Yep, that worked!
Curiously, I did not need to do this with Arduino 1.0.5.

Thanks again for your help.

Thanks for the screenshots. On studying them I realised I was looking at the Problems tab not the Console tab. It was actually working ok! Duh!!

I have now built and uploaded several sketches into...

Hi Headroom,

I think I am almost there this time!

Firstly, a minor point in the installation. At step 8 it is best to uncheck "Group Items By Category" before completing the dialogue box....

Understood. Thanks for taking the time to answer my questions.

Thanks, found it.

Wow, you've certainly put a lot of work into this. Why did you need to emulate the AVR SPI hardware? Could you not have just implemented the half dozen or so SPI API functions?

Hi Guys,

Thanks for the detailed responses. I did not intend to cause such controversy! I will try to answer all your points in one reply.



The Arduino web site clearly states:

1.5.2 is...

It doesn't seem right to have to use an (obsolete) unsupported beta of Arduino.
Does the Teensy Extension File fix the Mac upload problem? If not, it is unusable for me.

Paul,

Your Makefile appears to be incomplete, it does not pull in the various libraries. You recognise this in a comment:

# automatically create lists of the sources and objects

Hi Headroom,

Your instructions seemed well written, so I thought I would try Eclipse. Unfortunately, it has not been a happy experience:
1. I downloaded the 64-bit version of Eclipse (because OS...

Has anybody (apart from Avenue33 that is) used embedXcode?
If so, I would appreciate learning how you have got on and whether or not it lived up to your expectations.

Thanks for your help.

Thanks Paul.

I found the SPI code, but i'm even more confused now. It appears to be for the AVR chips. How does it relate to the MK20 chip?

OK, I located these functions in .../cores/teensy3/avr_emulation.h and can see how to call them. Should I call them before or after calling SPI.begin()?

As an aside, where is the SPI library code...

I was using CoolTerm to monitor the serial output and leaving it running while I uploaded the new code. If I use the Arduino Serial Monitor instead, Auto-reboot works perfectly. Many thanks.

Hi Paul,

Teensy Loader 1.16 seems to have fixed my upload problems. It works ok every time now. Many thanks.

One minor point. Auto-reboot no longer seems to work. I have to press the button on...

Thanks guys,

I will try this out.

BTW, glad to see Teensyduino 1.16 is released - hopefully this will cure my Mac upload problems.

Hi all,

The Teensy3 pinout drawing shows a second copy of Serial1 signals and some SPI signals. I checked the MK20 datasheet and these are valid pin routing options. Is it possible to make use of...

I've had my Teensy3 for a few days now and am having the same problems when uploading. Sometimes it works, sometimes it doesn't. I have a 2011 Mac mini running Lion (10.7.5).

When will Teensyduino...

My local electronics component supplier stocks two 2 x 6mm cylindrical 32.768kHz crystals. One is specified at 6pF load capacitance, the other at 12.5pF load capacitance. Which one should I choose...
