MSP430单片机对步进电机的驱动控制设计

单片机实现的步进电机控制系统具有成本低、使用灵活的特点，广泛应用于数控机床、机器人，定量进给、工业自动控制以及各种可控的有定位要求的机械工具等应用领域。步进电机是数字控制电机，将脉冲信号转换成角位移，电机的转速、停止的位置取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，非超载状态下，根据上述线性关系，再加上步进电机只有周期性误差而无累积误差，因此步进电机适用于单片机控制。步进电机通过输入脉冲...[详细]
低功率能量采集技术助力传感器寿命更持久

现今无线感测器节点大多使用电池供电，因此建置完成后仍须耗费庞大的人力和物力成本进行维护；而具备低功率能量採集技术的感应器，则可实现几乎无止境的运作，能显著节省维护成本，特别是当此一感测器是被装置在人烟罕至的地区时。智慧型环境意味著未来家庭与建筑物的自动化。这些自动化须仰赖各种不同的感应器、控制器及致动器，这些元件扮演多元角色，并分布在整个环境中，而这样的分布形成了一些技术挑战。举例来...[详细]

浅析防腐型磁翻板液位计内衬工艺难在何处

防腐型磁翻板液位计，通常应用于测量强腐蚀性介质的液体，这种磁翻板液位计要具有可靠的防腐性能，需要采用304不锈钢内衬聚四氟乙烯（PTFE)并结合先进的内衬工艺加工而成。使用聚四氟乙烯（PTFE)作为内衬是由于聚四氟乙烯（PTFE)具有优良的化学稳定性和耐腐蚀性，是当今世界上耐腐蚀性能最佳的材料之一，有“塑料王”的美誉，适用于强酸、强碱、强氧化剂，几乎不溶于所有的溶剂，在王水中煮沸也不起变化。但防...[详细]
iPhone潜望镜相机可提供光学图像稳定和自动对焦功能

无线感应充电新技术将解决电动汽车充电难题

随着电动汽车的兴起，充电桩开始在全国各地陆续开建，配备有充电设备的充电站及换电站已经开始示范运营，但是相应的问题也涌现出来。充电时间长，覆盖范围小，蓄电池安全隐患无一不是用户担心的问题。如果电动汽车用户想在自己家中或者车库里实现这个过程，却未免有些麻烦。因此，一种名为无线感应充电新技术开始受到青睐。　　在德国Starnberg的一个电动车充电站里，技术服务公司TüV南德意志集团和能源公...[详细]
台积电战将三星14nm功臣梁孟松传将加盟SMIC

半导体业界公认不爱名利的前台积电共同执行长蒋尚义，赴大陆担任中芯国际独立非执行董事，震惊业界，然业界又传出投奔三星电子、与台积电打官司多年的前台积电资深研发处长梁孟松，已于第3季离开三星，近期将投入大陆半导体舰队，落脚处也是中芯国际。业者认为这些台湾半导体超级战将纷投效大陆，似乎是为大陆半导体未来黄金十年做背书。大陆大动作发展半导体产业，继疯狂盖12吋晶圆厂、购并国际大厂，近期开始挖角重量级的...[详细]

什么才是智能车该有的样子？一篇看懂上海车展汽车黑科技

逛了两圈上海车展，给我留下最大的印象就是，燃油车再也抢不到头条了，所有重磅内容都偏向电动车与自动驾驶，当然，还有华为inside、大疆车载和一直不缺乏热搜的特斯拉。都说2021年是自动驾驶元年，那么自动驾驶真的能如期所知么？智能汽车该有的样又是什么呢？激光雷达正式上车　　目前大多数的智能辅助驾驶技术还称不上真正的自动驾驶，L3级别这个鸿沟似乎很难迈过去。之前诸多车企，像特斯拉、小鹏、...[详细]
丰田演示使用路车间及车车间通信技术

丰田在2012年11月中旬举行的“安全技术说明会”上演示了使用760MHz频带的路车间及车车间通信技术，凭借一个车载设备实现了路车间和车车间通信。　　760MHz频带是日本随着数字电视开播而空出来的频带，日本总务省将其分配给ITS用途。该用途也可使用5.8GHz频带，但760MHz频带更容易发生衍射，因此便于在十字路口等处来使用。丰田在东富士研究所院内建成了路车及车车间通信技术实验场...[详细]
用简单电路来指示信号的逻辑

文中的电路可以让用户知道信号是逻辑高还是逻辑低。当输入为“1”(逻辑高)时，共阴极显示屏显示“H”，但输入为“0”(逻辑低)时，显示“L”。该电路利用了IC(7400)四个门中的一个，来转换输入并通过射极跟随器T1将输出施加在显示器的d,e,f段。二极管和电路通过射极跟随器对直接和非直接的输入进行缓冲，来分段e,f. 这个电路工作在5V电源电压下。 ...[详细]
