I am using an Arduino Mega 2560 with the Seeed Studios TFT touch screen and am thinking of building a LED controller to control my 8 Mean well drivers.
The Touch screen screen uses most of the PWM outputs of the Arduino board for its databits, so I don't have those ports available to drive the PWM inputs for the Mean Well drivers. I like to use the Tft Touchscreen for UI, so I am looking for another way to extend the number of PWM outputs.
The TLC5940 seems a good candidate, but it is a constant current output and meant as a direct LED driver. I am wondering if it is possible and safe to use it as the PWM input for the Meanwell ELN-60-48P? Or is there another solution I can try?
