i found your blog via the OLED Library which is used in ESPEasy.
Thanks so much for your cool work!

At the Moment i have just one Question:
Is it possible that your web based font generator (http://oleddisplay.squix.ch/) is down at the moment?
I get an 404 if i follow this link…

kind regards

First of all, thanks a lot for sharing your code, is really great!!!
I’ve been playing with the weather station kit for a couple of weeks. Currently I’m trying to display stock market information. Something like a stock market ticker. I want to display the values for different stocks in the same frame but at different times. Let me explain. I want to know the last price for the stock Apple and Netflix. Therefore I get the info from makitondemand and store it in an array. I added an additional frame (lets call it frame5). The first time frame5 is drawn I want to display the last price of Apple that is the first element in the array. The second time frame5 is drawn I want to display the last price of Netflix, that is the second element in the array. The third time frame5 is drawn I want to display again the first element of the array and so on…
Is there a way to do that?

Regards,
Marcos

You can invert the hole display, but that’s probably not what you want. In the end the xbm format is just pixels, if I remember correctly so in theory you could just invert all the bytes and get the inverted image. Inverting can be done by XORing every byte with 0xff… But no satisfaction guaranteed;-)

Hi Sean. This worked for me in the past. I had the two displays running on different pins, since their I2C address is kind of hard coded. It reduced the performance a little but was still OK. You’ll have to instantiate to display objects. Let me know if it worked out!
