Technical specification NeoTrellis RGB Driver PCB Supply voltage: from 3.3 V / 5 V

Does the trace look any different if you arrange your code like this SPI.beginTransaction(SPISettings(2000000, MSBFIRST, SPI_MODE1)); digitalWrite(slaveSelectPin, LOW); // take the SS pin low to select the chip: stat = SPI.transfer(0x00)...

We use good BOURNS type PEC11L Series encoders. They have 100,000 cycles. The manufacturer recommends an external RC filter (see data sheet). The RC filter already has a pullup. Therefore internal pullup resistance is not necessary.

I've tested various configurations and haven't seen anything resembling 8 cycles.

1us/div means you're sampling at 1MHz, half the specified SPI clock rate of 2MHz...

Hey guys, I'm trying to use a teensy 4.0 for a SPI project. #include <Arduino.h> #include <SPI.h> // include the SPI library: const int slaveSelectPin = 10; void setup() { // set the slaveSelectPin as an output: pinMode (slaveSelectPin...

Using the instructions here (thanks @shawn) , I installed 1.59B4. All my projects compiled cleanly. Linux 6.6.3, pio 6.1.11.

thanks,I will have a try

Win 11 - Ctrl+P command didn't work? JSON string was right - closed IDE 2.1.1 and reopened and saw 0.59.4. It installed in under 30 seconds to update from 59.3 Had a sketch open and i built fine and uploaded to a locked T_4.1

Assuming the request processing doesn't take too long, you shouldn't need many sockets. I'd start with the default and see how the project behaves. What you describe is the client-side. I'm curious which server you're running on the Teensy?

Overall, I think you have a good chance of completing this project. You have the necessary technical skills and experience and are clearly passionate about this project. Here are some potential problems you may encounter: Hardware Limitations...

Neotrellis needs +5v for Vin. Onboard I2C level shifter is set for 3.3v by default.

Photos of the hardware are what's missing here. The problem is almost certainly poor soldering or a wiring mistake or misunderstanding. I can confirm 64GB cards definitely do work with the audio shield and Teensy 4.0. We can help you get the...

I have written c++ code that reads from 4 x tf-minis: https://sourceforge.net/projects/benewake-tfmini/

Alcon As I mentioned in the other thread on the LSM6DS I received mine yesterday and decided to take it for a spin with the beta4 and worked no issues. refernce...

Just a quick update. I received my Adafruit LSM6DSO32 yesterday and just had a chance to test it out. Unfortunately they are out of stock of the X version. Using their LSM6DS library and hooking it up per: works no issue: Adafruit LSM6DSO32...

Hello, I have the same issue here. Here is my setup: * Teensy 4.0 * Audio Shield * SD Card inserted (PNY 64G) Not able to run the listfiles Getting these error messages on the serial monitor This is my code What am I missing? Thank you...

Sorry, I misremembered- this was the post https://forum.pjrc.com/threads/28037-Teensy-3-1-and-K20-FlexTimer-config-for-FreqMeasure but apparently I was doing frequency, not pulse width.

To get 16 bits of color over flexio you’ll need to use FlexIO3 on a Teensy 4.1 Downside is it does not support DMA. Or, go custom teensy routes and break out all FlexIO2 pins which are also the eLCDIF pins (I have don this - 24bit color over...

One way I can think of doing this with the least amount of hassle would be to choose one pin for "sync" on a pin group different than the other four and to set the priority lower than the pins on a different port, or set different port IRQ as a...

It is a web page using js and Ajax. The web value of the components (Ajax) are refreshed every 1000mS. The web page should be able to contain at least about 20 components. And be viewable from multiple computers and mobile devices simultaneously...

There's a whole bunch of considerations. I'm curious, which server are you running?

Is it possible to retrieve and display the usage of ram1 and ram2 in the Serial Monitor? In order to determine the optimal number of sockets. Thanks.

That mixing of signed/unsigned should be triggering a compiler warning - wonder if there are lots of other warnings?

