While that is a decent idea, I've already got the 9488 housed in my jog wheel and ready to go with the rest of the hardware But my issue here isn't free ports - the T4.1 that I have laying around solved that. It's mostly the async comms between...

Awesome work jmarsh! What about SDRAM at 227MHz for framebuffer, still to slow? It would be pretty wild to take this concept and make a board. With the USB to HDMI "thingy" built onto the board. And use USB Host instead so that the ordinary USB...

Progress: 800x600, 8-bit (256 color customizable palette of RGB24) @ 60Hz over HDMI.

@MichaelMeissner Spinal Tap was indeed my inspiration :)

I don't recall seeing the entire mockumentary, but I recall Drummers for the Spinal Tap band did not have a long life span: And at the moment, of the 4 Beatles, only Ringo Starr has 2025 performance dates available (though Paul McCartney will...

To simplify and put into context - EEPROM.put on the T4 will do the same as .update for you, so use EEPROM.put. If the user constantly saves their settings every hour, 24 hours a day, 7 days a week, it will take them almost 12 years to do 100,000...

Creating a new thread with exact same question won’t give you a concrete answer either 😆

@Math51: You're still missing the two additions that @beermat spelled out at the bottom of his post. I can attest to the fact that, if you make these two additional changes to your sketch (in addition to attaching the required battery), the T4.1...

Without code, hard to correctly diagnose but...here's some stuff to think about: Teensy Loader will initialize the RTC clock when you program the Teensy and maintain power. If you power it down and up again, without a battery maintaining the...

The driver library and Windows / MacOS client software have been updated to support streaming buffers over USBSerial1. Just need a bare Teensy 4.x and a USB cable!

I don't want to dissuade you, but I may be working on something more "modern" than VGA...

I've had good results transferring data at rates over 10MB/second using the USB Serial port. I've recently found that it makes things simpler to use the USB Dual Serial setup. I use SerialUSB1 for the data transfers and Serial to control the...

Which 2 pins would you want to give up to be able to have this?

I realize what you need, I forgot they named the support documentation this way, too. This document helped when I was figuring out some stuff for the NT35510 a few years ago....I'll PM you a link to the NT35510 Application Notes PDF I have...

Is that a specific file you are looking for? Or are you making up a name to match NXP style documentation, where they present a full working solution, source code included, for the NT35510 in an "Application Note"?

If you have a Teensy with Ethernet and a TFT screen that you update with buffers of 16 bit RGB565 pixel data you should be able to use this code, along with the supplied Mac or Windows client, to also display (and control) the screen remotely on...

Hi there, Here is my latest project that I wanted to share : the minichord! For the full documentation of this fully open source project, first the Github (https://github.com/BenjaminPoilve/minichord/tree/main), then the website...

I was (and am) surprised by the I/O speed and the overall snappiness of it. I haven't benchmarked the raw SD card access speed, but even when writing a single large file to the filesystem (read: with the filesystem layer making things slower) I'm...

Waiting......we introducing something new ....give me 5...

Future Teensy with will USB-C. I can't discuss any other details at this time. I probably should not even write this message, but hopefully it at least answers this 1 simple question.

This is wonderful news. I really hope it's the 1170. Great work Paul! Dear santa, make the next Teensy also have SDRAM and MIPI. 😁

Hello dear DIY friends.. I'm working on a new project called Degenerator 2. It's a polyphonic sampler and synthesizer based on Teensy 4.1 with 16MB sample ram and touchscreen. In 2011 I started developing my first monophonic sampler/synthesizer...

Hi Paul, I am working on a private Teensy project (controlling my model rail way, German forum post here) where I sometimes exceed the Teensy 4.1 RAM1 or flash limits (especially with the debug build). To avoid this, I disable some FNET configs...

Do you feel like giving the QNEthernet library a try? It should be just about a drop-in replacement. You can selectively disable all the features.

I'm not sure there are any, unless you're already familiar with it. This is more of an exercise in futility than anything else - though I have to admit that it does perform way better than I expected.

Thanks! I found it but unfortunately it's still too vague as to how to communicate with this chipset. Real bummer as it has a very small footprint, and seems to have strong capabilities.

Interesting thread. That Murata chip indeed is very small. It would be pretty epic if a library for the Teensy was made in order to use it. The Portenta H7, GIGA R1 and some other high end Arduinos does use this chip. So I'd say it must be pretty...

I can help. But first, which version of Teensyduino are you using? May I suggest updating to 1.59? That should fix the problem.

I released v0.30.1 about two weeks ago. Here's the Changelog: ## [0.30.1] ### Fixed * Fixed wait-for-close for non-altcp connections. Link: https://github.com/ssilverman/QNEthernet/releases/tag/v0.30.1

Revisiting the original problem 4+ years later... Looking at code from a different project, something very obvious occurred to me: why not bitbang the PSRAM instead of using FlexSPI? I took the code from earlier posts and modified it: #include...

IT WORKS!!! The CCM_CS1CDR was the last caveat!! 😁

MAADS (MIDI Auatomated Acoustic Drumming System) is a controller and set of actuators that use MIDI to play real drums. This hobby project was developed using the Teensy LC and later controllers implemented the teensy bootloader with the ARM...

Looks like this post above was 18,000 for @defragster !!!! - this 18,001

Tested in practice in this project. Small add on board to use the 4bit SDIO directly on the Teensy4.0 at the cost of the usb host pads, Kicad 8 project including gerbers. https://github.com/hexeguitar/Teensy40_SDIO_adapter

Time to satisfy your retro cravings! I revisited this old project recently and did some well needed updates. It is a polysynth based on (real) commodore SID's. It accepts up to four of them and supports both 8580 and 6581 variants. Control is...

I have ubuntu 24.04 installed now. and MTP appears to somewhat work. I was able to download this jpeg file and then open it... But it did not want to show the image if I double clicked on it in the MTP window. Or maybe I did not wait long...

The PlatformIO inspect function does the analysis on a compiled ELF file, compiled in debug mode (to get extra info to generate the report). Obviously, the linker cannot generate the ELF if section sizes are too large for the regions. So, it's...

QNEthernet supports TLS via lwIP’s “altcp” scheme. There’s instructions in the Readme on how to wire this up. It’s a little complex at the moment, but there’s an Mbed TLS example, MbedTLSDemo. See...

It's been a while since I configured NativeEthernet, but I think the default socket size for NativeEthernet is 2048, which seems suspiciously close to your limitation. NativeEthernet.h You could increase that to some bigger value before...
