Note:
This only uses MAT 1

Function Documentation

void CT16B1_deinit ( uint8_t  state )

Stop PWM.

Parameters:
[in]statePWM output state when pwm disabled

Definition at line 84 of file CT16B1_PWM.cpp.

uint16_t CT16B1_get_period ( void   )

Return period.

Definition at line 119 of file CT16B1_PWM.cpp.

void CT16B1_initpwm ( uint16_t  period_arg,
uint16_t  defaultstate,
uint16_t  prescaler_arg 
)

Initializes PWM.

Parameters:
[in]period_usPeriod in us, when prescaler is 48
[in]defaultstateState after initializing
[in]prescalerDivider from AHBCLK
Note:
Prescaler 48 gives 1 us timer ticks
Run Start() to start pwm

Definition at line 33 of file CT16B1_PWM.cpp.

uint32_t CT16B1_isStarted ( void   )

Return 1 if timer is started.

Definition at line 126 of file CT16B1_PWM.cpp.

void CT16B1_reinitpwm ( void   )

Re-Initializes PWM.

Definition at line 69 of file CT16B1_PWM.cpp.

void CT16B1_reload_mat ( void   )

Reload all match compare registers.

Definition at line 95 of file CT16B1_PWM.cpp.

void CT16B1_set ( uint8_t  matnr,
uint16_t  value 
)

Set channel PWM.

Definition at line 103 of file CT16B1_PWM.cpp.

void CT16B1_start ( void   )

Start PWM.

Definition at line 76 of file CT16B1_PWM.cpp.

void CT16B1_wait_refresh ( void   )

Wait for timer to reach 0.

Definition at line 111 of file CT16B1_PWM.cpp.
