![]() Here's what it sounds like saying, "hello world" 20101215_164333.mp3 I mentioned the laser and used it here, but I have other plans. Here is the source code for the Java app. I wanted to visually display the camera's tracking data, so I wrote a Java Swing equivalent of the CC2's ATM 18 Project BlobTracker Front End software, since I couldn't get it to work. The output from the microcontroller is a comma-separated list of x-y pairs: x1,y1,x2,y2,x3,圓,x4,y4 The camera tracks four light sources and provides x and y coordinates. Here some sample output over the USB serial device while the camera tracks a laser. The source code listing can be found here. I converted kako's source code to mbed C++ and added the ~20MHz clock signal on p21, and setup I2C communication on p9/p10. So far I've gotten away with omitting the cap. In kako's and others' schematics, there's a 0.1uF capacitor between RESET and GND, probably to filter glitches. Note the pullup resistors on SCL, SDA, and RESET. I soldered the camera's 8 thin leads onto a 2x4 pin header and soldered that onto a perfboard with 1x4 headers on either side so I could easily breadboard the thing. Here are the sources for the Wiimote IR Camera hacks:Īfter disassembling the Wiimote, I desoldered the camera using solder braid with some extra flux paste. I'm following in the footsteps of great hackers, here. To move to insert mode, press i.The Wiimote I planned to hack was purchased with a most generous gift card from my father in law (thanks, Mike!) Inside the Wiimote is an infrared camera that tracks infrared light point sources and reports their coordinates over I☬. On the other hand, the insert mode enables you to type and add text into the file. To switch to command mode, use the Esc key. By default, Vim launches in command mode, allowing you to move around and edit the file. Some of these commands switch between command and insert mode. Esc – exit insert mode switch to command mode.ea – insert text at the end of the word.O – open a new line above the current one.o – open a new line below the current one. ![]() a – switch to insert mode after the cursor.I – insert text at the beginning of the line.i – switch to insert mode before the cursor.L – move to the bottom of the screen (L=low).M – move to the middle of the screen (M=middle).H – move to the top of the screen (H=high).Ctrl + i – move forward through the jump history.Ctrl + o – move backward through the jump history.Ctrl + y – move screen up one line (without moving the cursor).Ctrl + e – move screen down one line (without moving the cursor).Ctrl + f – move forward one full screen.The following commands are used as a quick way to move within the text without scrolling. On the other hand, in the third bullet, the ^ key moves the cursor to the hyphen (the first character in the line). In the first bullet, the command moves the cursor to the blank space before the bullet. To illustrate the difference between 0 and ^, take a look at the following example. #G / #gg / :# – move to a specified line number (replace # with the line number).^ – jump to the first (non-blank) character of the line.0 (zero) – jump to the beginning of the line.However, if you use B, the cursor moves all the way back to: “ step-by-step” since there is no whitespace between these characters. The first time you press b, the cursor moves back to “step-by- step”. W – move to the start of the next tokenįor instance, you have the noun phrase “step-by-step” as part of a text and the cursor is placed at the end of it.For example, if you run 5j the cursor moves down 5 lines. You can also use these keys with a number as a prefix to move in a specified direction multiple times. The basic keys for moving the cursor by one character are: On the other hand, a token is anything separated by whitespace and can include punctuation.Īdditionally, you can move to different parts of a text by screen view. You can move the cursor within a file by single characters, words, tokens, or lines.Īccording to Vim, a word can be a group of letters, numbers, and underscores.
