raspberry pi hack tool

Install a lamp environment for Raspberry Pi in the past two days, but there are too many things installed on it, and the default system space is occupied. But the SD card itself is 16 GB. What if I want to extend the Raspberry Pi to a larger space? I can continue to install the software only after the expansion. After

Requirement Without a network, a keyboard, or a monitor, controlling Raspberry Pi becomes a problem. I accidentally saw an article today.ArticleThat is, you can directly control the Raspberry Pi through the serial port. Give a decisive try. The effect is good. Share it with others!Pai_^ Preparation

0 PrefaceThis article describes how to control the Raspberry Pi gpio port through the file IO sysfs. Control gpio through sysfs, first access the/sys/class/gpio directory, write the gpio number to the export file, so that the operation interface of this gpio is exposed from the kernel space to the user space, gpio operation interfaces include ction and value. Direction controls the gpio direction, while val

to wireless NICs, wireless keyboards, microphones, and audio power supplies. We can divide robot conversations into three parts: listening, thinking, and speaking. "Listen" is to record what people say and convert it into text. "Thinking" means giving different outputs based on different inputs. For example, if the other party says "the current time", you can answer "the current time is Beijing time ". "Speaking" refers to converting text into speech and playing it out. These three parts inv

-J8 option downloads 8 packages in parallel.Note:the Roslisp package are excluded in these generators because the dependency sbcl are not available in the Raspbian rep Ositories. Building SBCL from source may be possible and is not tested. So far, only these variants has been tested on the Raspberry Pi in Indigo; However, more is defined in REP 131such as robot, perception, etc. Just Change the package path

write down what people say, and convert it into words. "Thinking" is to give different outputs based on different inputs. For example, the other person said "now time", you can answer "now is Beijing time xx point xx points." "To say" is to convert the text into speech and play it out. These three parts involve a lot of speech recognition, speech synthesis, artificial intelligence and other technologies, these are to spend a lot of time and effort to study, fortunately, some companies have ope

"1" assumes that Python is used, so you don't have to install SQLite because Python has its own sqlite."2" can be installed using Apt-get. Only the version of SQLite is slightly lower. "3" can be installed using the source code, directly
