有客戶在產(chǎn)品的設(shè)計(jì)中,使用外部IC 的GPIO 通過連接NRST 引腳來對stm32 mcu 進(jìn)行復(fù)位控制時(shí),會(huì)遇到以下問題:IC 可以對MCU 進(jìn)行復(fù)位控制,但是芯片內(nèi)部的復(fù)位信號(hào)(如看門狗等)不能對MCU 進(jìn)行復(fù)位,甚至影響引腳功能.

研究一種智能掃地機(jī)器人。從硬件系統(tǒng)控制模塊設(shè)計(jì)到主要技術(shù)調(diào)試進(jìn)行了較詳細(xì)的闡述。以STM32單片機(jī)為控制核心與電機(jī)驅(qū)動(dòng)、紅外線路徑識(shí)別模塊等相互協(xié)調(diào)應(yīng)用。進(jìn)行電路搭建和程序編寫。實(shí)現(xiàn)了智能掃地機(jī)器人紅外線避障和自動(dòng)掃地功能,其清掃面積能達(dá)到約70%,清掃率約60%,很大程度受到自身機(jī)械機(jī)構(gòu)的限制,后期將對小車的機(jī)械結(jié)構(gòu)進(jìn)行完善。This paper studies an intelligent sweeping robot.From the hardware system control module design to the main technical debugging are described in detail.stm32 mcu is used as the control core to coordinate with motor drive and infrared path recognition module.Conduct circuit building and programming.The functions of infrared obstacle avoidance and automatic sweeping of intelligent sweeping robot are realized.Its cleaning area can reach about 70%and the cleaning rate is about 60%.Because it is limited by its own mechanical mechanism to a great extent,the mechanical structure of the car will be improved in the later stage.
