Hi, I saw this link with the cytron maker pi daugther board. I like that the pico's PCB design puts a SMT edge mounted pad on each header pin. This cytron pi maker can then solder a break out style board directly with out any connectors. Neato...

Hi, I am concerned about that glitches that would occur on adjacent pins when toggling at high speed rather than EMI emissions which is another issue maybe have to be handled externally by the designer. Also the impedance mismatch on the shorter pitch header would be better using tighter...

Regarding the teensy 0.1" header which is so fantastic for breadboarding stuff, but to go faster maybe denser is needed. Maybe make a teensy with 0.50" posts, and sell adapter board for 0.1" header to make bread boarding soldering easier. Also for higher speed I think at some point more...

USB C connector for more power to power stuff, More ground pins for better SI return paths, I dont like using pogo pins to get at extra pins, As an idea use tighter pitch connectors on new teensy, but offer a 0.1" pitch adapter for bread boarding stuff.

The encoder returns integers so the 1st issue your not going to get floating point. To debug I would print the TempSel.read(); every time it changes and print the read values without subtracting to see what the values you get when you turn the encoder. It should become obvious after a while...

I figured u guys could get a good laugh at my expert soldering skills and my total commitment to cleaning flux of my board.

@mjs513 your script work on my setup too. Thanks. I debugged you code vs my example and it seems the baud rate was the issue. The baud rate should be AFTER the begin() method. I tried setting the baud rate before the begin statement that does not work. I was so fixated on the fact that I...

Ok, so I just toggled pin22 in a loop to create a 1.1mhz clock on (CTX1) high and low using digital write in a loop. I see it go high and low, I also see RX path going high and low back on pin 23. I also see the same signal pin 0 CRX2. So I think my setup is fine.

I'm using two IFX1050GVIO chips. I have it on bread board with just bread board wires. I currently do not see any data coming out of teensy TX pin so I'm not sure if it matters to see the mass ball of wires. I mean if the tx was toggling then yes SI issues would be next to look. But since no...

Thanks Your right it switched the board type after install. Ok it compiles fine now but same result. I scope to tx and rx pins at both CAN1 and CAN2 and they a driving static hi level while the loop is going. (pins 0,1 and pins 22,23). There is no messages during the setup and I see the...

Hi, I downgraded to 1.47 beta5. I was on release. I started on release and cloned the FlexCAN_T4 repo so I dunno if this is related. Anyways, I get an error during compile for beta5: E:\arduino\libraries\FlexCAN_T4/FlexCAN_T4.tpp:17:27: error: 'CCM_CSCMR2' was not declared in this scope...

Hi, Thanks for responging. >Can you try that test on 1.47beta5 teensyduino? Ok will try it out. >do you have resistor 120 ohm on the line? yes have two IFX1050GVIO transievers hooked together. With 120oh resistors at each end. I measure 60ohms . When I say the TX lines aren't toggling...

Is it possible to include a simple test example for this. Hi, Is it possible to include a simple test example for this? I tried to use the example from existing FlexCan but I see no read data. So I found during debug there is no output on the TX pin its stuck high- I see no data toggling on...

+1 vote for board outline drawing official on the web site. It amazes me how good the Teensy hw and sw is, but then buries it under their horrible website, or simply doesn't document it.

Thanks for the note. Its been so long I chuckled to myself when I saw the forum update me. Actually one thing to note is that I think the code I originally reads SCL as pin 18 and SDA pin 19 and the comments are wrong. The funny thing is I mistakenly wired it backwards on my setup and wrote...

Hi bboyes, Thanks for the explanation and links.

Hi I have some noob questions. Q1: What is the purpose of the 100ohm resistor for the LED pin on the pjrc store page? Do I damage the display if I direct connect the LED to VIN supply? Is the LED pin a DC power supply input? Or is this a high impedance voltage controlled input to control...

Thanks KurtE. So basically SetCS (pin) sets a mux so the IO pin takes on the alternative function CS and its pin returns the PCS mask. I find it misleading however that there is no support for the CS pin in the transfer function. Its kind of a misleading function name. A new user will...

Does anybody use the hardware CS feature? The documentation on hardware CS function is unclear as all the examples just manually control CS. Is it proper to call SetCS() before or after SPI.begin() in the setup?

Ok thanks alot guys. I purchased a few 3.6 boards to play around with, but if I had to make a decision today I would stick with teensy 3.2 despite all the advancements in the 3.5/3.6 boards. I sure things like these i2c issues are fixable eventually but its hard to tell without some kind of...

Hi, Wow! I have not checked in awhile and I see two interesting teensy 3.5 and 3.6 boards. Christmas is early. I am looking at a new project which I need to control an I2C and SPI bus which I know the teensy 3.2 will work, but what about these new 3.5 and 3.6 boards? When I checked PRJC...

Hi, I always wanted to get a 3d printer, but I have no time nor space to do it. So I hired somebody to do it for my teensy. I have been toying the idea to replace my sluggish PC usb to i2c adapter with a teensy, but I wanted but the teensy in a box. I learned some stuff from this proto build...

Thanks. Does anybody have some real world experience with protecting the program memory on a teensy. My guess is this is not something end users should do directly since the bootloader is probably going to get messed up with this.

How secure is the teensy? I was wondering how easy would it be for somebody to copy a program flashed in a teensy and copy it to another teensy from an IP protection point of view. Can you prevent reading the program memory?

I am sharing my I2C sniffer I made for my teensy 3.1. You can basically attach your teensy to an I2C bus SCL0(pin19)and SDA0(pin18) and it will dump out the i2c commands to the serial port. The following is a sample output watching the Linear Powerplay GUI with their 3880 power controller...

Hi, I made a simple i2c program to sniff 2 IO inputs looking for a START condition. Once it sees the START it then records changes on the 2 pins in a tight loop. When it sees the STOP condition, the raw data is then decoding into human readable text i2c command via serial port. It works well...

Yes I did that. I see all my i2c devices when the timeout is set. Using the scanner without it will hang somewhere in the i2c_t3 library. No output and the led stay lit. Are you saying you can download the latest v8 on the website and run the scanner example without hanging? I have two...

Request fixing the scanner example Hi nox771, The i2c scanner example hangs. I'm not sure who is responsible for the scanner example, but if I use the i2c_t3 library, the app hangs on two teensy 3.1 devices that I use and another user reported it. I believe the default behavior of the i2c_t3...

I just debugged the same issue. I just debugged the same issue for another new user. I'm gonna ask the developer to fix the example because it makes it newbie unfriendly to hang like this. I added the following command to the setup() to fix. void setup() { pinMode(LED_BUILTIN,OUTPUT)...

Yes this change log info would be verbose. I mainly wanted some way to know which version was installed on the PC.

A text file containing the teensyduino revision and change log. I could not find one on my windows install.

Hi immortalSpirit, I'm newbie to tweensy and K20 chip. This post was very useful. I trying to learn more. Maybe I'm completely wrong here, but I disagree with one of the statements. The assertion that the K20 function has a feature to do IO port to pin mapping. > The ARM core has 5...
