i am currently using the NCP5623 (I2C LED Driver) to light up my 5V 1A (as written on the box) RGB LED strip.
i followed the sample connection as shown on the datasheet of the NCP5623 and when i ran my code, only a faint red glow can be seen (i was trying to run a full white light). confused, i took out the cable that is connected to the red pwm, and my led strip became green. again, when i took out the green pwm cable, the led turned blue. yet when i place the red pwm cable back in, the led strip became faint red again.
my led strip is a 4 cable led strip, i doubt it is of a good brand but it is what my school provided me with. for the RGB cables (the first 3) i connected them to the I2C just as the datasheet shows. as for the last wire, i connected it to power which is running from the 5v pin of the reaspberry pi.
i read up and it says that the faint glow could be due to not enough power supply? but i thought it should be sufficient as the box says 5V 1A and the website says 5W. any help will be appreciated.
