I would probably use the Teensy's 5V output (at the Vin pin) instead of the 3.3Volt output (4 ohm speakers could be a lot of power at 3.3V). Did you set the jumpers for gain correctly? Here is what the information page says: Five...

Thanks Kurt Ed

Kurt & Mike: I am sorry to bring this old forum thread back to life, but I have been having difficulties with text sizes ever since I started using the RA8876 instead of the RA8875. Here is the dilemma, in order to determine where to place...

I have made changes to the copy files from SD to Flash code to close any open files for all the error return points as you have suggested, (I think this could have been written a little more elegantly as you so apply have described it), however...

I'll have to check that out! Thanks, Ed

H4yn: I have attached to this post similar code that uses FrankB's Wave Player code which is kind-of old but it does work just fine using QSPI_Flash. If you have a moment check it out, as it is not very complicated. Regards, Ed

I am using the Teensy4.1. The version of Teensyduino that is currently be used by PlatformIO is 1.59. Here are the two files Tick and Tock

h4yn0nnym0u5e: Actually this is remarkably similar to mine in the way it works, first initialize the SD card, then initialize the LittleFS Ram (in my case LittleFSFlash), then copy the file from the SD to the LittleFS file. In my case there are...

Just for example on my Mac: Xcode.app uses: 23.41GB Wireshark uses: 232.1 MB WhatsApp uses: 328 MB VMware Fusion uses: 1.26GB Visual Studio Code.app uses: 567.5MB Visual Studio.app: uses: 1.63GB No Platform IO is not very big compared to a...

How about this compressed file of just the Main.cpp, I am sure you can figure out the rest. About the IDE, I also have used many different IDE systems over the past 5 decades, and you are correct many of them had steep learning curves. I have...

@h4yn0nnym0u5e: I created a bare bones project to try using your Audio system to play from QSPI Flash Memory using LittleFS, and it does not work. My code tells me that it is playing, but nothing is coming out of the audio system which is...

DrM: Aaaw the good old days at Hughes Santa Barbara Research Center. This design brings me back to the great times that I had designing and working with CCD arrays (IR) forty years ago. Keep up the good work! Regards, Ed

Kurt et All: The resistor combination you are seeing on that pin is what we in the hardware world call a "digital active termination". Why Sparkfun has done this is anybody's guess. As you have already surmised that pin will only be usable with...

h4yn0nnym0u5e: I have read this entire thread and have not found a solution for playing directly from the LittleFS file system. I also looked in your examples and did not find any examples of using the LittleFS instead of a SD card. Could you...

Sammy: I think you may mean you are looking for Mil Spec 883 level B, which is the chip spec. common requested for all Military type activities. After over 30 years in the Aerospace World I found that most Aerospace companies used 883 Level B...

David: You cannot use MTP with the Mac Finder as this is a MicroSoft protocol that has not been implemented on the Mac. However there are several apps you can download that will read this protocol, google is your friend. Regards, Ed
