MicroCore Labs The MCL68+ is a Motorola 68000 drop-in replacement emulator. It uses the Teensy 4.1

Because that speed is only achievable in UHS-I mode, which requires external circuitry to switch the SD signal voltage from 3.3V to 1.8V. Otherwise only high speed mode is supported, which runs at 50MHz - with 4 bits of data per clock that's a...

It does not matter what @whitebengal meant or not. I suggest that any thread on Adafruit vs Sparkfun (and this one) is closed immediately. If there is a need to enter into a Teensy development due to non PJRC events, than this should be named...

Ok, closing this thread.

Hey all! Here's a quick project I made, and kind of a PSA for those that don't know. You can use the Teensy's USB Host connection to convert USB devices (keyboards, game controllers, mice, etc.) into MIDI controllers. It works on both Teensy...

Since I am an oldie going to give an old saying:

Yup, still using win7 on one machine myself. My DAW setup would be a complete pita to reconfigure, with no guarantee that all the VST and VSTi would still work, or my older version of Cubase, without needing to also "upgrade", with either...

In the other thread, Coremark was brought up again. Lady Ada seems to have expanded it for the RP2350 so that it takes both cores into account. I have further expanded the code and it now also runs with freeRTOS – i.e., “real” preemptive...

I sent you (PM)

I wish I could tell you all the details but it's been a while since I was working on that project (about 3 years). From what I remember all SAI 1~3 is running in slave mode and it's not synced to S/PDIF this is one of the reasons I am interested...

Bugfix update pushed: intermittent S/PDIF tends to cause weird PLL speeds (nothing to lock to), which in turn was resulting in an attempt to transmit NULL audio block pointers. This isn't trapped by the Audio library, and the Teensy crashes...

Well that's not good I didn't have any issue yet with the CD spdif output project. By the way I am using SAI3 for AudioOutputADAT3 8ch Output instead (MQS) Medium Quality Sound on pin 31_TX_DATA _ [C3] _GPIO_EMC_36.

OK, after a lot of distractions, I've done a bit of work on this and have a work-in-progress branch for consideration, if anyone's interested. As it turns out the fallback to the built-in clock doesn't appear to work as expected if the S/PDIF...

Hi, Sorry, I am answering quite late as I was busy with work but I finally got some time to try out your PR. I cannot really tell if it changes anything, as it is not noticeable in practice when using the robot. I guess that is to be expected...

Between 2020 and 2022, I added this page about Teensy compatibility to the unofficial Teensy wiki project: https://github.com/TeensyUser/doc/wiki/Teensy-Compatibility I also created this google spreadsheet on various microprocessor layouts...

Yes, that was my conclusion, too. Strange, because the datasheet appears to imply S/PDIF transmit will use the internal clock if the receive loses lock, without needing software reconfiguration. I'll get to it at some point, lots of family stuff...

Been too busy but I just managed in fixing the CD frequency. I was wrong on the frequency I use the wrong cd service manual :mad: New Crystal: 4981-QT49-16.9344MBBK-B-ND Interesting I think we need some software SAI reconfiguration depending...

Hi everyone, I’d like to share a failure case I ran into, in the hope it helps someone else. About a week ago I received my new Teensy 4.1 (ordered from Antratek, model TEENSY41-NE-PINS). I’ve been experimenting with it since then and was very...

I've come back to this to see if I can make things work as expected. So far, I've failed miserably :mad: I've adapted the code from post #45 slightly (you have to do the pinMode() call first, then the Alt-mode to output the S/PDIF clock). I'm...
