Hello all,
I am was building a reprap machine using arduino mega 2560 R3 with ramps 1.4
during engine calibration and checking endstops software restarted and I've noticed the attached LCD brightness was to full.
as I've tried troubleshooting I've only made things worse-
I think I've pressed load bootloader and had an error message.
1st the arduino gave device manager error codes and now it is completely unrecognized.
I tried loading FTDI drivers then realized its not related to this specific board and uninstalled.
I've noticed that when the reprap power supply is off and the electronics are connected only via usb the GUI on the LCD still functioning.
I've tried reloading bootloader using arduino UNO R3 as an arduino programme using this method:
and although it says it is succesful it is still bricked....
any idea if there is anything I can do to make this right?
edit:
just read this thread:
looks like same story... checked the LM1117 Voltage Regulator 5V regulator - pins 1 ~4.8V 2 grd 3 0V can this be the root cause?
hello all,
I got my usbasp and tried fixing my board...
this is what I did for the bootloader:

although everything seems to response ok board still isnt being recognized....
any idea why?
UPDATE:
I discovered that while trying to program the 16u2 usb communication chip I should've connected the 6 pin to the Mega 2560 R3 Aref 6 pin connection near the USB connection on the board....
when I tried connecting through there are repeating the experiment I got:
