开漏输出(Open-Drain Output)是一种电子电路的输出方式,通常用于数字信号的传输。在这种输出方式中,输出端可以被驱动为高电平或低电平,但只能输出低电平,不能输出高电平。这是因为开漏输出 2024-07-14 10:48:02 开集、开漏与推挽输出原理详解 为了让同学们更加清楚的了解开集、开漏与推挽输出,今天我们就详解这两...
5. 推挽输出模式(Push-Pull output mode) 当GPIO配置为推挽输出模式时,它将可以提供较高电平或较低电平输出,但不会产生中间状态。该模式适用于双向电路的输出控制,具有较高的灵活性,但功耗相对较高。 6. 开漏输出模式(Open-Drain output mode) 当GPIO配置为开漏输出模式时,它将可以提供较低电平,但不能提供较高...

The MCU is programmed to use only the HSI clock, one timer, the USART2 and the GPIO banks A and B. I have difficulties to figure out whether the board enters in stop2 mode at all. Another thing that I don’t understand is How the GPIOs interrupts can work if all the...
