+*Description*
+
+ performs PWM operations on CCP1
+ The target must support this.
+
+
+
+
+
+*Notes*
+
+ this is a heavy refactoring of the original pwm_hardware.jal
+ Stef's lib
+
+
+
+*Dependencies*
+
+ * [JalapiPwmCommon pwm_common]

+== Global variables/contants ==
+
+ * *`var byte ccpr1l_shadow`*
+
+
+ * *`var byte ccp1con_shadow`*
+
+
+
+
+
+== Procedures ==
+
+ * *`procedure pwm1_set_dutycycle(byte in duty) is`*
+
+
-----------------------------------------------------------------------------
+ sets dutycyle in low resolution mode
+ the 2 LSbits take their value from ccp1con_shadow, by default 0
+ this means if duty1 = 0, there's no pwm, if duty1 = 255, you're closed
to
+ (but not at) the maximum pwm
+
-----------------------------------------------------------------------------
+
+
+ * *`procedure pwm1_off() is`*
+
+
+ * *`procedure pwm1_on() is`*
+
+
+ * *`procedure pwm1_set_dutycycle_highres(word in duty) is`*
+
+ Because duty cycle is coded on 10 bits, the given value can't greater
than 1024
+ If not active yet, calling this procedure will enable PWM
+
-----------------------------------------------------------------------------
+
+
+ * *`procedure pwm1_set_percent_dutycycle(byte in percent) is`*
+
+ This procedure set duty cycle using a percentage
+ According to what has been computed by pwm_set_frequency(),
+ it converts the duty percent to a value suitable for the
+ selected pwm frequency.
