CPU-5CE/16-85-2 FORCE软件完结
ATmega48芯片具有4 KB内部Flash和512字节的片内SRAM,软件完结需考虑资源分配问题,特别是SRAM使用情况。由于程序触及串口通讯、DTMF通讯和FSK通讯3种情况,理论上需求开荒6个缓冲区。如果这样,每一个缓冲区的巨细显着不能确保到达实践通讯数据量的需求。结合FSK通讯特征,DTMF数据传输与FSK数据传输不可能同时发生,因而FSK与DTMF可共用相同缓冲区。相同串口接收与FSK发送、串口发送与FSK接收都不会同时发生,这样通讯只需求开荒两个缓冲区就可以确保模块正常通讯,考虑实践事务途径数据量情况,软件规划中为FSK接收开荒255字节缓冲区复用;FSK发送开荒45字节缓冲区复用。
4.1 CPU-5CE/16-85-2 FORCE主程序完结流程
图2 主程序流程
通讯模块主程序包括:CPU初始化、CMX865初始化、初始化建链、串口通讯和FSK通讯子程序等。主程序流程如图2所示。初始化建链环节是模块正常作业的基础,通过初始化建链操作,信息终端可以根据线路环境以及途径超时机制对通讯模块参数进行设置,确保通讯的稳定性。通讯主流程循环实行3个子功用函数:线路情况处理函数、串口数据解析与处理函数、链路坚持函数。线路情况处理函数规划了3种线路情况,即初始情况、空闲情况和摘机情况;正常作业时仅在空闲情况和摘机情况之间切换。其间在空闲情况检测振铃、根据情况位实行摘机、DTMF拨号等操作;在摘机情况根据情况位实行FSK收发、脱线检测、挂机控制等操作。串口数据解析与处理函数包括串口数据按指令集解析、对解析指令进行应对和情况置位处理部分。这样线路情况处理函数和串口数据解析与处理函数通过情况置位标志严密连接起来。FSK数据选用间断办法直接接收,接收完毕后在摘机情况下直接通过串口发送给信息终端。由于串口发送使用相对单一,为简略处理串口发送选用即时应对处理办法,涣散在通讯主流程各子功用函数中完结,提高了通讯功率。通过链路坚持函数判别串口通讯是否失常,通讯模块周期性地向信息终端发送链路坚持指令,如果3次重发均未收到终端应对指令,通讯模块将自动锁闭线路,重新实行初始化建链操作,完结串口失常的处理。
4.2 CPU-5CE/16-85-2 FORCE对外串口通讯协议
模块选用标准串口通讯,波特率为19 200 bps,10位异步办法。定义串口通讯数据包格式为:0x1E+指令+校验和反码(对指令的校验和反码),其间部分指令以变长办法发送。串口通讯指令有:模块初始化、链路坚持、DTMF接收/发送、FSK接收/发送、振铃、挂机等,指令具体格式和描绘此处不加胪陈。模块初始化上电后由通讯模块自动建议,直到正确接收到终端应对初始化指令后,通讯模块才建链成功。信息终端初始化应对指令供应FSK通讯模块参数配置信息。上电后如果FSK模块未收到终端初始化应对信息,则周期性地(每2 s)发送一次初始化建链指令,直到成功为止;模块FSK通讯过程中周期性地向终端发送链路坚持指令,如果未收到终端应对信息,则断开FSK链接重新开始模块初始化。
4.3 CPU-5CE/16-85-2 FORCE串口通讯完结
AVR单片机串口通讯往往选用SPI通讯办法[78],通讯模块串口通讯选用UART0控制/情况寄存器和数据寄存器完结。串口通讯子程序由串口发送/接收间断子程序、串口接收指令解析子程序和串口组包发送子程序3部分组成
