Error uploading

[Dutchy-79]

Hi,

I'm trying to get this to work and bought a Wemos and LCD, I eventually changed the adres because at the back it says 0x78

First few attempts didn't gave an error though nothing on the screen so changed the adres. Selected board is LOLIN WEMOS D1 R2 & mini on COM 3

Now it says this.

Arduino: 1.8.6 (Windows 10), Board: "LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Disabled, 4M (no SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 921600"

Sketch uses 482068 bytes (46%) of program storage space. Maximum is 1044464 bytes. Global variables use 47972 bytes (58%) of dynamic memory, leaving 33948 bytes for local variables. Maximum is 81920 bytes.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Device manager says USB SERIAL CH340 COM3 so that should be okay.

Any idea?

To make sure I didn't create the error I downloaded a fresh copy and tried once more. Done Uploading though no image and no Wi-Fi network available.

Okay I kept trying and now I have Wi-Fi setup and still no image. I have 3 different displays 2 say 0x78 on the back and 1 says nothing. I tried keeping it stock and also changed it to 0x78 and no image with them.

To get it to work I had to install a previous version of the board ESP8266 version 2.4.1 works for the board.

[Dutchy-79]

one more step, just soldered SCL to D1 and it works. last issue is the weather saying N/A

[Dutchy-79]

After 2 hours struggling everything works. Please add you need ESP8266 2.4.1 and pin D1 for SCL if there is no image. weather now works too.

I will update the readme to I dicate you must use ESP8266 core 2.4.1 or higher. I am using 2.5.0 just fine. Most everything else is covered in the raedme file.

Probably because I used one of the cheapest clones from AliExpress 🤣

Just mentioned it because I didn't want people to say you did a bad job while it's caused by the library and board versions.
