GPIO operation

[!Note]

1. If you purchased SV50PB module or SV50PC module, you need to enable it in Module Configuration GPIO function, and then re-upgrade the system, it can be used normally.

Operation function

Definition of the name of each platform operable pin

• Z11S platform

  Currently the platform only retains 3 groups of io ports for operation.

  // 3 groups of io port definitions
  #define GPIO_PIN_B_02        "B_02"
  #define GPIO_PIN_B_03        "B_03"
  #define GPIO_PIN_E_20        "E_20"
  
  #include "utils/GpioHelper.h"
  
  // read B02 io port status
  GpioHelper::input(GPIO_PIN_B_02);
  
  // B02 io port outputs high level
  GpioHelper::output(GPIO_PIN_B_02, 1);
  

• SV50PB module

  The following 12 groups of io ports can be operated:

  // SV50PB
  #define SV50PB_PIN7         "PIN7"
  #define SV50PB_PIN8         "PIN8"
  #define SV50PB_PIN9         "PIN9"
  #define SV50PB_PIN10        "PIN10"

  #define SV50PB_PIN26        "PIN26"
  #define SV50PB_PIN27        "PIN27"
  
  #include "utils/GpioHelper.h"
  
  // ead PIN7 io port status
  GpioHelper::input(SV50PB_PIN7);
  
  // PIN7 io port outputs high level
  GpioHelper::output(SV50PB_PIN7, 1);
  

• SV50PC module

  The following 25 groups of io ports can be operated:

  // SV50PC
  #define SV50PC_PIN2         "PIN2"

  #define SV50PC_PIN30        "PIN30"
  #define SV50PC_PIN31        "PIN31"
  
  #include "utils/GpioHelper.h"
  
  // read PIN7 io port status
  GpioHelper::input(SV50PC_PIN7);
  
  // PIN7 io port outputs high level
  GpioHelper::output(SV50PC_PIN7, 1);
  

• 86 boxes

  The following 4 groups of io ports can be operated:

  // 86 Box
  #define Z6X86BOX_PIN7         "PIN7"    // corresponds to IO1 on the hardware
  #define Z6X86BOX_PIN8         "PIN8"    // IO2
  #define Z6X86BOX_PIN9         "PIN9"    // IO3
  #define Z6X86BOX_PIN10        "PIN10"    // IO4
  
  #include "utils/GpioHelper.h"
  
  // read PIN7 io port status
  GpioHelper::input(Z6X86BOX_PIN7);
  
  // PIN7 io port outputs high level
  GpioHelper::output(Z6X86BOX_PIN7, 1);
