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

0. PrefaceThis blog post may not have much use value. But practice for practice. There are many ways to use SQLite on Raspberry Pi, and there are many ways to install it. "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

We have explained in detail the Raspberry Pi control ultrasonic module ranging (http://www.cnblogs.com/yuemo/p/8888342.html) and ultrasonic control buzzer module audible (http://www.cnblogs.com/ yuemo/p/8906111.html).Today we'll see how to apply all two modules and make an anti-theft device.First look at the connection of each pin (requires seven mother-to-female DuPont line):Ultrasonic module:1.VCC: Connec

Do you have an idle mobile hard drive or Raspberry Pi? You can use these to create a cheap and low-energy NAS. The final effect is definitely not as good as the NAS for $500, such as those produced by Synology DiskStation. But you can build a low-energy network storage platform-and especially suitable for those who are tired of the National Security Agency's data monitoring, you can store the data in this "

0. PrefaceWhy do you want to use cross-compilation for "1" The speed at which the cross-compilation tool is developed faster. The Raspberry Pi has already installed the GCC toolchain, which can be compiled directly from the Raspberry Pi source code to generate the executable file. At the same time, the PC can also use

Is Raspberry Pi able to use the serial port? The answer is yes. The specific method is as follows: 1.

Note that the TX of

there are two i²c devices connected to the bus, and their addresses are 0x48 and 0x77 respectively. If you do not see a device, check the hardware connection, and remember to open the system config inside the i²c.Then still the sample code: Import time Import SMBus addr=0x48 cmd=0xab # open/dviev/i2c-1 bus = SMBus. SMBus (1) # Read and write data, Case 1 Data = bus.read_byte (addr) bus.write_byte (addr, data+1) # Read and write data, Case 2 = Bus.
