  1. Closed: Re: want to use Proteus make blocks missed parts why?

    Thanks.

    Watched the video, can you tell hot to modify attached drawing's mcp4261 section into sub-circuit?

    I want to make the small parts of circuit into blocks, but not work, say three buttons make as one block, the result is missed other two.

    1. no joystick for now, just multi meter test the V at p6 and p9, and the output is the result.
    2. currently ' testing the MCP461, use it if its good.

    Thanks, the info. attached.

    The funny thing is with these circuit and code, output at pot0 = 2.5 V, the output at pot1 vary: 0 - 5 V, whats wrong? tested few pieces all same.

    Ya,
    is it possible to use a Transistor kind?

    Closed: any solution to amplify the MCP4261 current

    Used a MCP4261 to generate a signal to control a analog joystick, seems its max current is too small, anyway can amplification it's signal?
    Thanks.

    Thank you.
    The attached is the circuit of the LM2596 Adjustable Converter, there is no datasheet, don't how to figure out the pot's signals.

    Thanks.
    The reason I want to have a reset function is the MCP becomes hot some time and the re powered make it works.
  14. Closed: Re: MCP4261 need manually power off from time to time or not working well

    Hardware or software. can this pin works as reset? say I switch it to 0, and then to Vcc ?

    Thanks,
    I mean the pin12 (SHDN), can this pin used by a switch or it just can be set by code?

    Any comment on how to use the reset pin?
  19. Closed: Re: MCP4261 need manually power off from time to time or not working well

    The CODE is here and the LEDS just on/off one time after added the shutdown function, otherwise it should be on/off cycle.

    Can you point out which pin is not correct? The drawing is what I'm using now and it is working well, just some time need be power off.

    Do you have idea why my MCP4261 need manually power off time by time, otherwise it can't be write correctly.

    Thank you wwfeldman and betwixt.
    Both P0W and P1W connected a 4.7k + LED for each, for testing only for now.

    The MCP uaed a 5V supply, and MEGA used USB power, both GNG together.
