Configuration process of EXTI external interrupt in STM32 and EXTI external interrupt STM32 external interrupt introduction Correspondence between external interrupt lines and 112 IO ports Each of the 112 IO ports can be connected to its own external interrupt line. Since there are only 16 external interrupt lines, every 7 IO ports use an external interrupt line, for example: PA4, PB4, PC4 Extended interrupts and events controller (EXTI) The extended interrupts and events controller (EXTI) ...

STM32CubeMX学习笔记（3）——EXTI (外部中断)接口使用 2021/01/12 · 1. 打开 STM32CubeMX 软件，点击“新建工程”. 2. 选择 MCU 和封装. 3. 配置时钟. RCC 设置，选择 HSE (外部高速时钟) 为 Crystal/Ceramic Resonator (晶振/陶瓷 谐振 器) 选择 Clock Configuration ，配置系统时钟 SYSCLK 为 72MHz. 修改 HCLK 的值为 72 后，输入回车，软件会自动修 STM32- external interrupt EXTI – Code World EXTI 23 interrupt / event lines, each GPIO can be configured as an input line, taking EXTI0 to EXTI15, there is another s...

Membrane Filtration – an overview | ScienceDirect Topics The mechanism of membrane filtration technology in detaining microorganisms is a combination of two phenomena: firstly, the effect of physiochemical interactions between the membrane and microorganisms; and secondly, the sieving effect. 102, 103 The microorganisms that are larger than the pore size of the membrane are retained, and in a similar way the membrane that is negatively charged retains the microorganisms through the repe...

Membrane Filter – an overview | ScienceDirect Topics Using a custom fabricated cellulose acetate membrane, Ryu et al. created a further type of coculture system where cells on either side of the membrane were in much closer contact through the membrane pores. 74 The porosity of the membrane was shown to be greater than 50%, while the membrane thickness was less than 500 nm for all the pore diameters fabricated (0.1-, 0.4-, and 0.9-µm). In comparison to track-etched membranes with simila...
