Confusion and internal injury

Recently has been to their own life feeling confused and frustrated, from the big Spring semester began to work in Beijing, more than a year, now feel that they do not, in the company has been the application of 51 single-chip microcomputer to achieve such as LED, infrared remote control, there are some other simple features, now think about is very sad, For almost two years, I have been on the level of entry.

has been complaining about the company's low technical content, the original real technical low is their own, because I am a person responsible for the company these electronic equipment, the gold content does not have their own reasons, previously felt that their own development of new things in the company's position basically will not use, and I take the company's support to improve themselves, feel not very suitable. Own private to do, and need to do their own development environment, such as I want to 51 single-chip computer and DM9000 communication, draw a PCB to make a hundreds of, but also not necessarily can communicate, I was just graduated rookie, DM9000 the difference wire wiring is not sure, if the cabling is successful, The agreement for me this rookie is a big difficulty, is finally overcome all kinds of difficulties, do out of things and use, so do not fight and back, has been in accordance with the company's requirements to do.

Now think of the original oneself silly, flinched for more than a year, so that now own a sense of nothing. No one in the company understand the electronic technology, so they always from I can do the scope and the actual needs to design, and I think the company has been in accordance with the requirements to apply, their own silly, with the idea but because of all kinds of difficulties to retreat, the result not only himself has not improved, the company's electronic design capabilities have been in place.

From the company received a project with mobile phone control electronics, electrical appliances, multimedia equipment also includes computers, the project is a package for acquaintances to do, I participate in the whole process, with the ARM9 Development Board s3c2440. Although I am involved in the project, but only the periphery. Look at the realization of the project, the envy of Daniel, the technical content is high AH. Microcontroller still do not understand I like linux,android, because I found that these prospects are very good, and the application of a wide range of more than single-chip computer, the most close to people's lives, more important is very interesting. So began to Linux,android,c++,java study, and later learned to encounter a lot of problems, a person groping too difficult, the more learning the more unfathomable, inside the things are difficult to understand every kind of, do not understand the words and feel not practical, make a mess, confused.

Later realized that can not eat a fat, start from Linux, on the Internet to find information, familiar with the embedded Linux system and development environment, mastered the shell, GCC, VI and GDB debugging some knowledge, many people recommend to buy a development board, So I bought CORTEX-A9 's Tiny4412, considering that after learning Linux you can also use it to learn Android. Bought after the tutorial began to learn, the more confused, a lot of people do not know why, is only the mechanical follow the tutorial, and is the bare metal development, and I think not the same, see the chip data in English, but also depressed desperate, it seems novice really not suitable for this development board. So recently I began to learn from the basics, English must be understood to continue to look back at Tiny4412 chip data, "Linux programming", "Linux Program Guide" "UNIX Environment Advanced Programming" ....

Graduation nearly two years of time, I have done what, I do not know, I know nothing.
