Display Board evaluation help

 

¿ªÔÆÌåÓý

I have a couple of the 3.3V ONLY display boards prebuilt and I want a couple of volunteers to test them out.? They have to be: 1) people with working radios, and 2) have displays that misbehave (meaning if you move them around, elongate the cable, etc¡­ the processor locks up).

?

I don¡¯t really have the problem so its hard for me to fully evaluate if the display driver boards completely solve this issue.

Re: V12 compiling error

 

For reason I can't explain, the IDE hides some libraries in the folder you defined in your Preferences section, which you can find at the File-->Preferences menu:

Inline image

As you can see, my projects go the C:\BookT41Rel4\Software. In that folder, you will find a subfolder named Libraries. The timer.h file is found there. If you have not defined a project folder in Preferences, I'm not sure where the file is placed and you will likely get the file not found error message.

Where are my libraries located?

 

All:

This has also been discussed on this site. By default, the Teensy libraries are installed in the directories located at the following path:

C:/Users/Econjack/AppData/Local/Arduino15/packages/teensy/hardware/avr/1.59.0/libraries

This directory will be different on your system (might be User). The packages directory on my system has folders for arduino, builtin, esp32, rp2040, and STMicroelectronics along with the Teensy folder. If you use a Teensy-only library, using backets:

#include <thislibrary.lh>

will search the Teensy path as shown above. If you use a standard library (e.g., like the UNIX System V library (e.g., string.h), using brackets searches the arduino search path. If you use double quotes:

#include "SDT.h"

the compiler looks in the project directory for the file. If it still can't find the file, it will search the arduino path as a last resort. If that fails, you get the "cannot find file" error message.

Installing a New Library

In the arduino IDE, the left side of the IDE has an icon that looks like several books on a shelf. This is the library manager. You simply type in the name of the library you want to install and the manager will try to find and install it. However...

If the library doesn't appear in the list, go to the Sketch-->Include Library-->Add .Zip Library and locate/install the missing library file.

Please send the compile stats on the code I sent you. Make sure you set the compile options using the Tools menu mentioned earlier before you compile the code .

Re: V12 compiling error

 

Again, any time you get this type of message it's because you haven't installed the library. I have pointed out many times that the URL for any non-standard library (i.e., not part of the normal install procedure) that we use will have its URL in the SDT.h header file:

#include <Chrono.h> ? ? ? ? ? ? ? ?// https://github.com/SofaPirate/Chrono/
#include <LinearRegression.h> ? ? ?// https://github.com/cubiwan/Regressino/
#include <Linear2DRegression.hpp> ?// https://github.com/nkaaf/Arduino-Regression

Go to the listed URL, download the file, and install it. Al and I have tried to get others to adopt this convention, but have not been completely successful. That said, everyone should check the T41 header files for a URL if their compile issue a "No such file" message.

Re: V12 compiling error

 

Well, that didn't go well. This was done to see what happens to the stack space on Tim's system. (I even looked his email up on QRZ so I could just send it to him. Obviously, the addresses are the same.) Anyway, Al, Oliver, and I are testing this release and are close to having everything working. We will have a "real" release soon.

Re: V12 compiling error

 

That's not enough, and probably causes a stack crash at some point. To fix, go to the Tools menu and select the "Option: Smallest code with LTO" and try again. That should increase the stack space by a factor of 10x. I also selected the 528MHz option for the CPU speed. Others suggest this option extend the life of the Teensy, but I don't know that for a fact. I cannot see that it affects the performance at all.

T41 Calibration Routines

 

Hi Everyone,
I am in the process of completing a major revision of the T41Calibration routines. I am on the last one - SSBPA cal. I hate to quote a time to release - these things have a mind of their own. If I can't get it done by the end of today, I will release an incomplete version as a beta.
Thanks,
Al
