Rasperry pi HDMI

Hi a question I have a raspberry 3b+ I made a simple software using the HDMI, but I don't see anything specific on the display that I'm trying a 7" display.
Thank you

Hi

You will need to post your chart as without such we have no way of knowing what you have created. Also please provide details of your display and connections.

You probably also need to install drivers on the pi to allow it to communicate with the display, can you get anything on the display e.g. the pi desktop? That's probably a good starting point before you do anything using Flowcode.

Hi, the display is the standard raspberry one.
https://www.raspberrypi.com/documentati ... splay.html
this simple program uses
RASPBERRY PI HDMI
I attach a project that simply initializes the monitor and should print a text on the screen but it doesn't work both on the display and also by connecting a monitor to the external hdmi output.
the debug displays correctly but then it's not actually like that.
another question if you wanted to use the touch of the display?
Thank you very much

I am attaching the display datasheets

flowcode creates a file without extension using sudo nano opens the file but doesn't run it if I want to start it without flowcode how should I do it? Thank you

Hi

Are you running a desktop environment on your Pi or "headless"? Did you make the changes to config.txt as per the WSH-11100 document? Does that then make the display work on your Pi (without running any FC chart)?

I installed raspian and run the desktop environment, tonight I'll try to follow the flowcode instructions pdf exactly and then I'll inform you Thanks

I confirm that the raspberry pi HDMI does not work whether it uses the display or using the hdmi output
the program is simple
1 installed raspian
2 updates done
3 created simple program with flowcode
4 initialized display
5 string plots
When I load the program a putty starts correctly but I don't see anything on the monitor.
But does this HDMI work?
i have doubts.
I would expect what I see in debug then also see it on the monitor but this is not the case

Hello everyone, following this guide I practically solved if the desktop started does not work but only start from the terminal
