    4.0/4.1 crystals and 1 more thing.

    Hey All, Do to the IC shortage and all, I need to know a few things to make sure I have selected the correct components. The crystals for use in the teensy 4.0 I selected what seems to be available FC-135 32,768KA-K0 I think it matches to the spec's the link it sent me too from here. The...

    4.0/4.1 crystals

    Anybody have idea what are the part numbers of the crystals used on the 4.0/4.1 teensy. Currently updating an old design from the 3.2 teensy to either 4.0 or 4.1 (4.1 less all the fancy parts) I tried reading the tops, but cant locate the product. And forgot how to determine the pF values...

    Custom Teensy 3.6 - K66 not booting

    PC will not see serial until you program something. When I get a new board, hooking it up the PC see nothing.. I then program it, the teesy loader does its thing and walla, serial pops up. I then can use the loader to do the rest of my boards. I looked over your schematic and the last one I...

    Creating pulse 5us width

    "It works great".. This is from the company that wanted this handset. Thus I duplicated the signals correctly! I tell you, that's a lot of pressure off this old man. With everyone's help, it amazes me what can be done. And just how great a program Paul has made with the Teensy. The 1st...

    Simblee Help.

    I had to use Simblee again and found arm-none-eabi-g++ had been updated which look as if it broke Simblee upload. I renamed the new to allow for the older one to work. Thanks for keeping this up and running.

    Creating pulse 5us width

    Ok, I like to fix the program flow for this project. It is working good, but I think using if else statements is kind of a problem. I use the if statement to digitalRead 1 of 16 inputs going low. I also in the statement added conditions to block out any other digitaReads from working...

    Creating pulse 5us width

    Live and Learn.. You can if you do not place a pulseIn(xxxx,HIGH) right after pulseIn(xxxx,LOW) Also, I know the code repeats at 75ms. So when I get a value over 74000 I should start my reads. I however loose the 1st pulse I think.. I had to stop and program a old Simblee chip to find out...

    Can't run project.

    This is amazing.. I have yet to have any bad loader chips when used in pre-production boards that I soldered components on. I have done a few.. over 25 if I recall. The only issue that the schematic software that I used to make the PCB pulled the wrong foot print for the IC. This has happen 2...

    Arm and Engage relays with 1 button

    Success... Works really good. Did lower the >1000 to >300 and works great. Thanks a bunch.. If -Then are good. I did use Switch Case on another project of which PJRC ends up selling a few bootloaders once in awhile. Note to Paul, If the 2800 project (not this one) goes and works with the...

    Creating pulse 5us width

    Well, I just compared the original to the teensy emulated device waveforms. I have 17 conditions in a IF and ese if's after 1st if statement. The action call voids to complete the waveform. So I have a start waveform and if no action of a button, defaults to a void nokey. If you press a...

    So I decided to try a SAMD21 type board using the same routine.. Wow what a difference.. It did not work as well, in fact it was pretty bad.. I could not get the pulse to 5 us at all. The waveform did a bit of breathing.. Kind of a wave at a game. I even tried all sorts of times and...

    Using Micros, and setting up for 5 off/5 on, I could never get to 5 us. It was like 6.9 us and would change width every so often. I set speed to 120 overclock and faster with pure code and LTO. The 3.5 handled it great. I'm playing with ShiftOut now but moving to SPI. Seeing if I can just...

    So I tried both my Teensy 3.1 and the 3.5 and found the 3.5 can produce a accurate 5 us square wave. I'm will now look into using SPI. I think I might be able to create 10000110 code or like to send. I looked at it yesterday, if I can make it 5 us wide. wish there was something like...

    Custom Teensy 3.2 Board: Board Not Recognized by PC

    Teensy Qt

    Works on the laptop fine. This computer is a new Dell and still reports can not upload and that it is not a Teensy 3.5 connected. The original Teensy 3.5 from the store reports good. Again, the bootloader on this board has the leads and is the only difference.

    Let you know, on a designed board with MK64FX512VDM12 and bootloader MKL04Z32_TQFP32, the software reports it as 3.1 and not 3.5. Thus, Teensy QT will not flash the software. Teensy Loader works fine. Thought I pass this info to you.

The older 3.2 I use to use would read the values from a system as 55 then 50, and last 42. This program would respond to each code and send a HEX code out. This...
