stm32 GPIO初学 stm32GPIO口 在这里我们重新认识下stm32f10x的GPIO口,每个GPIO口都有32位配置寄存器(GPIOX_CRL,GPIOX_CRH),两个32位数据寄存器(GPIOx_IDR和GPIOx_ODR),一个32位的复位、置位寄存器(GPIOX_BSRR),一个16位的复位寄存器(GPIOX_BRR)和一个32位锁定寄存器(GPIOX_LCKR)。 端口位配置表输出模式...
存储器两种编址,分别为独立编址、统一编址配置 GPIO管脚的时候,常会见到两种模式:开漏( open-drain,漏极开路)和推挽( push-pull),解释这两种工作
**MCU的GPIO输出模式Open Drain & Push/Pull的理解**【Push-Pull推挽输出】原理:输出的器件是指输出脚内部集成有一对互补的MOSFET,当Q1导通、Q2截止时输出高电平;而当Q1截止导通、Q2导通时输出低电平。Push-Pull输出,实际上内部是用了两个晶体管(transistor),此
Is it possible to use GPIO described as "Push pull" in Open Drain? On the Host Interface Guide, only USB3_Event_Port1 had Open Drain and the other two were Push pull. There are check Open Drain output box on the customization tool are they consider to use it as Open Drain o...
