VM_DCL_PWM_CONTROL

Syntax

typedef enum {
  VM_PWM_CMD_START = 0xD06,
  VM_PWM_CMD_STOP = 0xD07,
  VM_PWM_CMD_SET_LEVEL = 0xD0C,
  VM_PWM_CMD_CONFIG = 0xD14,
  VM_PWM_CMD_SET_CLOCK = 0xD1B,
  VM_PWM_CMD_SET_COUNTER_AND_THRESHOLD = 0xD1C
} VM_DCL_PWM_CONTROL_COMMAND;

Description

This enum defines the control commands for PWM module. The vm_dcl_control() uses these commands to control different functions of the PWM device. The applications should use the DCL (Driver Common Layer) APIs to control PWM.

Example

  #include "vmdcl.h"
  VM_DCL_HANDLE pwm_handle;                      // Declares a VM_DCL_HANDLE variable.
  VM_PWM_LEVEL_T pwm_level_var;
  pwm_handle = vm_dcl_open(VM_DCL_PWM_KPLED, 0); // Calls vm_dcl_open() to get a handle. The second parameter is always 0.
  pwm_level_var.pwm_level = 2;
  vm_dcl_control(pwm_handle, VM_PWM_CMD_SET_LEVEL, (void *)(&pwm_level_var)); //  Calls vm_dcl_control() to set the KPLED full brightness.
  vm_dcl_close(pwm_handle); // Calls vm_dcl_close() to close the device.

Members

Members	Description
VM_PWM_CMD_START = 0xD06	Starts HW PWM control.
VM_PWM_CMD_STOP = 0xD07	Stops HW PWM control.
VM_PWM_CMD_SET_LEVEL = 0xD0C	Controls VM_DCL_PWM_KPLED. The keypad LED only supports 3 levels: 0,1,2. 0 means stop PWM; 1 means 50% of brightness, 2 means 100% of brightness.
VM_PWM_CMD_CONFIG = 0xD14	Configures HW PWM.
VM_PWM_CMD_SET_CLOCK = 0xD1B	Sets PWM clock.
VM_PWM_CMD_SET_COUNTER_AND_THRESHOLD = 0xD1C	Sets PWM counter and threshold.
