Pulse width modulation functions.

Function Documentation

void pwm_init

(

littleWire *

lwHandle)

Initialize the PWM module on the Little-Wire

Parameters

lwHandle

littleWire device pointer

Returns

(none)

Definition at line 217 of file littleWire.c.

void pwm_stop

(

littleWire *

lwHandle)

Stop the PWM module on the Little-Wire

Parameters

lwHandle

littleWire device pointer

Returns

(none)

Definition at line 222 of file littleWire.c.

void pwm_updateCompare	(	littleWire *	lwHandle,
		unsigned char	channelA,
		unsigned char	channelB
	)

Update the compare values of the PWM output pins. Resolution is 8 bit.

Parameters

lwHandle	littleWire device pointer
channelA	Compare value of PWMA pin
channelB	Compare value of PWMB pin

Returns

(none)

Definition at line 227 of file littleWire.c.

void pwm_updatePrescaler	(	littleWire *	lwHandle,
		unsigned int	value
	)

Update the prescaler of the PWM module. Adjust this value according to your need for speed in PWM output. Default is 1024. Lower prescale means higher frequency PWM output.

Parameters

lwHandle	littleWire device pointer
value	Presecaler value (1024, 256, 64, 8 or 1)

Returns

(none)
