clock/timer/MCU

Hello everybody.

I asked question about timer in timer and clock forum, but TI employee Noel Fung told me to search for answer on this forum. Here is his answer: 

Hi Andy,

Sounds like you need a MCU, suggest you make a post in our microcontroller forum. Our clock and timer portfolio do not have the product you are looking for.

Here is my question:

I have a task to create/buy a simple timer:

it has to have 8 channels for 8 different loads and timer for engaging load or opposite

example: 1LED is powered for 15mins, after that stops but 2LED begins to light for 10mins and so on. Concrete time - is just for example. The best way to have something to set the time for each load

Can somebody help me to understand - whether such working module exists or not?

Thanks!

  • Hi Andy,

         I think what Noel Fung is suggesting that you look into TI microcontrollers which can do what your application does. 

         There are lots of TI microcontrollers these are MSP430, Tiva, Hercules, Concerto and so on. These microcontrollers are designed for specific applications from low power to high reliability.

         I recommend looking into MSP430 and Tiva ARM microcontrollers.

         What you can do is ask at MSP430 and Tiva forum.

    Edited  . . . 

         This post was moved from "Other Microcontrollers" forum to "MSP430 forum".

  • Thanks a lot!

    May be one could help me here. May be there is a working module or a scheme at least.......

  • Once you have a CPU that you can program, and some sort of timekeeping method, you can implement every pattern you want. And you can change it without changing your hardware by just changing the firmware.
    So if you use an MSP, all you need is some sufficiently precise timebase. Either the internal REFO of the 5x family (~1%), or an external watch crystal (few ppm).
    Then your code can simply count the time (seconds or milliseconds or whatever) and do actions based on the count.
    The dedicated clock and timer chips covered by the other forum you tried first, are mainly for short-distance precision timings (delays) or clock signal generation and distribution for complex electronics (like PC mainboards)

     For the outlined task, even the smallest MSP will be powerful enough. Take a look at the G2 LaunchPad, it contains a sufficiently powerful CPU, a board with breakout connectors and an integrated JTAG programmer for only a few $.

  • Dear Michael,

    thanks for response. 

    My problem is that I can not write a program (((

    That is why Im searching for ready-to-use product or something similar

    You need DMX stage lighting system then. This is just an example, there are many DMX controllers and dimmers covering wide price/feature range
