Started beta coding (0.1.07 beta)  on support for scanning Wire and Wire1 if supported e.g. DUE.

If some other functionality is missing, please let me know. I might add it :)

do you have links to the RAMPS1.4 - LCD datasheets?
what is a ReprapsDiscount Smart controller?
how are these connected?

the I2C pins for a MEGA are different than on an UNO (did you use the right ones?)

For I2C you also need GND connected, and 4K7 pull up resistors are needed.

How do you power the device?


It looks like your PC uses an Arabic font? is that possible?
The red board at right is "ReprapsDiscount Smart controller"

I did not do any pin or use any data sheets because all the boards are pre-installed !


The board uses the usb power and an externall adaptor for stepmotors !

It is not "Arabic", It is "Farsi"

MrMirza

I found the problem, The baud rate in port scanner was wrong !

now the problem is "0 devices found in 346 milliseconds"

anw tnx for yr attention and yr codes !

You are right, sorry

I'm not familiar with it

It seems that VDD pin power is 4.3v , is it the reason that no lcd is found by scanner codes even lcd's ledes turn on ?
