汇编语言 Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS
Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switching the port on or ...
单片机 A FLASH Bootloader for PIC16 and PIC18 Devices
Among the many features built into Microchip’sEnhanced FLASH Microcontroller devices is the capability of the program memory to self-program. This very useful feature has been deliberately included to give the user the ability to perform bootloading operations.Devices like the PIC18F452 are designe ...

书籍 Fundamentals_of_Global_Positioning_System3
If one examines the current literature on GPS receiver design, most of it is quite a
bit above the level of the novice. It is taken for granted that the reader is already at a
fairly high level of understanding and proceeds from there. This text will be an
attempt to take the reader through the conc ...

This R2.9 revision of the CLID detector provides the TYPE 1 (on-hook, between first and second ring, or
before first ring) signal detection and returns the message raw byte data without parsing of particular fields
such as Message Type, Parameter(s) Type(s), etc. The decoding of the message meaning ...

Summary
Many control applications require converting some analog input to a digital format. The ADCINC12 User
Module is a general-purpose, 12-bit analog to digital converter (ADC) that does just that. This Application
Note is meant to be a simple introduction into its operation. The steps required t ...

The main purpose of this project is to add a new scheduling algorithm to GeekOS and to implement a simple synchronization primitive (semaphore). As you might have already noticed, GeekOS uses a simple priority based preemptive Round Robin algorithm. In this project, you will change this to a multile ...

After an introduction to the history of mobile communications, this guide considers the basics of mobile radio, the design of cellular and private radio systems, and issues of interworking with the fixed network. It then looks at the role of the mobile radio operator, the design and operation of mob ...
