Perhaps you have already noticed, when we introduce the software, in the installation of this block generally provide PPA source installation, this is a quick and easy way to install the software, but for some novice, is not very familiar with the PPA, we will introduce in detail below.# Let's take a look at the definition of PPA:
The PPA, known as the Personal package Archives (Personal packages Archive), is a service provided by the Ubuntu Launchp
OpenJDK Java 8 has been made to official Ubuntu repositories for 14.10 Utopic and higher. For Ubuntu 14.04, Ubuntu 12.04, and Linux Mint all users here's how to install it from PPA (Personal pakage Archives) Personal Package Archive It is a service provided by Ubuntu Launchpad website that allows individual users to upload software source code, compile it via Launchpad and publish it as a 2 software package

digitizes the signal of the Electronic Scale load unit. The MSP430 microcontroller can collect the ADS1232 data and drive the LCD display. It decodes user input from the switch and uses a USB to connect to the same optional PC for communication. Figure 6 highlights several key components of the circuit board. The user connects the server load unit to the indicated connector. The Jumper can bypass the optional RC Filter before the input of the ADS1232
device will send an alarm signal, the accurate time and actual temperature of the fault are recorded in the storage unit of fm31256 for system query. At the same time, the event counter of fm31256 is added with 1 count. Similarly, the serial identification area locking function can be used to write the serial number of the electromagnetic casting and rolling power control device into it, which is safe and reliable.3.1 Hardware principlesThe hardware interface circuit 3 of fm31256 is applied to
of the professional manufacturers of microprocessor production. This is a low power, high
Performance: 8-bit, 4-kb flash memory microcontroller. Is a high density non-volatile memory technology and MCS-51TM with industry standards
The Instruction Set and pins are compatible. This is a classic MCU of ATMEL, probably because it is too old to be
Some more powerful siblings are beyond, but this is still the hottest MCU!
Main features and advantages: 1. compatible with MCS-51TM Products

Msp430ware++ 's call method using the 3:modbus module Msp430ware is a set of open source MSP430 hierarchical software architecture based on C + + language, which supports multiple peripherals. This article describes the calling method for the Modbus module driver.

1. PrefaceThese days practice the MSP430 ADC12 function, although the on-chip ad function is relatively simple but also learned a little "doorway", this "doorway" is the difference between msp430f5438a and msp430f5438. Here is an example of the use of the on-chip ADC, the first implementation of the UART and timer 1S overflow function, on the basis of the above functions of each 1S printing ad conversion results, the conversion channel directed to cha

Zimmerman said: "Mumble is like an IRC that supports speech. You can set a group of channels where Team members can access different channels to find people to communicate with. They can freely access these channels, just like entering and leaving the room ".
Engineering organizations usually like to share ideas on whiteboards, And the Ubuntu team is no exception. Although Canonical employees and Ubuntu contributors are scattered in the field, but Zimmerman says many things are done by sharing

It has been one month since the last version 0.4.7.3 was released. Now, UbuntuTweak0.4.8 has been released again. In addition to updating third-party sources, the dependency detection mechanism is also improved. --Launchpad.net's PPA source has become a good place for many Ubuntu users to experience fresh software, and more software is sending their updated versions to Launchpad. However, it is still a lot of trouble for users to add PPA sources by th
I 've been using MAC for a long time, but I don't know a lot about it. I find that I am not good at discovering new things, and I do not like to use new things. A Senior sister in the lab downstairs also bought a Mac pro, but she received a 20 thousand scholarship. The elder sister is not very clear about the operations on the command line and will often ask me. Then there will always be issues that I cannot solve each time. I have never encountered some problems, so I had to use Baidu. People
