Pray god to help write a design with VHDL language digital clock procedures, as far as possible don't module, show only the minutes and seconds, on the integration of four digital tube display,
CodePudding user response:
Your SCM? Is there a peripheral clock? How the clock I/O definition, digital tube and how do I/O defined? Pure write their own system or a ready-made system?
CodePudding user response:
This problem should not be in VB version ask you

reference 1st floor still human response: your SCM? Is there a peripheral clock? How the clock I/O definition, digital tube and how do I/O defined? Pure write their own system or a ready-made system? System can be ready, don't buttons, write a program, directly on the digital tube display four zero, then automatically start, need 50 hz frequency division as a Hertz, CodePudding user response:

It involves you a few questions and steps: 1, what is your MCU, MCU are built-in clock, if their own clock, the clock battery part of the plugin can ensure normal operation of the clock, 2, if the MCU is not bring the clock, so what are you using the external clock chip or module, because different chip or module communication acquisition is completely different, like DS12C887 DS1302 and DS12C887 is built-in rechargeable batteries, theoretically with a electric power can be empty cases run 10 years and there is no built-in battery DS1302, can dry battery or lithium battery or plugin farad capacitor as the electric power supply, so the program also consider whether you need charging and charging voltage, protocols and timing of gathering information, of course, work is different also, collect the information content is different also, So this kind of thing is the absence of certain hardware program can not sure how to write, CodePudding user response:
refer to the eighth floor still human response: you it involves several issues and steps: 1, what is your MCU, MCU are built-in clock, if their own clock, the clock battery part of the plugin can ensure normal operation of the clock, 2, if the MCU is not bring the clock, so what are you using the external clock chip or module, because different chip or module communication acquisition is completely different, like DS12C887 DS1302 and DS12C887 is built-in rechargeable batteries, theoretically with a electric power can be empty cases run 10 years and there is no built-in battery DS1302, can dry battery or lithium battery or plugin farad capacitor as the electric power supply, so the program also consider whether you need charging and charging voltage, protocols and timing of gathering information, of course, work is different also, collect the information content is different also, So this kind of thing is the absence of certain hardware program can not sure how to write, I was using a development board, the kind of plugged into the computer, install the driver, the program written, run directly, CodePudding user response:
That also have to make clear what is MCU, PCB schematic diagram and wiring method of the MCU use what the peripheral circuit
