Arrangement of Terms (Updated 01-16-2018)

1. Compile

Act of turning human-readable code into the machine-understandable code.

 

2. Debug (=get rid of bugs)

Act of finding where the application is going wrong in the code.

 

3. UART (Universal Asynchronous Receiver/Transmitter) (범용 비동기 시리얼통신)

1) Serial(직렬) Communication

2) The method that transmits the data every certain period sequentially.

(데이터를 특정시간 간격으로 순차적으로 보내는 통신 방법)

(병렬통신: 한 번에 한 의미의 데이터를 보내는 통신 방법)

(장점: 병렬 통신보다 선을 적게 사용한다)

3) The communication that does not need synchronous signals.

-> Therefore, the protocol has to be set up.

* Protocol: 컴퓨터 간에 정보를 주고 받을 때 통신방법에 대한 규칙과 약속(어떻게 통신을 하겠다)

  4) UART has “start bit” and “stop bit” that tell the other computer whether it’s started or stopped.

  5) The speed of communication [bps/sec]

Ex) Data bit: 8 bit / Speed: 1 bps

-> It will last for 8 secs and end with “stop bit”.

(1초 간격으로 1비트씩 8초가 걸려 데이터가 전송되고 정지비트로 끝난다)

 

4. JTAG (Joint Test Action Group)

1) To test if PCB or IC devices which are built work well

2) The usage of JTAG is similar to USB Port

-> However, because the speed of communication is highly slow, it is used mostly for check if devices work fine.
