Great, the new controller works already. I need to clean up the code and optimize some parts but this makes good progress. Just curious Is this going to be an art installation? Yesterday I ordered one of those...

Currently not, but most probably this should be possible in a couple of days. I'm afraid playing around with this is just wasting your time, the current design is simply not capable to do this. Anyway, I'd be...

The TB6600 like most of the "larger" drivers has optocoupled inputs for the control signals. Driving them with 3.3V is very borderline. They state a 3.3V compatibility on the website but not in the datasheet? As...

Sorry, currently this is not possible. The library was designed to efficiently move a bunch of motors synchronized to a target position. It precalculates all movement parameters before the run. Changing those parameters...

Here you are: Sounds great! When you fixed the issues, would it be possible to get a copy for the examples folder (Pull request would be even better)? Looking forward to see your results, would be a really...

Ok, tried it with pulseIn, worked as well. It is a bit difficult to obtain a return value > 255 by just touching a pin with a wire but it finally gave me a result of 601.

I can not reproduce your problem. To check, I replaced your call to pulseIn(...) by a constant (1500 as you said...) uint32_t read_afew(uint32_t howmany) { uint32_t val = 0; uint8_t i; for (i = 0; i <...

What you are looking for is probably a motion planner. I.e. you give it a list of 2d (3d) data and it then generates movements from point to point without stopping in between. Unfortunately this is something quite...

@frmdstryr: As discussed yesterday, I splitted the original StepControl class into the abstract base class StepControlBase and derived the new StepControl from this class. The code is uploaded to the development branch...

Yep, this is exactly what I was thinking of. I would implement a base class with all the house keeping functionality and the Bresenham part. I'd add two abstract members, say start and updateSpeed. You would need to...

Yes, thought of that but the need was never big enough to really implement it. I could offer to implement a hook function which will be called whenever a new acceleration value is needed. You could then implement any...

Just my personal opinion: I don't think it makes sense to "fix" anything here. If one wants to use any function from the standard library which needs to write / read from the standard streams in an embedded...

In fact it looks like it crashes when it tries to print the error message...

Just for fun: If you define _write() you can also use the normal printf(). #include "Arduino.h" #include "stdio.h" extern "C" { int _write(int handle, char *buf, int count) { Serial.print("Written...

I can answer the first part of your question (not the second one...) It wants to output error messages: This : invalid option -- `-x' was generated by getOpt(). IIRC there is a compiler switch generating...

Sure, the code obviously was not meant to be functional. Here a working example. OMG, writing this example felt like a flash back to the 80ies :-)) Never liked this getopt thing. And no, I also can not think of any...

The libc which is linked in (newlib?) doesn't provide an implementation for _write(). This perfectly makes sense because the library can not know how to write anything anywhere on a given embedded system. So, you have...

New features in v.0.9.0 Additionally to vsCode, VisualTeensy now supports the ATOM editor as alternative target editor. For those who like builds as close to the Arduino IDE as possible I implemented Frank's...

Sort of, I didn't find out yet how to switch of word wrapping in the output window of vsCode which makes it even worse :-/ I somehow prefer the clean output of my makefiles :-)

Taking up Franks idea to use the arduino-builder instead of makefiles I added an option to VisualTeensy which generates vsCode projects using the arduino builder as build system. You can select the corresponding option...

Glad to hear that it works now. Have fun with TeensyStep!

If you can post a minimal example sketch showing the effect I can try to reproduce and dig further into it.

Which drivers are you using? Datasheet? It could be that the 3.3V of a Teensy are too small to drive optocoupled inputs. Here a thread which might help:...

Just to make sure that Teensy and scope are working, I'd test if this gives 10µs pulses on your scope: constexpr int pin = 0; void setup() { pinMode(pin, OUTPUT); } void loop() { digitalWriteFast(pin,...

That looks like some electronics problem. Can you measure the pulses without anything connected to the pin?

StepControl has two template parameters to set the pulse width and the acceleration update interval (both in microseconds), The pulse width defaults to 5µs, the acceleration update interval to 5000µs. If you want to...

Looks like you are reading beyond the array limits. Shouldnd't your condition for stopping be "if (posNr == nrOfPositions)"? The number stored at "targetPositions" might be huge, so that the last move takes quite long...

That obviously depends on the speed from which you want to decellerate. Acceleration of 500000 means that you would ramp up/down from 0 stp/sec to 500000stp/sec in one sec. For any practical applications this is very...

