求翻译：1. 修改应用测试程序：应用测试程序判断DI采集是否跳变，若发生翻转则使一普通DO输出，平台固件从向应用发送DI跳变数据到收到DO输出命令计时，计算出应用逻辑运算时间，使用示波器的两个通道测量DI跳变到DO输出总的时间，将两时间相减计算出系统反应时间；是什么意思？

(1) Modify the application testing procedures: application of test procedures to determine whether transition di acquisition, if the flip is to make an ordinary do the output, the platform firmware do output command received from the transition data to the application to send di timing, to calculate

1.Modify Application Testing Program: application of the test is whether or not judgment DI acquisition transitions, if it is to flip out, a plain DO platform firmware applications to send from jumping DI DO output received data to the command, the calculated time application of the logical operator

1. modify application test program: application test program judgment DI collection whether jump variable, if occurs flip is makes a general DO output, platform firmware from to application sent DI jump variable data to received DO output command timing, calculation out application logic operation t
