Hi All,
I see " Ramp LED" description, I think that means let LED turn on / off gradually, not directly, right?
It need more PIO and hardware support, can we did it directly by software ?
Best regards, Boki.
That would be my guess.
Sure, with any old microcontroller you can just pulse-width modulate the pin driving the LED can thereby dim it. I did this at a company I once worked for that made identification card readers and had a translucent bezel around the card's slot; the LEDs were bi-colored and this was supposed to encourage people to insert their cards.
Unfortunately it turned out that another company had a patent (!) on dimming LEDs like this... apparently this was in response to the patent the company I worked for... which was for the equally absurd practice of using bi-color LEDs (and I think for using a translucent bezel too). Sheesh.