The problem with this is that the motors can not be run synced since during the acceleration / deceleration phases of the spindle motor they are necessarily out of sync. You can however use two controllers and sync them...

So, if I understand correctly, you want to start both motors together. While the axis motor keeps running you want the spindle motor moving back anf forth. After some cycles of the spindle motor you want to have both...

Yes, I've seen that post and thought: "since I don't like the Arduino Build system I'll stick with my makefiles!" :) "Dem ein' sin Uhl is dem annern sin Nachtigall" as they used to say :-) It is always good to have...

Just tried to compile a existing VisualTeensy generated project with Sublime and it works nicely :-) If anyone is interested in a quick experiment you can do the follwing steps: 1) copy the code below in a file...

Looks like a winder application? Maybe this thread https://forum.pjrc.com/threads/50148-Teensy-3-6-Interface-a-Microstep-driver-which-uses-5V?p=180627&viewfull=1#post180627 post #32 to #40 can help?

CTRL+SHIFT+B opens the "Terminal/Run/Build Task" menu. The menu remembers the last selection. So after the first time all you have to do is "CTRL+SHIFT+B RETURN" to trigger a rebuild followed by an upload. No need for...

Did you set the path to the TyTools correctly (settings tab). You can check in the generated makefile. The variable UPL_TYCMD_B should be set to your TyTools folder ...

Perfect, let me know if you find other issues or things to improve.

Can you give that one a try? https://github.com/luni64/VisualTeensy/releases/tag/0.8.4

I think I already found it. There is an issue with assembly files in my makefile. I'll fix it and update the repo at github. Needs an hour or so.

Hm, compiles without a problem here. Can you try a minimal example showing the problem and post or pm the sketch?

Just gave it a try, for the audio lib you would need the following libraries: Hope that helps

dspinst.h seems to belong to the audio library? Did you add the audio library (and its dependencies) using the library tab?

@Hughby: thanks for the pointer. Yes, I know, there is a couple of issues regarding first startup. Also the library manager is very basic at the moment. Unfortunately, I was busy the last 3 weeks with an urgent project...

This is how my editor looks like. Red: Attach file, blue: code tags.

Thanks a lot, hope that I can work on VisualTeensy next weekend. If you zip your *.rtf you can upload it directly to the forum (You need to switch to the advanced view first)

Glad that VisualTeensy is useful for you. Would it be possible to send me that tweaked Linux makefile? I could then add a "generate Linux compatible makefile" option if that would be usesful.

You can use TeensyDelay for that kind of tasks. Basically you could do the following: Set the pins or whatever you need to do Trigger one of the 8 delay channel with the required "reset" time In the callback...

@killkrt: I had a quick look at your makefile and code and have the following remarks: In your main.cpp you define the function int main() { setup(); while( true )

With your IDE hex I get: Interestingly the "Microseconds for one run" and the Dhrystones per Second" are exactly the same as I get with VisualTeensy. Anyway, since the differences are very small (100018/100008 =>...

Did a clean compile with the IDE (1.8.5, Settings: 256MHz, fastest + pure + LTO) which gives : Dhrystone Benchmark, Version 2.1 (Language: C) Program compiled without 'register' attribute Please give the number of...

Tried it, works without problems for me.

Hm, checked everything found no differences in compiler and linker flags. Here my output. Micros Run Time: 100018 MilliSeconds Run Time: 100 CycleCount Run Time: 25604700 F_CPU: 256000000 Microseconds for one...

Great that it worked without problems. I tried your attached benchmark with the same settings as you suggest on two T3.6. Both gave 100018. The result seems to be somehow dependend on the hardware? Anyway, I'm...

No, A0, A1... are defined in the core library and can be used without problem. The code you posted simply has syntax errors. The braket after loop() ( should be a brace { You forgot the last closing brace } ...

The code in the linked thread should be quite current but it only contains the two drivers. If you are interested in the complete project including the hex parser and the actual downloading you can download a zip here:...

The change allows the user to attach a callback function to the controllers. This callback wil be called whenever a controller finished a movement which can be useful for lot of things. You could simply switch an LED on...

As requested recently I uploaded a version with callback functionality (https://github.com/luni64/TeensyStep/issues/18). The callback function is called whenever a move is finished. If you want to give it a try you find...

Changing the target position of one motor during the move is not a principle problem, but the main design goal of TeensyStep was to move a couple of motors in sync. If you change the target of one of the synced motors...
