Hello world

1. SnapEDA - http://www.snapeda.com

SnapEDA 는

3D 모델과 2D Footprint, 회로 Symbol 까지도 다운 가능하다.

3D 모델은 step 파일로 다운 받을 수 있고,

Footprint와 Symbol은 대부분의 전자캐드 Tool 형식에 맞춰 제공한다.

로그인 필요.

2. Ultra Librarian - http://www.ultralibrarian.com

Ultra Librarian 은 SnapEDA 처럼

3D 모델과 2D Footprint, 회로 Symbol 을 다운 받을 수 있다.

3D 모델은 step파일로 다운 받을 수 있고,

Footprint와 Symbol은 대부분의 전자캐드 Tool 형식에 맞춰 제공한다.

로그인 필요.

3. TraceParts - http://www.traceparts.com

TraceParts는 전자부품 Symbol, Footprint 부터 3D, 2D 도면까지 제공한다.

전자부품, 기계부품, 기타 여러가지 가리지 않고 도면을 제공한다.

다운받기 위해서 로그인 필요.

4. 3D CONTENTCETRAL - http://www.3dcontentcentral.com

3D CONTENTCETRAL 은

각종 전자부품을 3D 또는 2D 로 다운 가능하다. Footprint와 Symbol은 제공하지 않는다.

전자부품도 많긴 하지만 기구설계 관련 파일이 많다.

3D는 step 외 여러가지 포맷으로 받을 수 있고,

2D는 dxf, dwg 외 여러가지 포맷들로 받을 수 있다.

로그인 필요.

5. 각 부품 제조사 홈페이지

규모가 있는 제조사는 자사 부품을 3D 모델로도 다운 받을 수 있게 해놨다.

6. 마우저(Mouser), 디지키(Digikey) 전자부품 쇼핑몰

쇼핑몰에 들어가 부품을 검색하고 세부항목란에 가면

마우저는 SmacSys라는 곳과 연동하여 부품 Symbol, Footprint, 3D model을 다운 받을 수 있게 했다.

디지키는 Ultra Librarian에 연동하여 다운 받을 수 있게 했다.

2. Wifi360 module AT command

AT

1. WiFi Station mode 설정

AT+CWMODE_CUR=1 //Station mode 로 설정한다. AT+CWMODE_DEF 의 경우 flash 에
저장된다.

==> OK

2. Single Connection mode 설정

AT+CIPMUX=0

==> OK

3. DHCP enable 설정

AT+CWDHCP_CUR=1,1 //Station mode 에서 DHCP enable

==> OK

4. 연결가능한 WiFi AP List 확인

AT+CWLAP

==> +CWLAP:(3,"ssid",-57,"mac address",1,1) //encryption method, ssid, rssi, mac address, channel, wps

5. WiFi AP 에 연결

AT+CWJAP_CUR="ssid","password"

==> WIFI CONNECTED
WIFI GOT IP
OK

6. WizFi360 device 의 IP address 확인

AT+CIPSTA_CUR?

==> +CIPSTA_CUR:ip:"192.168.10.13"

7. WizFi360 이 연결되어 있는 AP 와 같은 AP 에 연결된 PC 에서 TCP Server Open.
- Ex) IP : 192.168.10.100 Port : 5000

8. WizFi360 connects to the TCP Server as a TCP Client

AT+CIPSTART="TCP","192.168.10.100",5000 //protocol, server IP, port

==> CONNECT
OK

9. WizFi360 sends data to the TCP Server

AT+CIPSEND=10 //data length(10 byte) 설정

==> OK
> //WizFi360 에서 serial data 의 수신을 시작하기위해 >를 return 한다.

1234567890 //data 를 입력한다.

==> Recv 10 bytes
SEND OK

10. When WizFi360 received data from TCP Server, it will prompt message below:

==> +IPD,10:1234567890

11. End the TCP Connection
