The first phase rather let me down, I was too dishes, I did not want to talk about all speak out. Often write a lot, and then little by little, delete, and finally no how much.
And it feels difficulty inappropriate, in a very awkward position. Put it simple, the difficulty threw library, the library is not open source. Job title is actually a group of rare, I have almost never do.
Look down on those books before speaking knowledge of the dead, and now understand that the knowledge of living too difficult to write. In particular microcontroller side, knowledge already complicated and difficult to organize.
Had wanted to speak slowly behind the circuit, bus, interruption, but a feel tired, and second, that can not speak, so he changed the plan.
Currently there are 6 of the second tentative say:
Timer interrupts: interrupt basis, timer mode, digital automatic scanning;
UART Zatan: bus interrupt, send and receive buffers, multiplexers sent;
Matrix keyboard: SPI bus, 74HC595,74HC165;
DAC music: PC program, onboard DAC, an analog circuit;
Oscilloscope: OLED screen, transplantation third-party libraries, use EEPROM;
To top: RTOS, C ++ tools, event-driven architecture.
AVR microcontroller tutorial on here. Winter is expected to finish, go back and learn the language of the finish. I really need to learn the language.
If after a few years I still remember when I was little done this thing, I'll put it another microcontroller to re-write a good tutorial.