The easiest way, if you're using the Arduino IDE, is to change the LWIP_NUM_TCP_PCB value in the lwipopts.h file. For PlatformIO users, and for those Arduino IDE users that know how to change command-line flags, you can also set this macro value...

TTL is simply in the product name, but is not relevant to the question. @Rezo is correct in his reference to one example product. Looking for good existing libraries that might embed a FlexIO implementation under a common graphics library, or a...

I 'm trouble-shooting an issue with writing to SD using SdFat, and I noticed the code below in SdioCard::begin(SdioConfig sdioConfig). A signed int is used, which I think can cause CARD_ERROR_ACMD41 to be incorrectly returned, depending on the...

I ordered 3954 and 1611 from Adafruit.

After you install any of these libraries, click File > Examples and scroll down the long list to look for your freshly installed library's examples. Some of these libraries give multiple ways to access the hardware. You want "hardware SPI"...

You can find libraries in Arduino IDE, like this:

But what has TTL got to do with it? This is just a 16/18 bit parallel interface as far as I can figure out.

Hi everyone! I am creating a custom PCB and incorporating a significant chunk of the Teensy 4.1 layout. I came across some beta stage routing diagrams for all the layers at some point, but am unable to find the page again. Can anyone paste a...

If you search “GitHub mcp23s17 teensy”, you will find some libraries. Here is one. https://github.com/tonton81/MCP23S17

I had got one mcp23s17,but it hard for me to drive it using SPI on teensy 4.0,can anyone give me some examples? thanks very much!

Installed on W11 machine. Did a couple quick compiles, MMOD tft viewer with ILI9341_t3n is working

Hi all, yes it's been a little bit. So I guess I lost my Teensy 4's, lol, so I'l order a 4 and 4.1 soon.

Just installed on win 11 home edition with 2.2.2-nightly-20231021, path for package: https://www.pjrc.com/teensy/package_teensy_index.json. Installation went smoothly and quickly. Tool teensy:teensy-compile@11.3.1 already installed Tool...

Here is a fourth beta test for Teensyduino 1.59. Arduino 2.0.x, all systems platforms: use Boards Manager to install Teensy version 0.59.4 (to refresh versions, Shift-Ctrl-P and click "Arduino: Update Package Index") Arduino 1.8.x, Linux 32...

yes thats what im using, connected to the JST socket and teensy 3v for its power the samples im using in the sketch, and some build images are here: https://www.dropbox.com/scl/fo/jwpgmfc1oixp94589pzdw/h?rlkey=hbdkrdd6wt8n1l64de2l8yko1&dl=0

Thank you MarkT for the reply. :-) I found the Examples yesterday. :-)

Hello all, I am using "QNEthernet" for the Teensy 4.1 and have a web server running on it with Ajax and JS. Now there seems to be a maximum of 8 sockets set, in which header file can you adjust this and what would be the maximum fetch bare...

Hello Luis. I’m currently using 11 outputs on a board I made for 14 outputs.. I’m not sure if I chose that number because of a hardware limit but I’m pretty sure 14 will work. I only use 300 leds per strip however for what it’s worth I just...

For the PCB, Adafruit Product ID 3954, and the Silicone elastomer 4x4 button keypad Product ID 1611. A couple of strategically placed elastic bands can be used to to strap the two parts together for experimentation. If you want to play with 8x8...

Since it's relevant, I wanted to reference the post I just made in another thread about Teensy4.1,OctoWS28,Artnet+FastLED using the above-mentioned libraries and blog posts... I'm hoping my consolidated repo helps a few people here :) The...

Using Teensy 4.1, OctoWS28 and the Ethernet connector, I could do 24 universes at a good quality. I throttled the Art-net server and FastLED Teensy node down to 30fps, which worked well for my project. There seems to be a bunch of discussions...

If I were to order parts to try reproducing this problem, which specific items from Adafruit do I need to buy?

I tried running older IDE versions. Looks like ZST works all the way back to IDE 2.0.4, at least on Linux. Assuming Windows and MacOS are the same. Looks like IDE 2.0.3 is the point where we lose compatibility with "extracting archive: Not a...
