QUESTION

Do you know how to emulate holding down a keystroke for any period of time, then releasing it later?

Asked 2020-Nov-29 at 14:53

I'm trying to emulate pushing the keyboard V key down while using BASS library to automate Voice Activation push to talk. I've got the BASS library working, just can't get the keyboard to simulate holding down a Key for any length of time!

Edit: I am trying to get another application ('TeamSpeak 3') to recognize my Key Press & hold as a hardware based Key Press & Hold rather than a software based Key Press & Hold. To help simulate a Push to Talk via my application. I will openly have the source code for anyone that wants it, but I will not be publishing my application for any reason. It's for my personal use and It's out of curiosity if it would work? I understand that any kind of abuse of this kind of app I take as my own personal responsibility.

Edit2: I have done extensive research. I figure I'm going to have to either use my old Android handheld or a Raspberry Pi. I have a Raspberry Pi Zero, so I am going to see if I can create it as a hardware keyboard. I'll write a program in Delphi to interface it (I have Delphi 10.4.1 Enterprise and hope it will work with Raspberry Pi's linux version.) I have a vmware Debian and Ubuntu os on my computer that I could pre-compile it with? Anyhow the article is here: https://randomnerdtutorials.com/raspberry-pi-zero-usb-keyboard-hid/

I'm going to go ahead an allow the answer below, because it basically does what my previous request says. To go further than my request requires a lot of work. I'll give an update if I can get it working properly.

(Delphi 10.4.1 / Target Windows 32-bit)

I designed a simple example where when the user click the mouse on a TButton, it simulate a keystroke every 250mS until the user release the mouse button.

The OnMouseButtonDown starts a 250mS timer, the OnMouseButtonUp stop the timer. The OnTimer send the keyboard event. The timer is also stopped when the mouse leave the form.

QUESTION

Can a USB 3 Host machine be programmed as a USB 3 Peripheral (or a HID keyboard)?

Asked 2020-Apr-20 at 13:35

What I want to do:

An AI program on a host machine, reading inputs from a camera sensing the screen of the target machine and outputting controls to the target machine via USB connection--programming the host machine's USB host as a USB peripheral connected to the target machine.

What I want to do step by step: (is it possible to implement the steps below?)

Have a host machine A and a target machine B.
Connect A and B with a USB 3.0 Type-A male-male cable.
The USB connection shows up as an HID keyboard device on B.
Write code to simulate key presses on A that sends to B.
(Eg. calling press('F') on a program running on A would type F to B's input)
It shouldn't require any program installed on B.

Suggestions in ascending order of feasibility:

USB Gadgets

You are using linux, so the default way would be to create/configure/load a gadget driver. Have a look at this tutorial, though for a raspberry, should work on your PC too. However, I could not find any information regarding the use of USB3 - the tutorial assumes your host is using one of it's OTG ports, which your PC most likely does not have. So whether this works with your USB3.1 Type-A-to-Type-A connection you'll need to test.

USBIP

The idea of sharing USB devices (not just keyboards) is not really new. With USBIP you can "export" any local USB device to the network, and your client will need the client-side USBIP driver to access the keyboard.

Dont bother with USB at all, just use Ethernet

I'd simply write two userland scripts/programs that send/receive+execute the keystrokes. Very easy to implement, you're probably familiar with python anyway.

If you absolutely cant have software installed on the client-PC and your Type-C-to-Type-C connection doesnt support USB Gadgets, there's another way. It basically involves the use of two USB-to-serial adapters (~15$) and a serial cable. While this wont be enumerated as a keyboard, but rather as serial port, it's the lowest-effort solution to transfer data without additional software on the client. Both computers will just do file I/O. If your computers still have COM-ports, you can even omit the serial converters!

QUESTION

Is there a way to tell if a MIDI-Device is connected via USB on iOS?

Asked 2018-Jun-01 at 06:12

I'm using CoreMIDI to receive messages from a MIDI-Keyboard via Camera Connection Kit on iOS-Devices. My App is about pitch recognition. I want the following functionality to be automatic:

By default use the microphone (already implemented), if a MIDI-Keyboard is connected use that instead.

It's could find out how to tell if it is a USB-Keyboard using the default driver. Just ask for the device called "USB-MIDI":

I ended up using the USBLocationID. It worked with any device I tested so far and none of the users complained.But I don't expect many users to use the MIDI-Features of my app.

I'm currently trying to emulate a keyboard with my pi zero w following several guidelines e.g., https://www.rmedgar.com/blog/using-rpi-zero-as-keyboard-setup-and-device-definition (all 3 parts) or this https://randomnerdtutorials.com/raspberry-pi-zero-usb-keyboard-hid/.

It seems to work but I can only make it type lower-case characters and I have no idea why. So e.g., with this code line (taken from the rmedgar guide)

When you're sending an HID report with a capital letter in it, you need to make sure the modifier bit for the Shift key is set to 1, just like on a real keyboard where you type capital letters by first pressing Shift. It's usually represented as a single bit at a fixed location in the report, not an 8-bit code. I don't know the details of the API you are using, but you should search its documentation for keywords like "modifier", "shift", "ctrl", and "alt".
