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.
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...
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...
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...
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...
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...

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...

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...
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.

You have B1_12 and B1_15 available for pixclk and mclk.
I would recommend using the pins shared with FlexIO2 wherever possible (for example hsync and vsync are on B1_14 and B1_13), since that's better at handling variable-length (compressed)...
Yes you are right that B1_12-15 are already on the board.
We should probably make a new version of the excel document which has all of these pins on it...
As for mixing CSI and FlexIO. Not sure how... Probably need to read those sections in...
My main question would be, what do you even need the Teensy/Arduino pin numbers for when writing code for modules like CSI and FlexIO? You can use IOMUXC_SW_MUX_CTL_PAD_GPIO_x and IOMUXC_SW_PAD_CTL_PAD_GPIO_x to initialize them (which works...
@KurtE can we get an original excel copy of this so that we can edit it?
https://github.com/KurtE/TeensyDocuments/blob/master/Teensy4%20MicroMod%20Pins.pdf
If you are building a specific board for a specific purpose, I say have at it! IF you like hard coding it like:
IOMUXC_SW_MUX_CTL_PAD_GPIO_AD_B1_13 = 0x4U;
IOMUXC_CSI_DATA04_SELECT_INPUT = 0;
IOMUXC_SW_PAD_CTL_PAD_GPIO_AD_B1_13 = 0x0U,
go for...
Note: that is simply a print to pdf of one of the pages in the excel document:
https://github.com/KurtE/TeensyDocuments/blob/master/Teensy4x%20Pins.xlsx
Note: @mjs513 did a modified version of this that I think is in @defragster github project...
