I guess the dimension 0.06 should be 0.6:

Do you know how the company Gaze Electronics can be contacted? It seems like I don't find any website.

I also use AVG, it warned me yesterday about a threat called SCGeneric.HZL in file ImgConv.exe. AVG was updated automatically 20 minutes before this warning appeared.

It's also possible to convert 0-5V voltage to 4-20mA current, which is more stable over long distances. Here are a few examples of voltage-to-current converters: http://www.szsunyuan.com/uploadfile/2015/ISO%20V-4-20mA%20V2.0.pdf...

And you also need to add Teensy3Clock.set(now()); after setTime(10,10,10,11, 12, 2017); otherwise the RTC clock is not updated. The setTime() function changes the clock in your running sketch, not in the RTC.

Check that you still have this line in your code: Teensy3Clock.set(t);

You need parentheses around the whole 'if' conditions, that means: if ((flag1 == 1) && (x == 0)){ or: if (flag1 == 1 && x == 0){

Yes, the CS signal is active low, so you pull CS to wiz820io high and CS to 595 low when you want to communicate with 595.

You can try to increase the size of the serial buffer: https://forum.pjrc.com/threads/35149-Increasing-Serial-TX-abd-RX-buffer-size-to-1024?highlight=TX_BUFFER_SIZE https://forum.pjrc.com/threads/38796-Teensy-3-6-Serial-Buffer

You can check this thread for UART high speed rate: https://forum.pjrc.com/threads/23687-Teensy-3-0-UART-datarate?p=81566&viewfull=1#post81566

UART speed is usually much lower than 3Mbps :-) What kind of UART device do you want to use?

I see you are working on improving the Ethernet library regarding W5500 chip, thank you very much! https://github.com/PaulStoffregen/Ethernet/commit/ee1eacf88b4c7d5e0b0a7f7ea1c94cc8ce8de7e1 If I understand correctly, the Reset signal is not needed any more. Is that correct?

Thank you for quick clarification! :-) It may be a good idea to write something about it on https://www.pjrc.com/teensy/td_libs_SPI.html.

I tried to go through most of the long thread https://forum.pjrc.com/threads/34808-K66-Beta-Test, but didn't find any information about following question: Traditionally the SPI CS pin 10 must be used as an output to avoid conflict with SPI functionality...

@ Epyon, Ben and Theremingenieur Thank you very much for your advices! :)

@Theremingenieur Thank you for the schematic, it looks nice :) I will probably try this circuit with a LM258 op amp. I have two questions: Is it better to use a diode between the "+" input and the +5V rail as shown in your diagram, rather than a 5V Zener diode between the "+" input and...

Connection between 4-20mA sensors and AGND Analog Ground Hello, I would like to connect several 4-20 mA sensors to Teensy, see attached schematic. Is it correct to connect the 50 ohm resistors to AGND (Analog Ground), shown with green color on the schematic? Is there a limit for the allowed...

That sounds nice!! :)

Maybe the problem is similar to the one in this thread: https://forum.pjrc.com/threads/28889-Teensy-3-1-analogRead-problem

The pad hole diameter is about 1.0 mm, and the distance between pads is basically 2.54 mm (100 mils).

Serial LCD touch display with WYSIWYG editor Since you work with a serial LCD display, you may also be interested in the Indiegogo campaign for the Nextion, a UART LCD touch display (HMI) with a WYSIWYG editor: https://www.indiegogo.com/projects/nextion-a-cost-effective-high-performance-tft-hmi...

This problem seems to be related to FTDI chips, but the Teensy doesn't contain such a chip.

I really appreciate your quick support. I sent an email to Robin. I cannot remember having special problems when using other devices on this port. I usually connect my phone or USB memory sticks to this port, and the data communication works correctly. To be on the safe side, I will use another...

It is Windows 7 64-bit.

I just followed the "Getting Started" instructions (https://www.pjrc.com/teensy/loader.html) and Tutorial 1 (https://www.pjrc.com/teensy/tutorial.html). Yes, I accepted and it installed successfully. I tested the HelloSerialMonitor example and it worked correctly. On the second PC with Windows...

Hello, I've started to test my first Teensy 3.1 that I ordered from SparkFun. - I connected a USB cable to Teensy, then the LED was blinking. OK. - I installed Teensy Loader 1.17, uploaded blink_fast_Teensy31.hex on Teensy, then the LED was blinking fast. OK. - I installed Arduino 1.0.6 and...
