Can Codewarrior IDE be used for Teensy 3.0, or any other simulators for T3 and Win7??

Can Codewarrior IDE be used for Teensy 3.0, or any other simulators for T3 and Win7??

Hello:
I'm finding the serial comm very intermittent on my Win 7 Pro platform, and I really want to use the tiny T3, so I'm looking for IDE alternatives.
I'm using the serial only for debugging, but the Arduino interface has serious drawbacks in this area, like I cannot single step, nor really stop at a certain place,
nor examine register contents without a hello world printout...

Has anyone tried to get the CW10+ IDE to connect with the board, I'll try today, but I thought I would ask first?

Are there any other simulators with a fair to good reputation for working with USB serial that you have tried and liked?

Is there any way to make Teensyduino other than trying the switch USB type from Serial to Keyboard+Mouse+Joystick, which I have tried with the same intermittent results.
The results are that sometimes the PC connects to the board and other times not. If I unplug the board, or close and reopen Arduino, or reset the board switch, sometimes,
one or all will work, other times not...

I'm using Teensy 1.15 and Arduino 1.0.5. with Teensy 3.0.

Thanks and World Peace..
Tim

What specifically happens in the "not" case? Can you post the specific code you're uploading and a more specific description of the problem?

Sure I can.
1. Arduino is opened, and the connection box on bottom right message is "Teensy 3.0 on (USB Port)"
2. Upon pressing the "Upload" button, the sketch is compiled successfully (code below) and uploaded to the board, message is "Done Uploading"
Teensy in Auto mode has messaged "Programming" and "Reboot OK".
3. Board is running user code.
4. Tools -> Serial Monitor is selected and nothing happens except this error message:
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Arduino: 1.0.5 (Windows 7), Board: "Teensy 3.0"

Please press the RESET BUTTON on your Teensy to upload your sketch. Auto-reboot only works if the Teensy is running a previous sketch.

5. In the current action text box, the message "no connection" is printed.
6. The code is here:

#include "IntervalTimer.h"
#include <IEEE1547.h>
#include <ADC.h>

/* Test code

// IEE1547 timers needed:
1. ADC timer for one sample every 20usec
2. Millisecond timer for real time loop and for IEEE1547 trip point time compares

1. Do RMS calculation every ac cycle 16.6 or 20msec, average result for two cycles
2. After 10 cycles of failure, set 10 cycle fail flag
3. After 1 seconds of failure, set 1 secs fail flag
4. After 2 seconds of failure, set 2 secs fail flag
5. Base real time loop on input zero crossing positive or negative going, either approx 8.33 or 10 msecs

After uploading this to your board, use Serial Monitor
to view the message. When Serial is selected from the
Tools > USB Type menu, the correct serial port must be
selected from the Tools > Serial Port AFTER Teensy is
running this code. Teensy only becomes a serial device
while this code is running! For non-Serial types,
the Serial port is emulated, so no port needs to be
selected.

Forgot the specific description you asked for.
The code usually uploads to the board ok. At least 95% of the time.
The problem usually is that I cannot then see any debug output, which is the about the only debug tool I know of in Arduino environment...
I do use hardware triggers for timing, but it's hard to read out values in such (especially 16 bits of analog or 64 bits of digitial values)
when NOT using the serial print feature.

more specific description of the problem?

Another problem is that sometimes the board needs to be powered down, currently being powered thru USB
So unplugging and replugging the USB cable will result in the message "Serial port not found. Did you select the right one..."
When Tools --> Serial Port is pulled down, the correct serial port is not listed. Windows Device Manager is displaying
the "USB Serial (Communication Class, Abstract Control Module) (COM11)" but the pull down only displays COM10.

I've tried on two Win 7 machines, one Pro and one Home versions. Maybe I have the wrong USB serial driver?

Thanks
Tim

Has anyone tried to get the CW10+ IDE to connect with the board, I'll try today, but I thought I would ask first?

I figured that someone might be interested in the answer...so here 'tis.
Freescale has a pull down menu for the boards they support with the Kinetis chip (Teensy 3), and of course the T3 is not on that list. Not sure
what it would take to get on that list, maybe easy, maybe not? The company does make what they call an Arduino footprint compatible board with the same chip
called the Kinetis Freedom board, that will talk to Codewarrior, but then you have the traditional micro/software dev platform, with all of it's power and all of
it's pain, the pain being the learning curve and the extra time (in weeks and months) it will take to develop your applicatioin.

All I really need is a stable serial comm so I can debug my application. Or ANY stable comm. I hope is does not sound elitest to ask to see richer debug tools like the ability to set breakpoints and stop a program at a certain point. Also nice would be the ability to look into memory locations statically.

In theory, if you can get CodeWarrior to create a .hex file, you could open that file with Teensy Loader to load it onto the Teensy3.

In practice there are probably lots of little ugly details to resolve. The first issue is probably whatever startup and initialization code they use. These Kinetis chips have a pretty incredible number of options. There are lots of ways to clock the chip. Teensy 3.0 uses a 16 MHz crystal with the PLL to create a 96 MHz clock, which is then divided to 48 and 24 MHz for the bus, usb and flash clocks. Their code might default to an 8 MHz crystal, or a 32.768 kHz crystal, or maybe even the internal oscillator? For the slow sources, the FLL is used instead of the PLL. Getting the startup code correct for the 16 MHz crystal is probably the first big obstacle.

Presumably you're using Windows?

On Windows, the serial driver isn't nearly as robust as Mac and Linux. Once it's working, it tends to work quite well, as long as you never unplug the cable or press the pushbutton while the port is open (clicking "Upload" in Arduino automatically closes the serial monitor before attempting the upload). If you do that, it leaves garbage in the Windows Registry which then confuses it the *next* time Teensy3 appears. That's extremely confusing to troubleshoot, since things you do that are correct don't have the intended effect until done twice in a row! It's a really poor design on Microsoft's part.

On Windows, the simplest thing to do if you're having serial troubles is set Tools > USB Type to any of the non-serial options. The serial monitor will still work, but it uses a HID interface to emulate serial. Microsoft's HID drivers are much better. Just set to Keyboard+Mouse+Joystick, then upload a couple times. You'll have to press the button at first, but once you're off serial and the new hardware wizard is happy with having seen the new device once, things will work much better.

Thanks Paul.
Yes I have tried that on both of my Win 7 machines (Pro and Home) with same intermitt results.

Funny that now I have done a sequence
of maybe 100 or more edit/compile/upload/debug cycles on the T3, I am starting to get a sequence that *usually* gets me a usable Serial Monitor
window. I say usable because sometimes the monitor does open, but does not print. Or it opens but hangs the Arduino program. So while
I may have a development platform that is not robust, it may still be quicker than going the traditional micro/IDE/debug route, which often takes
many days or weeks just to get a chip running user code. One of the keys is that after upload to the board, the Windows Device Manager needs time to update the USB serial status,
and if you wait until well after the refresh time...all goes better!

Tim

Can Codewarrior IDE be used for Teensy 3.0, or any other simulators for T3 and Win7??
