Hello guys. I want to controll my apa102 led strip with the de2-115, but I never used VHDL and I cant even turn on the First LED. I hope someone can help me, I just need to See A simple Code just for turning on the First LED.

Then try that apa102 thing and when you have specific problems. Simulate those three tings before going on hardware! > I just need to See A simple Code just for turning on the First LED. According to page 3 of that datasheet it is not more than a few lines of code: https://cdn.sparkfun.com/datasheets/Components/LED/APA102C.pdf > and I cant even turn on the First LED. So simply define a constant vector with value x"00000000ff00ff00ffffffff" and shift that out left bit first while generating a clock of around 500kHz... BTW und OT: wenn du aus Deutschland kommst, dann kannst du ohne Weiteres im deutschen Forum posten. Englische Threads kommen aber ins englische Forum.
