I haven’t seen the code, but I’m guessing Arduventure uses an early version (not published in this forum) of my code to remove the USB stack. In it, I light the RGB LED in magenta (red + blue) before testing for the UP button during boot, to enter the bootloader for upload. I was hoping the LED would stay lit once the bootloader was entered but it’s immediately cleared when the pins are reset.
Since the LED turned out to not be of much value, and used code space, I decided not to use it in the Arduboy2 v5 library release. (I also changed from testing the UP button to the DOWN button, to be more compatible with @Mr.Blinky’s Cathy bootloader, and not conflict with flashlight mode.)
Yes … I can’t see how its really related, but I have noticed a flash of blue when I start the Arduboy. I have never noticed it before and (jumping to conclusions) I have assumed its related to the new library.
Thanks Scott I was hoping it was software related, the lower brightness is actually IMO nicer (although a little short) than the normal boot LED and would make a nice alternative and good compromise for those that prefer to skip the logo & LED’s.
The brightness isn’t lower but the duration is shorter. The only way to lower the brightness is to control the LEDs in PWM analog mode. I don’t want to do that with the boot logo because it would take quite a bit more code than the current digital control.
