Note: no promises on these boards, as I am a retired software guy.... I was laying out a complete board as a modified version of the earlier board I did for the Micromod. But decided to do a quick and dirty one that I can easily solder up. So...

Thanks, fixed it in v0.1.3

FFT on your graph shows bandwidth of 5Hz -> 80kHz. What is the bandwidth for your THD or THD+N measurement. Is it the same? I was looking SGTL5000 datasheet but they do not spec that for their measurement. They just say samplerate 48kHz. I could...

Check the connections, and there should be only two 120ohms resistors. One at each end of the bus Angelo

When I am connecting 2 can controllers with teensy board I am able to read and write data through can but when I am connecting can shield with Arduino and connecting to one of can controller then I am not able to read can messages which is...

There is an open source platform which includes a single-channel noise reduction algorithm (if this is what you are looking for). Maybe this is of help? There a links to the github rep and references. http://www.openmha.org/

Hi Paul I did try adding SPI.endTransaction() at the end of the loop but that also didn't work.

Good to hear that you already checked all these options. Good luck with the project! Looking forward to seeing progress and/or the final setup. These pneumanic cylinders sound impressive. I like such mechanical things.

Not sure if it matters but I'm missing SPI.endTransaction(); while using SPI.beginTransaction(SPISettings(20000000, MSBFIRST, SPI_MODE3));. Paul

Thanks, fixed it in v0.1.3

Hello everyone, I’m currently working on a part of a big project that requires me to read the converted digital signals from an ADC (ADS8354 - https://www.ti.com/lit/ds/symlink/ads8354.pdf ). I know the Teensy 4.1 has a 12-bit ADC feature but...

Real-world noise from the enviroment, kinda like the background noise reduction used in hearing aids. A lot of experience with signal processing for a student, but not so much about it on hardware (just had one lab and the different between that...

Thanks taj-ninny. The potentiometers were bought from a local store in Melbourne called Jaycar. The knobs on the end I acquired from my father along with lots of tools etc. when he died nearly 30 years ago. I don't know were he got them from, he...

Ahh yes! We did look into max4live but couldn't figure out the coding especially for 8 different audio signals going into their own FFT. Wasn't much info on how do to it from our understanding. For a previous iteration of this project we...

I agree that this sounds like a great project! Do I understand that right that there is a Laptop/PC with Ableton Live involved in the Setup? In this case it could be easier to do all the signal processing in software there and just send trigger...

@luni , I noticed an issue in your HiResClock library. In file T4xSource.h, function getTicks() returns tickType, which is uint64_t for T4. However, curVal, which is the variable meant to hold the 64-bit return return value, is defined as...

Would love to show this on the website. Any chance for a photo showing the hardware connection with MicroMod and with Teensy 4.1?

While @KurtE has been busy with CSI we also been playing with the OV5640 5MB camera which we got from Adrafruit: https://www.adafruit.com/product/5673 for the most part it was compatible with Flexio that we used for the OV2640 but of course lib...

Was this circuit board ever built? Do you have any photos, especially any photo or video of the LEDs in use?

Ich habe es einmal mit einem IS2-USB-Code versucht, es hat funktioniert und das Audiosignal auf das iPhone übertragen. Außerdem konnte ich das Audiosignal des iPhones über die Kopfhörerbuchse des Audioshield hören. Als ich dann einen Code mit...

Thought I would mention, I am currently playing with trying to add CSI support for this library, as the Teensy 4.1 has enough of the CSI pins exposed for 8-bit transfers, and the control signals. I am starting off with the OV7675 camera, and I...

Here's an example on how to do SPI masters on T4 with DMA. In a non blocking way. I also did a SPI DMA Slave library, but it looks like it's the master that you want here, and then three times in parallel, so SPI0, SPI1 and SPI2 hardware that is...

I don't know. There are several things that could cause problems. E.g. can your IPhone act as usb host? If yes, then I am still not sure if my code will work with an IPhone. I used my Windows 11 notebook for testing during the develpement and at...

I think it might have more to do with the ER-TFTM101-1 display as I am using the same length wires as well. I do not have any other displays to test with...

@ghijkmnop: The reference regarding the 3.3V restriction applies to the display data & clock signals ("Caution: Use only 3.3V signals with this display. CS, D/C, SDI, SCK, T_CLK, T_CS, T_DIN are NOT 5 volt tolerant.We recommend using this...

That helps a lot-- thank you very much. :)

Hello-- I have the Teensy 4.1, and the 3.2" TFT display, purchased here. The pin reference for this display says to use VIN for the VCC pin, but later on in the description it says that the display must be operated at 3.3V, and VIN is labeled as...

As some of you know I made a 4.5 (facelift) that adds USB-PD (USB Power Delivery up to 12V). And it also has SDCARD. Those are the only changes made (moved the boot button position as well), hence the word facelift. The USB Host port has sort of...

I converted my toy Dalek into a synth. Inside is a Teeny 4.1 and Audio Card. The antenna and arms are potentiometers and joysticks and I used the fasttouch library for the touch buttons on the Dalek. Here are the innards...

Update ER-TFTM1011-1 10.1" LCD is working on the T4.1, MicroMod and SDRAM Dev Board V4.0. All except MicroMod work with 8-bit and 16 bit bus configuration. The T4.1 is by far the most stable of all three. The SDRAM board and MicroMod are unstable...

Love your project ! Where did you find those long shaft potentiometers with cute joystick headers? cheers

An obvious change would be to connect the "PD" USB port to USB2_DN and USB2_DP on the IMXRT1062 so it can be properly used as a host port, rather than using both ports identically as either device or host. Although looking at the spacing of the...

Wow cool, that essentially gives SPI almost DMA speed but not messing with all the DMA thing Thanks for the tip :) , I don't know we could just attach interrupt with the spi.tranfer() function. Though I just completed the coding to use T4 DMASPI...

@wwatson echoing @mjs513 - great work getting the driver ported to the different boards! FlexIO is a bit confusing at first, but the 8080 stuff is fairly simple to setup and debug compared to other protocols. The place it gets messy and really...

Most of those pins are already there, iirc the only missing ones were some of the data pins around CSI 2 to 5.

Quick answer is yes. in one of the conversation posts I listed them as well: which is the same on your list.
