PWM/IO Binding Register Select a binding register whose value serves as the duty cycle width percentage. For example, if the PWM frequency is set to 100Hz and the value of this register is set to 50. Then, this PWM outputs 100Hz pulse with 50% duty cycle. Users can use an input widget or Blockly function to change this binding register’s value, as a result, to change the duty cycle. Register Selector
Capute Mode When this pin operation is set to Input Capture. The caputre mode can be set to Rising Edge, Falling Edge or Both.
Count Register In Input Caputure mode, this register counts how many events of Capture Mode occurs since last time Count Register is read Register Selector
Elapsed Time(ms) In Input Caputre mode, this register holds the eplased time in ms since the last time the input capture mode related registers are read Register Selector
Binding Script In Input Capture mode, if a Callback Blockly fuction is enabled. Checkbox
Observed Behavior When the input capture mode is enabled and the binding script is enabled, whenever there is an input pulse and the pulse is counted, then this behavior callback function is called. At this time, the Count Register stores the number of pulses since last time it is read; whereas, the Eliapsed Time stores the duration in ms since last time this regisre is read. Once this callback function is called, both Count Register and Elasped Time are cleared. Blockly Editor

]]> Register Observer https://rdktech.org/rdk-documentation/widgets/system-widget-library/register-observer/ Mon, 18 Mar 2024 19:37:15 +0000 https://test-inc.xyz/?post_type=epkb_post_type_1&p=1208  

Register Observer is used to monitor any change of a selected register. Once the content of the monitored register changes, a Blockly callback funtion is activated.

For example, an ADC input is bound to a register and the result is displayed by a Circular Gauge widget. However, if users would like to use an LED widget to turn on when the ADC input value is larger than a predetermined value, then this Register Observer can be used. The Observer can monitor the value of the input ADC. Every time the binding register of the ADC changes, the callback function is activated to check the value. Once the value is larger than the predetermined value, the LED widget is turned on by the callback function.
