双全桥步进电机专用驱动芯片( Dual Full-Bridge Driver )L298中文资料
L298N 为SGS-THOMSON Microelectronics 所出产的双全桥步进电机专用驱动芯片( Dual Full-Bridge Driver ) ，内部包含4信道逻辑驱动电路，是一种二相
和四相步进电机的专用驱动器，可同时驱动2个二相或1个四相步进电机，内含二个H-Bridge 的高电压、大电流双全桥式驱动器，接收标准
TTL逻辑准位信号，可驱动46V、2A以下的步进电机，且可以直接透过电源来调节输出电压；此芯片可直接由单片机的IO端口来提供模拟时序信号，
但在本驱动电路中用L297 来提供时序信号，节省了单片机IO 端口的使用。

L298N 之接脚如图9 所示，Pin1 和Pin15 可与电流侦测用电阻连接来控制负载的电路； OUTl、OUT2 和OUT3、OUT4 之间分别接2 个步进电机；input1~input4 输入控制电位来控制电机的正反转；Enable 则控制电机停转。

4.3 控制换相顺序
两相四线步进电机的四拍工作方式，其各相通电顺序为(A+,B+,A-,B-,)依次循环。(通电控制脉冲必须严格按照这一顺序分别控制 A,B 相的通断。)
4.4 控制步进电机的转向
如果给定工作方式正序换相通电，步进电机正转，如果按反序通电换相，则电机就反转。如：正转通电顺序是：（A+,B+,A-,B-, 依次循环。）则反转的通电顺序是：（依 B-,A-,B+,A+ 次循环。）
特别适合要求运行平稳、低噪音、响应快、使用寿命长、高输出扭矩的应用场合。
三、电机驱动问题
1)为什么要采用光电隔离的设计方案？
答：不用光电隔离的驱动模块坏了，可能会烧坏控制部分的电路(如 CPU 等)。用了光电隔离电路,输入与输出没有直接相连，不但可以保护控制部分电路的安全，而且还可以防止了电机的感应电压不能干扰控制电路，这样从而抗干扰能力强。

刹车模式的定义为：INA=H，INB=H，此时马达驱动端 OUTA 以及 OUTB 都输出低电平，马达内存储的能量将通过 OUTA 端 NMOS 管或者 OUTB 端 NMOS 快速释放，马达在短时间内就会停止转动。注意在刹车模式下电路将消耗静态功耗。

低压8位常电流LED接驱动器数据手册说明书

This is information on a product in full production.June 2018DocID13405 Rev 61/32STP08DP05Low voltage 8-bit constant current LED sink with full outputs errordetectionDatasheet - production dataFeatures∙Low voltage power supply down to 3 V ∙8 constant current output channels ∙Adjustable output current through external resistor ∙Short and open output error detection ∙Serial data IN/parallel data OUT ∙ 3.3 V micro driver-able ∙Output current: 5-100 mA ∙30 MHz clock frequency∙Available in high thermal efficiency TSSOP exposed pad ∙ESD protection 2.5 kV HBM, 200 V MMDescriptionThe STP08DP05 is a monolithic, low voltage, low current power 8-bit shift register designed for LED panel displays. The STP08DP05 contains a 8-bitserial-in, parallel-out shift register that feeds a 8-bitD-type storage register. In the output stage, eight regulated current sources were designed to provide 5-100 mA constant current to drive the LEDs.The STP08DP05 is backward compatible in the functionality and footprint with STP8C/L596 and extends its functionality with open and short detection on the outputs. The detection circuit checks 3 different conditions that can occur on the output line: short to GND, short to V O or open line. The data detection results are loaded in the shift register and shifted out via the serial line output.The detection functionality is implemented without increasing the pin number, through a secondary function of the output enable and latch pin (DM1 and DM2 respectively), a dedicated logicsequence allows the device to enter or leave from detection mode. Through an external resistor, users can adjust the STP08DP05 output current, controlling in this way the light intensity of LEDs, in addition, user can adjust LED’s brightness intensity from 0% to 100% via OE/DM2 pin.The STP08DP05 guarantees a 20 V outputdriving capability, allowing users to connect more LEDs in series. The high clock frequency,30MHz, also satisfies the system requirement of high volume data transmission. The 3.3 V of voltage supply is well useful for applications that interface any micro from 3.3 V. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor.Table 1.

