Paul - very nice bit of code. This will be VERY useful to those who do Model 28 or 30 TTY interfaces. The 110 baud they ran at was not easy to get without some tricky bit-banging. �� ��

This company also provides an AMAZING editing package (Workshop4) that provides drag-n-drop widgets, and the code to run them is also created!
The displays can be standalone or talk to Arduino, rPI,...

I have just found this company (4D Systems out of OZ): https://4dsystems.com.au/

They appear to have a really nice line of intelligent LCD displays. I just ordered one from Mouser... not cheap...

OMG! The Mac... Being "difficult"?

Up until about 10 years ago (or so) I was an INSANE MAC BIGOT! :-) Back "in the day" one of the Mac calling cards was the ease of installation of software. ...

Did you look here: https://www.pjrc.com/teensy/datasheets.html

=A.

Have been browsing thru all the various libraries available here and just came across the PPM Library. My project was to move 4 steppers to follow a joystick which is indicating range and bearing of...

Hey! Thanks for the tip. So new to this AWESOME environment and there is so much to "relearn". :-)

I see it mentioned in the "Delay and Timing Functions" but do see a d/l link for it. Did a bit of surfing on Github - and MANY "Interval Timers" where found (!!) - but did not see one specifically...

Thanks for those details. I’m just beginning to “get” the wonders of the Teensy world. Wish I’d woken up to it about 3years ago... would have saved a lot of grief… LOL!

WOW! How does that work? Is there a version of Processing for ARM/Cortex?

I'm sure this is explained somewhere here - but haven't found it yet!

My project will be with a Teensy3.5 and I'd like to use the USB connector with which code is uploaded as a serial port for the...

I had 1.47 installed and all was working. But I did NOT install any of the included libraries as I have a rather LARGE collection from regular Arduino work. On the install of 1.48 I let all the...

OK - know I have most resent Arduino - just didn't know where to look for Teensyduino version. I generally work with MS Visual Studio so don't always see that panel. THANKS!

It seems to blend in very nicely with the Ardunio IDE... not sure where to see what version I have. :-)

@Quadrupel - where did you insert the startup patch in startup.c - that is a VERY busy file - don't want to break it. Also - I'm keeping a copy of the original..

Yes - I totally agree! New T4 user been on just a week or so - just beginning to see the depth that is here.

BTW - as far as 'bloat' goes using bitClear() or bitSet) - I got a disassembly listing on a Teensy4/Teensyduino test script (in VisualStudio 2019) - and each of those took ONE line of assembly code....

Well @quadrupel - you may have a beard grayer than mine - but I STILL disagree.

Perhaps in a heavy duty commercial programming environment... but for many Arduino and Teensy users I think the...

Sorry- do not agree with your assessment.

Every bit manipulation that can be done with the operators can be done with the functions. And I would not mind see several lined of such functions as I...

I've been programming about 40 years (GAK!) and still have not gotten used to the rather 'formal' definitions like uint32_t (which I 'get' while that is useful) but I'm still wondering about the...

Even after just digging into T4 (have has a 3.6 but never got the “round-to-it” to begin learning. The higher price of the 3.6 kept me out of the game, but going forward the T4 is only slightly more...

Ah - thanks for clearing that up. So I will be able to just keep my Teensy libs separate.

I'm sure other more active developers have a bigger library problem than a hundred, but the 'library'...

I see Teensyduino has it's own library location apart from the Arduino libraries. I have about a hundred Arduino libs and would rather not dupe them into the Teensyduino folder. I'd like to keep...

Hey - Have not heard of PlatformIO - will def check it out - THANKS!

Um - I have been using MS Visual Studio (from v2015 to now v2019) along with VisualMicro) for several years for all my Arduino work.

Now T4 (as do other Teensies) is working pretty good with...

Thanks Paul. I did take a pass at the T4_Beta forum. Quite a display of an impressive array of skills, dedication & effort I must say. Will make for a good study.

I think I’ve been away from the...

Thanks Paul! In the Arduino IDE all the register names were defined and they could be used in code. The Timers come to mind, as they generally had to be configured by setting various bits in the...

Yes - i'm well aware of that 3k page 1060 doc ( as you have mentioned last time I tried to ask this). I have it d/l and looked at it - Very impressive chip!

SO - since the Arduino never had a real...

After beating my head against the STM/HAL wall - I'm beginning to enjoy the simplicity of Teensy/Ard IDE.

Naturally this VERY advanced chip has a ton of functions not available in any other ARM...

Ok - so the answer is: There are no special functions in Teensyduino - it is just Arduino ported to ARM and if you want anything other than that - you find a library - or make one yourself. :-) ...

Ok - but that is not what I was looking for. I have those manuals - even the 3300+ page one for the chip on the T4!

What I'm hoping to find are the non-Ardunio functions that Teensyduino has...

The Teensy's (and esp T4) bring a host of new capabilities to the "performance-starved" Arduino user. :-)
Just wondering if there is any reference listing of the non-Arduino (ARM?) functions that...

Greets! I have made a search of posts but haven't found anything...

I fully understand "Not 5V compliant" pins is not to be trifled with - so just to be sure - if I want to use the T4 to...

Ok. As I said- guess I brought my question to the wrong forum. I had no real idea how the Teensy was set up to make life a bit easier vis the Arduino IDE. I’m sure that will be a great help as I...

I hear ya Paul! But I’m not trying to do any specific project at this point- just interested in how one uses the HAL libraries with the ARM chips. I don’t mind rooting thru those docs. - have a...

Ah yes - do have that book as a PDF. I think it only covers M3/M4 but the principles should hold up... but then again that T4 has such a bear of a system... dunno if that is going be that easy. ��

Yikes - Just grabbed the datasheet for the T4 processor - 3367 pages!!! And I thought the '328 was big a over 1100.... I feel a bit like the dog that chased the car - now that I caught it - don't...

Ok - not trying to dis the Teensy community or boards! Have had a 3.2 board here for some time and haven't gotten my 'round-too-it' to check it out until now. I don't have any prob with using the...

Heh - just trying to tinker and learn the mysteries of the ARM/Cortex world. These chips are SO powerful - just wanted to 'jump in' and see what could be done. I do access the various boards I have...

Yikes! Is it accessible to put in other software? All new to me! :-(

------------------------------------
It wasn't so much that I was questioning the capabilities of the hardware - I'm just now getting familiar with the Teensy products and wasn't sure how one...

Thanks for the quick reply Paul. Just learning all the ARM buzz words so sorry if a bit vague. I’ve done a fair amount of Arduino work, and want to move into ARM. I have been reading the HAL library...

Moving up from Arduino - have been LONG time fan of the ARM world. Now digging into the HAL functions for an STM32 board/chip. Have also been BLOWN AWAY by the specs of the Teensy 4.0! Have no use...
