Guarug:
Another Mac user here, to find any folder of file for that matter you can simply use the Go menu in the Finder:
Go/Go to Folder
and then type in the path name into the window that opens, it does not matter if...
Kurt:
What does an F5 do on Windows? I have not used Windows for a long time.
So, you are saying that I should use the "MTP.send_DeviceResetEvent()" after I close the file and then when I open it again and change...
Jeglin:
OK, I understand as I have been teaching electronics to mostly graduate engineers for over 40 years. It seems that going to a university for an education, for a long time (more than 40 years) is only about...
Jeglin:
Most of the DAC's you will find mentioned here on the forum are used specifically for audio work, and since the human ear is not a linear device a lot hardware design is built in to these products to compensate...
Kurt:
Here is the way my Teensy4.1 software works:
It logs environmental data from a BME680 at 10 second intervals for 24 hrs to a RAMDisk with the the current date in it's name.
At midnight it closes the...
Wwatson:
Ahhh yes, I barely remember back in 1967-68 in High School when I wrote my first simple program with punch cards on teletype connected to the off site IBM mainframe downtown. 1970 I had to write my programs...
Watson:
Thanks for your trouble and advice.
I have rewritten the parts concerning the subdirectory, instead of trying to open a subdirectory (which cannot be done because it always fails) I found the part in the...
WMXZ:
I forgot to mention that the app I am using on the Mac is called: MacDroid.
I also was using another app called MTP for Mac but, it is in beta test and stops working after 10 days without informing you, so if...
WMXZ:
So are you saying that after I write a new file on the SD Card, or change the file name on the RAMDisk, I should use a MTP.addobjectEvent(); command to the MTP library?
If that is correct I will try it and see...
Hi, All you MTP experts:
I have created a project that saves about 600K of Sensor data into a RAMdisk file on the Teensy4.1.
Every day at Midnight it moves the file to the SD Card, renames the RAMdisk file with the...
Paul & et all:
This program is originally 6580 lines of code, however I have trimmed it down to the bare basics, and still sort of doing the same thing as the original program.
It is supposed to create/initialize a...
Defragster:
After taking care of the Root issue, I now have another issue.
I can successfully create a subdirectory called "EnvironmentalData" with no problem, it even shows up on my Mac using MTP.
How ever I seem to...
OatGrain:
I checked in my .platformio folder for teensy versions 1.56, 1.57 and 1.58beta and they all have the same version of the Audio Library (1.3).
It looks like the Audio library has not been changed in quite...
OatGrain:
Do remember that Visual Micro is only for Windows, so if you use another system it will not work.
I have been using PlatformIO now for a long time, since embedXcode on MacOS died and have been very happy...
Now I have another problem with LittleFS, it creates the FS but I cannot get it to create a root directory.
I ran the ExtRam test from Pauls Web page and it passed all tests.
Attached is the test program that is a...
I am hoping one you C gurus can help me with this issue:
When trying to open a new file for write in LittleFS it seems to want a const char for a file name. However I would like to append the date for each new file I...
goalJJB:
As defraster and Paul have both commented, What system are you using, Mac, Windows, or Linux?
Since I also use PlatformIO on my Mac (OS Monterey 12.6.3) perhaps I could help?
Please show us your...
Schlank:
Please post the output of the build with the errors. Also please post your platform.ini file so we can see if you have configured PlatformIO correctly.
When you post these items please include them between...
Uija:
I agree.
In the 60+ years of designing, coding, and using various computer's I have used a lot of different environments. In the 80's working at Hughes Aircraft we had insanely (these systems cost more than a...
BriComp:
I already said I have been using Visual Studio since EmbedXcode died.
I have searched the add-on section for Visual Micro Arduino and it does not exist on my recently upgraded Visual Studio.
I guess it is...
BriComp:
This happened a couple of months ago, someone on this forum (It might have been you) provided a link to Visual Micro and I decided to try it out. (I have been using Visual Studio with PIO since EmbedXcode...
Jimmie:
Why not use a small laser and a sensor at the other end?
or,
You could try two thin strips of aluminum foil very close to each other on a non conductive layer perhaps made of Capton or something like it. You...
BriComp:
A while back I decided to try your suggestion on my Mac(OS Monterey 12.6.3). It would not even install, I got a whole lot of errors with no explanation as to what the errors meant.
