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...

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...

@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.

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...

@wwatson Really nice job and alot of testing to find the issue!!!! Nice that you got the three branches set up - at least for SPI probably keeps it cleaner. Still waiting for my lcd/camera shield to test with the SDRAM board - hopefully today...

The major problem with your code is that you are waiting 50milliseconds after your tone starts and then starting to read the ADC values, but you don't really know the phase relationship between your tone and the actual collection at the ADC. You...

Ciao Paul, both shapeshifter and microcosmos is on hold (not abandoned), we have other projects to carry on at the moment and we lack of developers at the moment.

Thanks! I ordered a power supply and the audio shield! I will post my code and draw up a schematic according to the guidelines this weekend. In terms of the audio splitting. Yes I was just thinking linear. I figured by splitting the song digital...

This sounds like a really awesome project. I want to help, but to give specific electronics troubleshooting advice requires seeing a lot more detail. Photos and schematics or clear diagrams are best. Small but complete test code also really...

There is a little more spread at the base of the odd harmonics, although the FFT sizes are also different. I had expected more of a difference, and I was wrong.

Code repository for V1 to save future y'all a bit of poking about.

So I left the minilab past Friday in a rush for a weekend trip, left the teensy in the breadboard with a wire connected from GND to GND rail on breadboard, and a loose PWM wire on pin 8 that was connected to a motor , no power being supplied...
