From beginner to qualified wireless engineer

So what gaps do you need to cross from beginner to engineer?

First of all, you need to have a solid foundation of electronic knowledge, such as from the basic principles of simple microcontrollers such as 8051 to using software to realize product functions, from simple device principles to designing product PCB diagrams.

Secondly, you need to have strong hands-on skills, including writing code, debugging software and hardware , designing circuit boards, etc.

Furthermore, you need to have a background in wireless / RF knowledge;

The general learning process for beginners is:

First, buy a book on 8051 programming and learn;

Then buy a development board and practice Keil C on it ;

Then buy an emulator and learn how to debug programs on it.

This learning process has two big drawbacks:

  First, these things come from different places from books to development systems, and there is no coherence. Second, there is no direct connection with wireless communication and high-frequency circuits.

The wireless learning package developed by Chengdu Wireless Dragon Communication Company (www.C51RF.com) ( including one C51RF-4N or 4C simulator , two reference design modules ( NRF9E5 /NRF24E1/CC1010 optional) , supporting software, standard example programs, and a book " Introduction and Practice of Wireless Communication and Wireless Networks " ) overcomes the above shortcomings and is very suitable for students, electronics enthusiasts, and beginners .

The wireless learning and development system is not only a standard 8051 development system, which includes all the resources needed for single-chip microcomputer development, but also has the basic resources for wireless learning. Since the software / hardware and teaching materials are designed and developed by the same company, it has the characteristics of strong pertinence, easy to understand and convenient to use.

C51RF-4N/4C is a very easy-to-use wireless microcontroller development system. It only needs a serial port to connect to a PC , and can perform program downloads, online simulation runs, single-step, breakpoints, etc. in the KEIL development environment. At the same time, it is specially designed for the special requirements of high-frequency design, which can ensure that the development system does not interfere with the high-frequency part of the wireless microcontroller when it is working, and ensure software tracking and hardware debugging in a real-time high-frequency communication environment.

<< Introduction and Practice of Wireless Communication and Wireless Network >> will teach you to build a wireless development platform by yourself, from point-to-point, point-to-multipoint, to mesh wireless network, ( interspersed with the introduction of key technologies of related wireless communication and wireless network, such as FDMA/TDMA/CSMA/FHSS , etc. ) step by step. It allows electronic engineers who are completely unfamiliar with wireless communication and wireless network to easily get started, experience the principles of wireless communication, and understand the secrets of wireless network. When you have completed all these experiments, you may be greatly relieved that "wireless communication and wireless network are so simple and easy"; another major feature of this book is that it successfully transforms the complex principles of wireless communication and wireless network into a pure software development process. Everything becomes a source program written in C51 . You only need to change the relevant program code to easily become familiar with the wireless communication and wireless network functions you need; engineers from Chengdu Wireless Dragon Communication Technology Co., Ltd. developed the C51 source code for all the experiments in this book, and have undergone comprehensive actual wireless communication and network tests on relevant wireless modules. Readers can make any modifications they like on these source codes and add any possible applications of their own.
