Hi guys, about adjusting LED brightness using PWM, I usually see design that input the PWM signal from the mcu to the OE of the LED driver like for example TPIC6C595 to control the LED brightness.
Now, if I'm not using the TPIC6C595 driver and I would like to connect directly the LED to the IO pins of the MCU and I have more than one LED. So how do I control using PWM? Can all the signal from the IO become PWM signal?
I've found a project website (**broken link removed**) which they connect directly many LEDs to the mcu but still using PWM to control. I'm wondering how do they do it? Is it all of the IO pins can produce PWM signal?
