对发送标志位清0。调试要点与实验现象接好硬件，通过冷启动方式将程序所生成的。hex文件下载到单片机运行后，打开串口调试助手软件，设置好波特率1200，复位单片机，然后在通过串口调试助手往单片机发送数据(见)，可以观察到在接收窗口有发送的数据显示，此外电路板上的串行通信指示灯也会闪烁，P0口所接到LED灯会闪烁所接收到的数据。串口软件调试界面另外串口调试助手软件使用时应注意的是，如果单片机开发板采用串口下载而且和串口调试助手是使用同一串口，则在打开串口软件的同时不能给单片机下载程序，如需要下载，请首先点击“关闭串口”，做发送实验的时候，注意如果选中16进制发送的就是数字或者字母的16进制数值，比如发送“0”，实际接收的就应该是0x00，如果不选中，默认发送的是ASCII码值，此时发送“0”，实际接收的就应该是0x30，这点可以通过观察板子P0口上的对应的LED指示出来。
钢带铠装主要是作为电缆的径向机械保护层，同时它也起到附加性总屏蔽作用，特别是钢带铠装和铜丝、铜带屏蔽，是采用了两种不同屏蔽材料，在电磁波屏蔽上起到一定的互补作用，屏蔽效果将更好。性能设计与参照标准1.8／3千伏及以下变频电机专用电缆电气性能均按GB／Tl2706，2002标准设计。

Purpose: the self-supporting non-filled cable is suitable for the urban and township telecommunication lines of local telecommunication network, and also for the special network lines connecting to the public network. It is economical and practical to use the same outer protective layer for hoisting line and cable. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter is 0. 4, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 mm. Insulating material: high density polyethylene or ethylene-propylene copolymer. The color of the insulated wire is in accordance with the full chromatographic standard. Pair of insulated wires: two different colored insulated wires are twisted in pairs according to different pitch and are identified by a specified chromatographic combination. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs or more of cables plus 1% of the reserve pair. Core tape: wrap with a polygrease film tape. Shielding: the two sides are overlapped with or without corrugated metal strip, beyond the cable core of the longitudinal capsule. The plastic film coated on the surface of the shielding belt and the bonding sheath of the protective layer: black low density polyethylene. Hoisting line: the hoisting line is 7 strands of galvanized steel strand, nominal outside diameter is 6. 3 and 4 mm. The tensile strength of two types of 75mm is not less than 3000kg and 1800kg respectively. The suspension wire is coated with thermoplastic paint to prevent the steel wire from corrosion.

因此已逐步代替碱性电池。但由于电池的技术壁垒高，知识专利成本高，故国内锂铁电池品牌以耐时电池占比最大，且由于售价方面相对碳性和碱性电池来说要高，故在一般的商超也很难买到，仅天猫有售。镍镉电池前面说的几款都是一次性干电池，用完之后就报废了。而镍镉电池属于可充电电池的一种，具有放电电流大、低温放电性能**、不漏液、内阻低的优良特性，且售价属于便宜的充电电池，这些优点让镍镉电池看起来用在智能门锁上很合适，实则不然。
