LP5030 problems

[ChrisT66]

Hello, I have assembled a LP5030 together with a ATMEGA328PB on a board. I tried to control a LED with the flowcode component LP5030. Unfortunately without success. Is there anything special to consider here?
The chip is enabled and initialized, the bus communication seems to work, but I can't get any LED to light up.

Does anyone here have a clue?

Thanks a lot, greetings Christian

Hello,

What version of Flowcode are you using and can you attach your program for us to look at.

Hi, I'm using version 9, can't upload the program right now because I'm on the road all day.
But is only a test program with the three commands INITIALISE, SETRGB and SETBRIGHTNESS. Address 0 and an array (ArrayLED[0]=100, ArrayLED[1]=100, ArrayLED[2]=100). For brightness 255.

Hi

I don't have the component but it simulates OK for me, however the brightness didn't appear to do much. That might be due to simulation.

I created an array for colour called RGB[3]

I initialised

Then I set brightness (which didn't seem to do much in simulation)

In a calculation I set each "colour" value

RGB[0]=255
RGB[1]=128
RGB[2]=255

I then SetRGB with Address = 0 and RGB = RGB

This illuminated the first LED to a kind of purple.

Compiled OK to Hex.

I assume you have checked clock settings, Channel, Baud etc and have pullup's if required?

If you are using v9 it would be better if you posted in the v9/v10 forum as you will probably get more help.

That's exactly how I did it. Then perhaps the IC does not seem to be correctly equipped. Thanks!
