Hi Cristiano,
I've installed the DLC-247 and updated SimDash to version 1.3.6.
I also have your .56" three-digit 7-segment display. The problem is the display brightness is too dim. I have tried both methods, powering via USB and also via the 5-volt external supply with the switch on the DLC board toggled appropriately. The brightness slider in SimDash has no effect to the DLC-247. I've set the brightness to opposing extremes of 2% and 100%. There is no effect on the LED brightness. The brightness stays the same. Is the DLC-247 not recognizing the SimDash's brightness slider? (Please note, I also have the Pro Shift and I am getting lots of brightness from LEDs powered by the Pro Shift.)
Also, I have lots of surplus 7-segment displays. I experimented them with the DLC-247, but the LEDs are also dim. Is it due to the issue described in the paragraph above, or are these surplus LEDs the incorrect rating? They are 16mcd luminous intensity, 20mA forward current, and 4v forward voltage.
Thanks for your help.
