New install, setup & connected to octiopi fine. Web page reads status fine, but the oled only displays Web Interface On You may connect to IP 192.168.1.209 Port 80

No status or weather.

Web page displays Time: 14:34:07 Host Name: octopi Status: Offline

Galashiels, GB light rain 1% Humidity 1.34 kph Wind Rain (light rain) 14°C

How do I get the oled to update?

Qrome commented 4 years ago

You might be having a hardware issue. If you connect and use the port monitor and you see that it is actively getting the weather and displaying all that stuff, then the wemos is running. It might be the display.

Make sure that you also compiled it with spiff 1M enabled.

It getting the weather data etc "country: GB temp: 14.61 humidity: 1 condition: Rain wind: 6.49 weatherId: 500 description: light rain icon: 10d

I have the flash size set to 4MB(FS:1M OTA:~1019KB) which I assume is the spiff setting as I can't see any other setting in the menu to change it.

The serial monitor is updating every few seconds but no changes on the oled I have tried with clock on and off and no difference to the display.

What pins are you using for the I2C on the display? If you are using D4 -- that is going to lock the display when the blue LED goes to flash. The wemos uses pin D4 for the internal LED.

Hairybiker commented 4 years ago

OK that might be it. I have it on sda/5 and scl/4 which is hardwired at the moment changing the led pin to D1 & recompiling

Qrome commented 4 years ago

Yeah, that would be it. This project flashes the internal blue LED as a status indicator. The moment it goes to flash the LED, it will freeze the OLED if you are trying to use D4.

By the way the Wemos D1 mini does not use D4 and D5 for i2c -- the default ones are D1 and D2 as can be seen in the pinout map. https://escapequotes.net/wp-content/uploads/2016/02/esp8266-wemos-d1-mini-pinout.png

This project uses by default D2 and D5 -- but you can use anything you want other than D4.

Hairybiker commented 4 years ago

D1 causes a hard reset every few sec. Trying D2 OK NO display at all now. Will rewire the display and try again

Qrome commented 4 years ago

Use D2 and D5 -- you should be fine. Sorry, this project defaults are D2 and D5. That will work for you.

OK That fixed it thanks for the help
