Re: ST7789 display

Another brain-teaser (for me at least). I need to display an arrow-like element in the shape of a triangle. Like for a down-pointing arrow I'd have a small triangle with a horizontal base and two slanted down-oriented sides, see attached. Not a big issue, but I want to be able to fill such an arrow ...

Re: ST7789 display

OK, I think I can do that. How do I then access such a bitmap for printing in FC?

Edit: there's a bunch of bitmap drawer functions in the gLCD lib. Back to the drawing board!

Re: ST7789 display

Hi Martin, yes that could be an option, I really only need the + and - signs and 0 tom 9 digits to read an attenuation value from a few meters away. Something along the lines as the attached; that's not a very high resolution display but lookes quite professional. But maybe there exists a utility th...

Re: ST7789 display

Can I tag onto this thread as my issue is similar. When I want to increase the font size to improve distant reading, I only see a FontEnlarger icon (ST7789 display). That makes the resulting number larger but extremely blocky, see attached. Surely there must be an intelligent way to increase the fon...

Re: Architecture advice please?

Making good progres, despite being short on time. Setting up the access point from the ESP Wroom works OK. Need to educate myself on the protocolls to open the connection to other stations and get the logon process figured out. After a lot of debillitation I selected a graphic color display to go wi...

Re: Architecture advice please?

Hi Leigh, yes I did that exactly. The only deviation was that the instructions tell you to select ' v4.1 (release version)' of the EDF-IDF while version 'v4.1.4 (release version)' was the only 4.1 available. There was also a choice 'release /v4.1 (release branch)' , no idea what that is, I just igno...

Re: Architecture advice please?

OK, I did follow Ben's procedure, the first batch of commands failed due to:

C:\Users\jandi\Desktop\esp-idf-5\tools>python tools/idf_tools.py uninstall
python: can't open file 'tools/idf_tools.py': [Errno 2] No such file or directory

Re: Architecture advice please?

Hi Jan, ESP IDF version 5 cannot be used (with Flowcode). This is causing the problems. The build is not successful. Please read Martin's link carefully :) OK, but that sends me to a procedure by Ben that he himself calls "you may break things" and that appears only to get me back to EDF 4.1. So I ...
