  • MODBUS RTU 51与维纶触摸屏例程。
    应用背景51和维纶触摸屏的通信。MODBUS RTU 51与维纶触摸屏通信例程。支持的功能码:位:01(读)、05(写),字:03(读)、06(写)还有与数码管显示输入的数据!注释的也比较详细。个人觉得移植性也比较好。各种的单片机上可以移植修改,关键技术51单片机与威纶通触摸屏通讯说明 本程序仅作为一个通信示例程序,实际使用需要根据需要修改。 请使用EB8000 V3.45以上软件打开触摸屏程序,程序为压缩后的触摸屏程序,请使用EB8000软件 工具——压缩/解压缩 菜单下的工具先进行解压缩;单片机使用Keil uVision3 V3.50编译 一、硬件连接    使用ATMEl 89S52单片机。 二、软件 1、通讯环境 触摸屏设置为主站,即PLC 类型 MODBUS RTU,通讯参数设为“9600,N,8,1”。 2、触摸屏程序,需要读取八个位,以及八个字,每次最少读取16个位,字可以一次读取一个也可以一次读取八个。 有0X1-0X8八个位切换开关,6X1-6X8八个字输入元件,支持的功能码:位:01(读)、05(写),字:03(读)、06(写) 当没有写操作时,屏不断的向单片机发送如下码(16进制显示): 01  01  00  00  00  10  3D  C6  (位读取) 01  03  00  00  00  08  44  0C  (字读取) 此时,如果不给屏发送相应返回值的话,屏就会提示“PLC no response” 3、51单片机程序思路及说明

    SYMPCHUNK sets the number of symbols demodulated at once with a constant carrier frequency and symbol timing offset. This is a fundamental decoder parameter that establishes its carrier and symbol timing tracking bandwidth. Set it too low and the demodulator can"t accurately determine carrier frequency and symbol timing on a noisy signal. Set it too high and the demodulator may not be able to track large symbol rate offsets caused by Doppler shift and/or A/D or spacecraft clock errors. Or it might have trouble tracking high rates of change in the carrier frequency due to Doppler acceleration.The current value of SYMPCHUNK is 4*N1 = 512, where N1 = 128 is the order of the convolutional interleaver. 512 symbols is 512 milliseconds at 1000 symbols/sec, giving a frequency/time determination SNR that is 10*log10(512) = 27 dB greater than the Es/N0, not counti
