Nah, with all the talk of version 2, very easy to do.

Nah, with all the talk of version 2, very easy to do.

Hi folks, It's been awhile since I've had time to do much development and I could use a sanity check on some choices I'm making. I'm working on a project where I need to read in 3 channels of PWM, do some processing, then output 3 channels of...

No matter how hard I search, I can't find teensy4.0's pcb design file. Do you know where I can download the file? Or can I get the file if you have it?

If you're still looking, there's a hex file in the Firmware directory in their Github repo: rolfdegen/Jeannie-Open-source-Synthesizer

Do note that the pins used for the serial ports are different between the Teensy 3.2 and Teensy 4.x. On the Teensy 3.2, Serial2 was on pins 9 (RX2) and 10 (TX2). On the Teensy 4.x, Serial2 is on pins 7 (RX2) and 8 (TX2). On both Teensies, only...

Right, that's the problem -- calling sendAfterTouch with 3 arguments does completely different things depending on if you're using usb or serial MIDI. If you're already aware of that, it's possible to work around, but it's a very easy mistake to...

Yes, please. It's entirely obnoxious and I hate it. GCC should learn to shut up. I don't care that something or other changed in GCC 7.1 when we are *SEVERAL* versions ahead of that. Don't care at all. I really do wish the Teensy default compile...

I realize this is an old thread, but I just dug out some Teensies that were sitting idle. Most of them tested fine, but 2 Teensy 4.0 did not. They are not detected when trying to flash via Teensyduino. I'm now using Windows 11, Arduino 2.3.2...

Excellent, thank you Paul

I have no way to test these suggestions, but at least the suggested changes below allows compilation without error . . . maybe this will help you to get started: Change the following in your sketch above: #include <FlexCAN.h> #include...

hello I used code just like this in the past on the 3.2 now moving to a 4.0 and changing some things for new screen but wont upload and gives me errors, could anyone help fix this? I'm not much a coding person. i think it has something to do...

My guess is the sin() function. Its input is in radian units, so ideally you should be giving it numbers between 0 to 6.28 (or whatever Pi * 2 is). But after your program has run for only 4 seconds, even for the first LED (i == 0) the numbers...

I was right - I was being thoroughly dense. Thank you for your patience!

Just scroll down to Arduino 1.8.x Software Development on this page, then select your operating system. The Teensyduino for .Arduino 1.8.x will download. Once you have installed your Arduino 1.8.x (and I find that you have to execute it just...

The .html file takes me to an IDE 2.0 scenario. The .json file is not it, is it? I'm still puzzled.

Diecast boxes are pretty much standard for the stompbox builds. AK4552 vs AK4452 - of course that was typo, i mean the 32bit 4452. The volume pot will fit, tested many times in practice, the 3d model is not the type i'm going to use, i've just...

Hi, I am a new student trying to figure out how to make a code that sends out simple can fd messages to a single teensy 4.1 microcontroller. I need help with a sample code that can do this as the example codes I run. come back with many...

In post #1 of this thread you will find download links for TeensyDuino installers. You just run the installer and follow the prompts.

This differs from the Arduino MIDI library, which overloads the function name (and thus, can't be extended to allow an optional cable number) https://fortyseveneffects.github.io/arduino_midi_library/a00032.html#ga8f9445f1808b7aa80535aec7d38de6bb...

From the Teensy usb MIDI documentation https://github.com/PaulStoffregen/cores/blob/master/usb_midi/usb_api.h void sendAfterTouch(uint8_t pressure, uint8_t channel, uint8_t cable=0) { send(0xD0, pressure, 0, channel, cable); and void...

I'm testing some new LED strips (HD108) with Teensy 3.2 and I'm noticing some unusual Animations begin very smooth and beautiful, over time (after one minute) we can notice looking at the LEDs it gradually starts decreasing frame rate. Resetting...

Instead of TeensyThreads or FreeRTOS, I use a simple cooperative "OS" that I built myself, with mailboxes and queues for inter-task and ISR-to-task communication and this works very well for me. The underlying C queue is shown below, with each...

Apologies if I'm being a bit dense but I don't see how to install 1.59 for IDE 1.8.19. The instrs on the pjrc website seem to assume IDE 2.x on. Can anybody point me in the right direction?

Hi, Try https://github.com/tsandmann/freertos-teensy Follow installation instructions, and examples would work easily. Then make your own project. Another very good example is https://github.com/tjaekel/Teesny_4_1 You can find some post here...

For documents, use Google or other search engine. I think you are confusing the signal requirements on the RS485 side and the micro-controller side. The RS485 side can handle voltages in excess of Vcc. See data sheet. (Common mode range: -7V to...

Hey All, I am new to this forum & fresh to teensy usage. I was planning to build a software where I need the Teensy 4.0 in SPI Slave mode. I have got few questions after going through many of the forum discussions and library examples. 1. As a...

Thank you! Hardware platform is in the works, i'm trying to make it versatile and mod friendly: Teensy4.1 AK5552 + AK4552 ADC+DAC can be replaced with a separate module containing a codec + whatever it needs. I2S, I2C, differential ADC input...

Made an interesting discovery: it's possible to initialize the SDRAM even before any code gets executed, by filling out a DCD (Device Configuration Data) struct. The ROM processes it and takes care of programming all the SEMC registers when the...

I have a RPI RS485 CAN Hat Module so Should I use its Chip but I have doubt the the MAX3485 Chip runs on 3.3V right but the A and B Pins Side is working on 5V so does it not damage the MAX3485 Chip. Is their any reference doc you can share the...

this Level Shifter CKT works fine with the I2C pin but I am not receiving any output when Connected with MAX485 Chip Ckt on the master end . So do am I using the wrong Modbus lib for Teensy ?? Slave Code : (Teensy side ) #include...

I've built a synth playing multiple soundfonts using the wavetable.playNote() function. However I need to "Fine Tune" the pitch of the synth to other non-electronic instruments and I've not been able to find any way to do this. The wavetable...

Man you're moving on fast :) 1590XX is propably good choice as it's fairly common Hammond enclosure. And aluminium will provide shield. AK5552 looks like very high quality adc but for AK4552 I only found some obsolete part from Digikey and...

True to the title of the thread, I was wiring up the two new eyes I bought (see the previous post, #151). Now of course these new eyes have a different wiring layout than the previous eyes. So to test them out, I added jumper wires to the...

Thank you Kris.

Nice!

Or use one of the many MAXIM 3.3V RS485 chips.

Thanks - I changed it to 1349 to take it to C0 and it's more than good enough for my purposes! I really appreciate the help from you both.

That circuit should work fine for normal baud rates.

How about this MOSFET operated Bidirectional logic level converter ckt from this website mention below. Will it work? What if i use this between teensy 4.1 and MAX 485 Chip. Actually I am trying it now...

No, it's simple enough just to change the 536 to 1349 to allow going down to C0 - though as noted by @MarkT it's much better practice to use a const int with a name (and a proper comment) and then change every occurrence of 536 to that. It uses...
