VSP5610: RGB control timing in VSP5640

Part Number: VSP5610

Hi team,

I have question about VSP5640. 

in each TR cycle, I know how to control LED statues, turn on or off, like below 

But for three TR cycle, how control RGB three LEDs?  how to switch LED in next TR cycle?

for example, at the first TR cycle, I configure R statues. At next cycle, I will configure G, what's the R statues and B statues?

thank you

  • additional question: if the T = (LEDn TG T15+1 ) * Tmclk > 1 line cycle , does the LEDn_TG have any output ? or the LEDn_TG cleared by the next LS?
  • Hi Betty, Kevin,

    I am not sure what you mean by TR cycle. I am assuming you are referring to the Line cycle time LS.

    Please refer to section 12.3 for the correct sequence to follow to enable the LED driver with the timing control.
    So if the timing registers are changed while activating the LED driver, the unintended timing may be executed during 1 line cycle.

    I guess if the LEDn_TG_T(15) > LINT, then LEDn_TG will not have any output. We have not characterized this case and so you may have to try it out. The LEDn_TG do not get cleared by the next LS.
