · i try to implement an input which is reacting on an high impedance 3.3V on PC14. My Configuration looks like this. main.h #define I_Pin GPIO_PIN_14 #define I_GPIO_Port GPIOC …

May 1, 2021 · I'm interested in designing a "simple" circuit that would bridge digital inputs or outputs over a distance with relatively low latency. The idea is to take several pins from a GPIO bus like

The GPIO pins on most FPGAs will be bidirectional, just like those on an ATMega (Arduino board MCU). For an FPGA, you simply need to describe the logic for a tri-state buffer to be able to control the …

Reading through the STM32F051 manual, it looks like it's possible to configure the same alternate function on two pins; for example, you could have multiple USART1_TX pins at the same time. Or for

Apr 9, 2013 · What's the maximum amount of current which I can draw from each of the Arduino's pins without tripping any of the internal fuses? Is there a limit per pin as well as an overall limit for the …

Dec 31, 2021 · GPIO (General Purpose Input/Output，通用输入输出接口)，是单片机中最基础的外设，它直接表现为芯片的一个个引脚裸露在芯片外，是单片机与外部设备进行双向数据交换的必由之路 …

I started studying interrupts on stm32 specifically the stm32f4 discovery board. i found this example in which you have to press the button to start the interrupt and push it again to stop it. In t...

Jan 30, 2025 · I am making measurements for the characterization of pull-up and pull-down resistances in microcontrollers GPIO interface. I am currently working on a STM32 microcontroller, and in …

Mar 26, 2012 · In the manual of my STM32, one of the GPIO Alternate Functions (namely AF15, see page 138) is called EVENTOUT. At no point is the event defined, or a use case given.

Feb 18, 2025 · I am trying to take a digital input from pin B12 (PB12) to control the internal LED of the STM32 Blue Pill (STM32F103C8T6) board at pin C13 (PC13). The B12 pin is set to High-Z mode. …
