Using the amazing Pi-Blaster daemon I managed to control a connected RGB strip (to be exact: this particular one http://www.ledstripkoning.nl/led-strips-rgb/losse-ledstrips-rgb/5-meter-150-leds-rgb-led-strip/ and here in more detail). The LED is driven by a 24V power supply and connected through MOSFET's. However, I'm experiencing a rather annoying problem: when setting any value (0,2 or 1 for example), the led is not giving a constant result. To illustrate, please see this small video: https://youtu.be/qEt5gFcJue4
I've also tried using the default PWM (hard and software), which also results in (random) flickering.
Any thoughts on causes and possible solutions are highly appreciated; it's driving me nuts for days now.
