Hi, first of all, thanks for this tool. it looks very good and worked almost fine for me. I was looking for a way to display in my OLED screen when the raspberry boot and shutdown, so will be easily using a bash script. However, after I install your script and tested, it worked but does a conflict with the node red oled node. It looks that after I send the comand "/.oled s" it send the screen a comand that only allow to write to line 1 and this maybe is the cause of the conflict. Not sure, but i will like to use your script in conjunction with other libraries for the OLED. So i can maintan using node redd for capuring data and display it in the oled and also when I boot I want to use your script. Hope you cand give me some hints in how I can fix the issue. Im from Chile and looked into your web page. Lot of interesting projects that i will take a look. Thanks for publishing them. Attaches is a small video of what I get after I run your script and that node red is triyng to use the screen after yours.

Does this script work properly on the command line?

Hi, yes, it works fine in the command line. However, after I run this script, any call to the oled screen from the node red ONLY is displayed into the line number 1. In order to come back to normal, I need to reboot the raspberry pi and avoid to run your script. It looks that the screen is saving something that need to be cleared.

I have never used node red. I'm going to try node red. Do you have a sample code for node red to display ssd1306?

DanielBendersky commented 3 years ago

Hi, I just finish a course of Node red and now I am a fan (I recommend you take a look on it). It's very useful and simple.

Here is how to install the library's. Just install 2 libraries, the OLED and the DHT so you can monitor a temperature and show it in the oled.

Also I attached the flows I created,. so you can just import them into your node red. Everything will take you less than 10 minutes.

Example of my flow. Is attached so you can import it:

PS: A you tube that explain how to configure the OLED in node red. Very clear and useful. Is in Portuguese, but I understood it and I dont speak it. https://www.youtube.com/watch?v=Ep2ZUAyiN7g https://www.youtube.com/watch?v=Ep2ZUAyiN7g

Hi.

Also I attached the flows I created

Where is it?

DanielBendersky commented 3 years ago

The flows are the jason files. Just import the jason files into node red and they will apear as flows. It is that simple. Let me know if it works for you. If you want I can do a zoom call and show you. The only think is I dont speak Japanese. I know a few words I learned from Judo. My sport. So just let me know if you want to meet.
