Hello, sorry for my English use Google translator. Which port you need to specify in ADDR? The address of my Lcd 1602 A i2c 0x3F, I tried to initialize the IDE, it works. ![lcd](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/d0354fd592f9846c8c8c720c5f517471183a8e0d.jpg) ---

You should enter decimal there. `0x3F` is a hexadecimal number equal to `63` when converted to base 10. Use 63. ---

Thanks for the reply. Yes I tried to enter a 63, while downloading it gives an error [object Object] ---

Sorry for the delay. I see the problem is in LiquidCrystal library but the message on the photo is truncated and I can’t tell what’s going on exactly. Would you expand the message (click the triangle) and copy/paste the error verbatim here? Also, what board model do you use? That’s important too. ---

Well, it seems like XOD distro has not set up correctly/completely and you’re missing the `LiquidCrystal_I2C` Arduino library which should be bundled along with XOD. I summon @brusher_ru to help 🧙 He could say which directory to look into and how to fix it. ---

Hello, @evil200006! Thanks for the report. I have reproduced this bug and it’s in cloud compilation service with the library for i2c LCD display. 😬 I’ve added the issue about it in the bug tracker and we’ll fix it soon. Until then, just compile projects on your machine if you’re using i2c LCD display. If it does not work for you for some reason, please report it and tell what OS you’re using. ---

Hi, I’m using Win7 64. I from the very beginning used Desktop IDE, please explain what you mean by compilation in the cloud? ---

It is an option you can check in the new window that pops up when you deploy, just above the debug checkbox, just above the Upload button at the bottom of the window. ---

As @gweimer said, this is an option in the upload pop up. This one: ![36](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/5959b16ce9790647eeb374ec76181a27dd6fdb0c.png) And the error that you posted looks like you checked this option. Try to compile your code without this option. It should help. ---

I deleted the win32-avr-tools file.tar.gz he was not downloaded completely. The next time you try to compile, a link error appeared in the console. I downloaded this file from this link and placed it where it was. And it worked. ![PumpXod](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/8a7b934e44e3077356977c07d1eb831c45282f4b.jpg)
