Screen gets messed up after a while #154

Hello,

I followed the instructions and it works for a while. Not sure why but screen gets messed up after a while and from what I could notice it gets messed up after a pause to get the time/weather data. Problem is that it randomly starts doing it, sometimes it works ok for a couple of hours and sometimes it does it much sooner. On the image I uploaded it seems like screen is upside down but while it worked it is in proper orientation. Only thing I did to the code is enter the needed data (API keys and such) in Settings.h prior to upload but I noticed the same behavior if I upload the code with no changes. SSD1306 on Wemos D1 mini. Hardware seems to be ok as it works normally for a while but with no experience in programming I cannot say it is the code. Not sure what is happening here :(

Never ever seen this. Please check all the wires are cleanly connected and not shorting. I have a feeling it is an issue with the connection to the OLED.

I've checked and they look ok (with multimeter). Screen end is connected with jumper cables and wires on the Wemos end are soldered. Also if there is a short it wouldn't work ok for a while then go berserk? When I plug it in it works just fine. I found that it doesn't get messed up during the pause for time and weather data collection but happens randomly. Anyways I borrowed another Wemos from a friend since all of mine are not available and re-did everything but using the same screen. Looks ok so far, it's been on for ~30 mins. If it stays that way then there's definitely something wrong with the first Wemos. I'll post an update in a day or two after it has been turned on the whole time.

Looks like I found a culprit, the screen! I used another Wemos but with the same screen and it started acting again. Only reason why I tried with the same screen was because it used to work fine on my Raspberry Pi so I didn't suspect it can be the cause. Using the white SSD1306 now and it has been turned on w/o any issues for over 5 hours now. I don't have another blue/yellow OLED so I can't tell is that the issue but it shouldn't make a difference. I will be using a blue one in the future. Thank you for your time and thank you for such a cool and practical project!

Awesome! Glad you got it all worked out.
