Library: embeddedCreatorLib ( Dafulai Electronics) / RTC
Description
This block will output system clock including year/month/day/week.
Parameters
Please double click this block to open parameters dialog below:
Let us explain parameters.
| • | Set Clock initial Value from parameters when Power on — logical scalar. Usually RTC has dedicated small "Coin battery". When micro-controller power off, RTC can stall run by this small "coin battery". So you don't need to initialize RTC's "Year/Month/.../Sec" when micro-controller power on again. This parameter value "True" means that micro-controller will initialize RTC's "Year/Month/.../Sec" from parameters when micro-controller power on. "False" means that micro-controller will not initialize RTC's "Year/Month/.../Sec" when micro-controller power on. |
| • | Year — drop list from 2024 to 2055 . You just choose from drop list. This is initial year, When micro-controller power on or reset, it will take this year as initial value if parameter "Set Clock initial Value from parameters when Power on" is true. |
| • | Month — drop list from 1 to 12 . You just choose from drop list. This is initial month, When micro-controller power on or reset, it will take this month as initial value if parameter "Set Clock initial Value from parameters when Power on" is true. |
| • | Day — drop list from 1 to 31 or 30 or 29 or 28. You just choose from drop list. This is initial day, When micro-controller power on or reset, it will take this day as initial value if parameter "Set Clock initial Value from parameters when Power on" is true. |
| • | Week — drop list from "Sunday" To "Saturday". You just choose from drop list. This is initial week, When micro-controller power on or reset, it will take this value as initial week if parameter "Set Clock initial Value from parameters when Power on" is true. |
| • | Hour — drop list from 0 to 23. You just choose from drop list. This is initial hour, When micro-controller power on or reset, it will take this value as initial hour if parameter "Set Clock initial Value from parameters when Power on" is true. |
| • | Minutes — integer from 0 to 59. This is initial minutes, When micro-controller power on or reset, it will take this value as initial minute if parameter "Set Clock initial Value from parameters when Power on" is true. |
| • | Seconds — integer from 0 to 59. This is initial seconds, When micro-controller power on or reset, it will take this value as initial second if parameter "Set Clock initial Value from parameters when Power on" is true. |
| • | Sample time in sec (-1 for inherited): — Sample time for this block. It is the same meaning as general Simulink block . |
Notes: Please configure RTCC. All settings must be done in IDE GUI configuration (It is MCC for Microchip Micro-controller)
Ports
Input
| • | En — "logical" data type's scalar. True means "RTC" keeps running and updating output port "Yr/Mon/D/.../Sec" continuously. False means "RTC" stop updating output port "Yr/Mon/D/.../Sec" and set initial values to input port "Yr/Mon/D/.../Sec" if it is connected or set initial values to parameters "Year/Month/.../Seconds" if related input port is not connected. |
| • | Yr — "unsigned 16 bits of integer" data type's scalar. It denotes initial value of "Year". If input port "En" is false, "RTC" will take this initial value. |
| • | Mon — "unsigned 8 bits of integer" data type's scalar from 1 to 12. It denotes initial value of "Month". If input port "En" is false, "RTC" will take this initial value. |
| • | D — "unsigned 8 bits of integer" data type's scalar from 1 to 31. It denotes initial value of "Day". If input port "En" is false, "RTC" will take this initial value. |
| • | W — "unsigned 8 bits of integer" data type's scalar from 0 to 6. It denotes initial value of "Week" (0 is Sunday,1 is Monday) . If input port "En" is false, "RTC" will take this initial value. |
| • | Hr — "unsigned 8 bits of integer" data type's scalar from 0 to 59. It denotes initial value of "Hours". If input port "En" is false, "RTC" will take this initial value. |
| • | Min — "unsigned 8 bits of integer" data type's scalar from 0 to 59. It denotes initial value of "Minutes". If input port "En" is false, "RTC" will take this initial value. |
| • | Sec — "unsigned 8 bits of integer" data type's scalar from 0 to 59. It denotes initial value of "Seconds". If input port "En" is false, "RTC" will take this initial value. |
Outport
| • | Yr — "unsigned 16 bits of integer" data type's scalar. It denotes current value of "Year". If input port "En" is true. |
| • | Mon — "unsigned 8 bits of integer" data type's scalar. It denotes current value of "Month". If input port "En" is true. |
| • | D — "unsigned 8 bits of integer" data type's scalar. It denotes current value of "Day". If input port "En" is true. |
| • | W — "unsigned 8 bits of integer" data type's scalar. It denotes current value of "Week" (0 is Sunday,1 is Monday) . If input port "En" is true. |
| • | Hr — "unsigned 8 bits of integer" data type's scalar. It denotes current value of "Hours". If input port "En" is true. |
| • | Min — "unsigned 8 bits of integer" data type's scalar. It denotes current value of "Minutes". If input port "En" is true. |
| • | Sec — "unsigned 8 bits of integer" data type's scalar. It denotes current value of "Seconds". If input port "En" is true. |
