GZ80Ⅱ单板加配 CMCP-16微打印机的思路,首先是检查微打印程序中调用其原单板监控子程序有那些?经查计有左移四位、十六进制转换 ASCII 码和打印程序的中断矢量地址079C。把它们和单板机的监控程序进行对比,修改配合打印程序。其次对打印程序的存储区分配重新定义,把原打印程序中的用户地址改到单板机的适当位置。最后写两块修改后的单板监控和打印程序,全部工作就完成了,单板机的使用功能仍保持不变。
GZ80 Ⅱ plus CMCP-16 micro-board micro-printer ideas, the first is to check the micro-printing process to call the original single-board monitoring subroutine that? Have been investigated by the left four, ASCII conversion ASCII and print the program interrupt Vector address 079C. Compare them with the single board computer monitoring program, modify the print program. Second, the redefinition of the allocation of the print program storage area, the original print program to change the user address to the appropriate location of the board machine. Finally write two modified veneer monitoring and printing procedures, all the work is completed, the use of single-board machine function remains unchanged.
