![]() In order to avoid conflict between the "USB pins" and the "I2C pins" (not used here) the usbconfig.h re-arranges the DATA+ and DATA- pins from the regular ones to a different pair. The input pins are also different than the ones in the post, since I was using code from another project ( NES Mini Controller USB Adapter for attiny85) I wrote some months ago. Some changes need to be done to modify the CPU speed (also fuses!) among with the use of an Oscillator Calibration function. ![]() Since I'm using an attiny85 I needed to change a few things in order to make the v-usb library work with it. When you want to stop doing this just stop the macro. Everytime you press ctrl-v a the copied number gets +1 and that new number copied to clipboard for the next paste. If you want to copy from a textbox (in this example textBox1), this is what you need: Clipboard.SetText (textBox1.Text) //To copy your text to your clipboard Clipboard.GetText () //To get your text from your clipboard. The main file is a basic keyboard example (enable interrupts, create report, send report, repeat) from the v-usb documentation (not an expert on this library, but as far as I know it works pretty well!) with the three buttons logic. But The Key is a lot more powerful than that. You can do this using something like Pulovers Macro Creator. If they wanted unlimited access to copy and paste from Stack Overflow, all they needed to do was purchase The Key. To copy from the Command Window Select by holding down the left mouse button and dragging the pointer across what you want to copy Once selected, right click To paste at the insertion point, right click again. Every time someone entered the keyboard command to copy characters from Stack Overflow, we showed them a pop-up warning them they were almost out of free copies. It uses the v-usb library (with the proper hardware hooked up to be detected as a low-speed usb device) and three push buttons for the user. To paste whatever is in the Clipboard at the insertion point: Right Click. At the time, officials teased that it would limit the number of times users could copy and paste code from websites, and that developers would need to buy a special keyboard. On April Fool’s Day last year, Stack Overflow announced a keyboard with only Ctrl, C, and V. ![]() Move the cursor to the place where the copied/cut text is to be inserted. Copy M-w or Cut C-w the text from the mark to the current cursor location. This code works with an attiny85 (or probably whatever similar AVR microcontroller once the proper ports, pins, fuses and speeds are changed) and turns the micro into a keyboard with only three buttons: Stack Overflow introduces a new copy/paste keyboard with 'light pollution'. Move to the end of the text to be copied/cut using move-cursor commands. The Stack Overflow April Fool 2021 post was about The Key, a three-keys keyboard that only allows copy and paste operations (classic Stack Overflow joke). Functional implementation for "The Key" (Stack Overflow copy-paste keyboard for April Fool 2021) ![]()
