Hello sir, Thank you very much . STP04cm05 based led on msp430f67641 working fine. It is working with red , green and blue led blink ok. I have some confusion for color combining the RGB and generating different color of combination of led light. I tried with sending the different combination of frame but it blink with only one color means not getting the parallel output. i send the 0x01 --> LED_OFF 0x02 --> LED_RED 0x04 --> LED_BLUE 0x08 --> LED_GREEN it is working fine with sending this byte. problem 1> it is blink when i send the 0x0E --> for RED + GREEN + BLUE = WHITE but it is not show white color , it shows only red. 2> brightness of the RED led is very low. once again thank you very much for your reply waiting for the solution of the above my problem...
