openstage's Issues

Is there a circuit drawing?

Hi.
Is there a circuit drawing?
Best.
Petro.

Currently way to debug an Uno that's on the USB serial interface only

Make new PCB design for timer-based version

The hardware timers work on only certain DIO lines, so once #8 is finished, we will need to re-design the PCB so that the steppers get their inputs from the right lines.

Non-PCB user settings files are using some old variables that no longer exist

Max pulse rate

The accelstepper library can't produce pulse rates in excess of about 4000 kHz but this fact isn't made clear to the user. So the stage may be moving slower than the user expects under certain circumstances.

Issue on connecting USB host shield with Mega ___"board.qc" fail to work

Hi, Rob! My name is Jason, a graduate student. After reading your paper and stage build, I am also quite interested in building my own motorized stage with relatively cheap motors to replace the expensive linear ones. The idea of using Joystick to control the stage movement is very innovative, which is also successful for the high precision gained. However, as I started to testing my PS3 controllers as a pure input device, I found it hard to connect it with my Arduino Mega. As I ran the board.qc file, it keeps showing me the error

USB Host Shield Quality Control Routine Reading REVISION register... Die revision invalid. Value returned: 00 Unrecoverable error - test halted!! 0x55 pattern is transmitted via SPI Press RESET to restart test.

(even after I pressed the Reset button several times). I am now using a Sparkfun shield and wiring the jumpers exactly the same as you did in the paper. On the other hand, if I ran the PS3USB file, then it'll show me "OSC did not start", which I am not quite sure what that OSC is. Luckily, as I tried stacking the Sparkfun shield on the Uno board with pin 7 of the shield connected to the Reset of the shield. It then works well (since the SCK,SIMO,MOSI and SS pins of both boards are on the same locations).

So my question is, is it the connection of SCK, MISO, SOMI AND SS the key point of this whole design? and why I should connect the pin 53 to the pin10 on the Mega board? (Since I am doing exactly the same as you did but have not gotten the same good result, and I found that pin10 is of no specific use) Is there any way else that I can do to succeed the Mega connection with the shield? Are there any notices I should pay attention to apart from the ones you mentioned in your paper? I am quite looking forward to your reply!
Thank you so much for your help!

Motion direction inverting

We need a way for the user to programatically set the motor direction in the settings. i.e. the stage should move in the direction expected by the user without the user needing to re-wire the motors.

When compiled with two axes only (1 and 2) it fails to start

OpenStage does not boot when only the first two axes are enabled but it compiles just fine.

Bluetooth lag

First, let me say that openstage is awesome. After frustrating SPI issues using Mega2560 + USB Host Shield, it was extremely easy to get it working after switching to a Mega ADK.

Using a PS4 gamepad via USB works very well, and while I can control the stage via bluetooth, there is significant lag (about 1 second). I'm wondering if other users have experienced this and whether there is a known solution?

Using the same hardware and running the USB Host Shield example PS4BT, hat positions are printed with no lag, so there must be something in the openstage code that is slowing things down.

Thanks!

Integrated completed moveToAccel_multiple.ino into OpenStage code

Requires completion of #7

The connectOpenStage function has no way of knowing that the connection was established.

Add OpenStage to Open Neuroscience

Hello!

We are reaching out because we would love to have your project listed on Open Neuroscience, and also share information about this project:

Open Neuroscience is a community run project, where we are curating and highlighting open source projects related to neurosciences!

Briefly, we have a website where short descriptions about projects are listed, with links to the projects themselves, their authors, together with images and other links.

Once a new entry is made, we make a quick check for spam, and publish it.

Once published, we make people aware of the new entry by Twitter and a Facebook group.

To add information about their project, developers only need to fill out this form

In the form, people can add subfields and tags to their entries, so that projects are filterable and searchable on the website!

The reason why we have the form system is that it makes it open for everyone to contribute to the website and allows developers themselves to describe their projects!

Also, there are so many amazing projects coming out in Neurosciences that it would be impossible for us to keep track and log them all!

Open Neuroscience tech stack leverages open source tools as much as possible:

• The website is based on HUGO + Academic Theme
• Everything is hosted on github here
• We use plausible.io to see visit stats on the website. It respects visitors privacy, doesn't install cookies on your computer
  • You can check our visitor stats here

Please get in touch if you have any questions or would like to collaborate!

Micro-Manager adapter?

This is an excellent project, I was wondering if anyone has incorporated it into Micro-Manager with success?
I look forward to hearing your thoughts.

Get moveToAccel_multiple.ino working

In the timer branch there is a testing function that can be used to make sure OpenStage can run with hardware timers. i.e. the motors need to rum smoothly for the required distance, etc. See the associated milestone for details.

The first thing to do, therefore, is to make sure that the motor hardware runs correctly using this function. Once all this works, we can integrate the ideas into the main code.