HS98Z单板控制器说明书

一、概述控制器主机为Z-80单板机，4MH时钟，八位字长，采用浮点，整数运算，具有处理旋转，循环，自动短路回退，自动找边中心功能。

有断电保护功能，机内装有镍镉电池，不必调换，使机器能应付突然停电在条件允许时，应充分注意，防尘，防湿，防煤烟。

二、面板结构（见图一）8位数码管锥度步进状态LED和拖板步进状态LED分别显示锥度和拖板四个步进马达三相绕组的通电情况。

驱动五相电机时上下两排分别显示Y、X步进马达五相绕组通电情况。

键状态LED显示相就的键状态，比如，按一下高频键，“高频LED”亮，表示打开高频电源，反之表示关闭高频电源。

键盘上共有33个键，采用热键方式，即按一下某一个键就执行某项功能。

功能名称键名相同。

输入参数时比如补偿置L，则按[L]键，立即显示当前L值。

若在键盘上打入[7][0]，则可清除当前L值，而将输入L。

有些键是双档参数键，比如缩放比例键[A/B]，则第一次显示当前A值，并等待输入新的A值，这时键状态LED中的“档次”亮，表示这时双档参数键处于上档参数A的显示及输入状态，再按一次显示档前B值，并等待输入新的B值，这时“档次”灭。

表示该键处于“下档”状态。

键盘名称尽量采用中文标识，便于中文用户。

三、内存分配和管理计算机控制器内有32KRAM随机存取器，简称32K内存，分存储区，数据区。

存储区用来放置大量3B指令，可从键盘逐条输入，也可用电报机头编程器方式逐条输入，输入每条指令后可打[F]键作为停码。

使取用时至此自动停机。

数据区用来存放当前正在加工的线段的所有数据，包括3B指令（一条），补偿量，转角，缩放等参数。

请尤其注意区分内存全删、清零和复位的关系。

内存全删指全册存储区内的3B指令。

清零指全清数据区的数据，如补偿量，转角，缩放等等。

复位指中断现行操作，使计算机回到初始状态。

但不清数据，也不删内存。

因具有断电保护功能，32K内存中的数据，任何时候都不会因关机而清除。

起条/终条键用来指定向内存区放置或调用3B指令时的位置。

手创科技技术资料汇集(一)H桥电机驱动电路说明书

手创科技技术资料汇集（一）
手创科技拥有强大团队阵容，其中有多个成员曾参加飞思卡尔智能小车竞赛并获得全国一等奖、华南赛区一等奖等，参加过机械创新设计大赛取得广东省一等奖，同时有队员获得国家专利。

技术实力雄厚，愿与各位参赛选手交流比赛心得，广交朋友，追求一起进步。

永无止境。

（手创科技淘宝店：/）此资料汇集的驱动模块：
说起驱动，我们摸索了很久，相信电机驱动电路大家常用的是MC33886，几片并联的，我们以前也是这样，但芯片很热，不好加散热片，究其原因是芯片驱动电流小，内阻大所致。

根本办法是用场效应管搭建H桥来驱动电机。

场效应管具有内阻极小、开关速度快等诸多优点。

并且加散热片很方便.勿认为使用场效应管很困难，只要你去找找相关的资料，你就会知道场效应管是电压驱动器件，只要栅极电压稍高一点就能使管子导通，单片机P口输出的电压不太够，所以还要增加栅极驱动电路，可以用cmos与非门，例如CD4011，场效应管P管用IRF4905或者是IRF2907，N管用IRF3205，受到P管电流限制，最大电流为74A，加一小块散热片就行了。

不管什么电路，先把原理弄懂了再使用！
本电路输入电压5~15V，最大输出电流74A。

注意事项：
1、TO-220AB封装的场效应管从正面看1脚是G（栅极），2脚是D （漏极），3脚是S（源级），大功率场效应管漏极（D）和散热片是连在一起的，所以Q1和Q3、Q2和Q4可以安在同一块散热片上。

2、CD4011的14脚接VDD（7.2V）、7脚接GND（地）。

3、上拉电阻一定要接，不然会逻辑混乱。

(不过我们建议上拉接5v，防止烧坏芯片。

切记！！！)。
