6.7 GPIO Functions

GPIO functions control up to 56 GPIO ports provided by Eddy-CPU, 34 GPIO ports provided by Eddy-S4M
They can spot 3.3V power or control writes with individual GPIO port.
Pins provided by Eddy CPU/S4M are public pins that can be used to control other devices and are not used solely
for GPIO.
Eddy CPU/S4M provides 32 signal lines as 3 port groups; Port A, B, C.
Each port in Port A, B, C can be configured to be used as device or GPIO. They can be configured in Web.
Please refer to sample source ‘

testdk.c

’ in Eddy_Apps folder for precise usage.
