2.4 GPIO Test
This test aim at the following 16 channel GPIO Definition:
J16[GPIO1_4
、
GPIO1_7
、
GPIO1_8
、
GPIO1_9
、
GPIO7_11
、
GPIO7_12
、
GPIO7_13
、
GPIO4_5]
J31[GPIO4_24
、
GPIO4_26
、
GPIO4_28
、
GPIO4_30
、
GPIO5_5
、
GPIO5_7
、
GPIO5_9
、
GPIO5_11]
Test Principle:
[Gpio_test 0] test the situation when gpio do not have external
connection, set all pin to low level, then set them to high level, through
external measure [gpio] actual level to confirm whether gpio is normal or
not.
[Gpio_test 1] will read external level signal directly, user can
compare read level data and connected level data to confirm whether
[gpio] is normal or not.
