舵机调试程序舵机控制信号管脚,为P0.7管脚 系统时钟为24500KHZ/8=3062.5KHZ周期为20ms，则频率为50HZ，则tmph+tmpl=61250可以保证产生50HZ PWM-Steering gear steering gear control signal debugger pin for system clock for the P0.7 pin 24500KHZ/8 = 3062.5KHZ period of 20ms, the frequency is 50HZ, the tmph+ Tmpl = 61250 can guarantee have 50HZ PWM

FreeRTOS，这个比 Real Time Linux 和 eCos 更小的实时操作系统，并且你也不用为这两个大的操作系统弄得头大了。FreeRTOS是一个非常小的实时操作系统，它包含有一个实时的内核及一个内核调制程序。它支持的单片机有 Philips ARM7, TI MSP430, Renesas (Hitachi) H8/S, Atmel AVR, Motorola/Freescale HCS12, Motorola/Freescale ColdFire, 及其他8051的单片机--FreeRTOS, an OS smaller than Real Time Linux and eCos. It is a very small real time operating system. It includes a real time kernel and a kernel configuration program.Its supported SCMs include Philips ARM7, TI MSP430, Renesas (Hitachi) H8/S, Atmel AVR, Motorola/Freescale HCS12, Motorola/Freescale ColdFire, and other 8051 SCMs.

详细介绍RS-485/422原理与区别、元件选择、参考电路、通讯规约、程序设计等方面的应用要点，以及在产品实践中总结出的一些经验、窍门-Detail the difference between theory and RS-485/422, component selection, reference circuits, communications statute, procedures for the application of design elements, as well as practice in the products sum up the experience, know-how

这是使用MAX3100和89S52单片机的红外放射原理图和用C语言写的程序代码。-This is the use of MAX3100 and MCU 89S52 Schematic infrared radiation and the use of C language to write the program code.

MCS-51单片机有5个中断源，其中两个是由-INT0、-INT1引脚输入的外部中断源；另外三个是内部中断源即由T0、T1的溢出引起中断和串行口发送完一个字节或接收到一个字节数据引起中断。触发外部中断有两种方式，即下降沿引起中断或低电平引起中断。当编程TCON中的ITi（i=0、1）为1时，则引起触发的方式为边沿触发方式，反之(ITi=0)为低电平触发方式。每个中断源的中断请求能否得到响应要受两级“开关”的控制，即一个总“开关”-MCS-51 single-chip has five interrupt sources, two of which are by-INT0,-INT1 pin input external interrupt source the other three internal interrupt sources from the T0, T1 overflow caused by the disruption and serial port sending or receiving end of a byte to a byte of data caused by interruption. Triggered external interrupt has two modes, namely, falling edge or low-level disruption caused disruption caused. When programming TCON in ITi (i = 0,1) for the 1:00 has been the subject of a way to trigger the way to the edge of the trigger, on the contrary (ITi = 0) for low-level trigger mode. Each interrupt source interrupt request can be subject to levels in response to
