    3D Printer Monitor Wemos D1 Mini ESP8266

    Hi Qrome,Got it working, I thought I'd post the fix here in case it helps someone else. Thanks again for pointing me in the right direction. I watched Chris' video on here, and he was using the 2.4.1 board manager. I also noticed that his was WemOS D1 R2 Mini. Also, in re-reading your instructions, you said to Select Board: "WeMos D1 R2 & mini"Mine just said WemOS D1 R1 nothing else. Strange, it worked enough like this for the board to program, but not to fire up the OLED. I removed all versions of the ESP8266 board management software and just installed 2.4.1. Once I did that, WemOS R1 D2 & Mini were a choice under board manager. I selected that, reflashed it and it's working great! Thanks again. Jeff

    Hi Qrome,Thank you very much for the reply! I'm still beating my head against the wall. I checked and the ESP8266 board version was 2.4.2 so I upgraded to 2.5. I'm new to this so I'm not 100% sure what each library is doing, or if there can be version conflicts. Below is what I show installed on my board manager and Library manager. I recompiled and uploaded this morning after upgrading the OLED module to v 4.0.0 and the board manager to 2.5.0. I also verified that I have just over 4 volts to the pins vcc and ground on the OLED. I get no backlit or anything though on either of the OLEDs (tried two different ones) I tried. Not sure if that's normal. Thanks again so much for any thoughts. This is the first project of this type that I have hit such a wall on. I'm sure it's something simple...

    3D Printer Monitor Wemos D1 Mini ESP8266

    Hi Qrome, I am having trouble making my display work as well. I can get to the printer monitor web page and all is working there. I verified 2 times that my pins are connected correctly. I also tried a different WemOS board and then another OLED display. I then found your comment here and tried version 3.2.6 and 3.2.7. I get an error compiling (pasted error below). Version 4.0.0 compiles fine, no errors. Hoping maybe I'll get lucky and you have a miracle for me? Thanks in advance for any thoughts or suggestions -JeffCompile Error:invalid conversion from 'const uint8_t* {aka const unsigned char*}' to 'const char*' [-fpermissive]

    Made two of these. One for the top of my printer to display time and Octoprint % done. The other for a clock and weather at my bench. Thank you!

    LED Marquee Scroller Wemos D1 Mini ESP8266

    Hello, Thank you for this, I love it. I have two going one just as a clock and the other to monitor my printer, the humidity and the job. Is there a way I can adjust how long it sits at the clock though? I'd love to have it just sit at the clock for 1 to 3 seconds only then scroll again. Thanks in advance for any assist. -Jeff
