（2）Defauted IO order number for the test program is 85、86，other IO order numbers can be selected if needed,so need a short connection of corresponding pins before test.
（3）Purpose of test program is to test input&output function of pins corresponding with IO order numbers 85、86.
（4）Take the output of 85 as the input of 86.
（5）Take the output of 86 as the input of 85.
Test method
（1）Click icon“GPIO”，to start test program.
（2）Click“out”on left side of black line，then click“0”，finally click“Confirm”.
（3）Click“In”on right side of black line，then click“Confirm”；then value outputed on left is 0 shown behid “In”.
（4）Change value outputed on left,remove check “0”，select“1”，finally click“Confirm”，then an according change also happen behind In on the right,e.g showing up“1”。represent output in 85 and input in 86 are normal。as below：
