안녕하세요 wiz550io board 를 구매해서 tcp client 로 구현하려 진행중입니다.
사용 mcu 는 stm32f103 이구요…
컴파일러는 KEIL(uVision 4) 을 사용중입니다.
SPI2 를 사용하며 VCC ,GND 및 MOSI,MISO,CLK,SS pin 만 연결되어있습니다.
포럼 내용을 참고하여
sample code 를 구현하여 동작시켜 보니 ip address 는 원하는대로 설정되는것 같으나
AX1 프로그램을 이용하여 TCP Loopback connect 를
시도하니 connect fail 이 나타나고 있습니다.
무엇이 잘못설정되어졌는지 문의드리며 추가적으로 궁금한사항을 몇게 문의드립니다.
아래 참고 1 코드를 활용하여 mcu 구동시
Test PC IP : 192.168.1.3
WIZ550io board : 192.168.1.13 : 5000
PC 와 Wiz550Io board 는 cross cable 로 1:1 연결되어있으며
pc 에서 WIZ550Io 쪽으로 ping 시도시 정상적으로 진행이 됩니다.(응답ok)
wiz_NetInfo gWIZNETINFO 의 내용을 변경하여 board 의 IP 를 변경하고 ping test 를 진행해 보아도 해당 ip로 정상적으로 수정되어
ping test ok 가 되고있습니다.
문 1.
AX1 에서 TCP connect fail 원인이 무엇인가요 코드에 설정하지 않은 잘못되어진 부분이 있나요?
문2.
Wiz550io 는 내부 MAC 을 자체적으로 보유하고 있다고하는데
wiz_NetInfo gWIZNETINFO 를 통해 설정해주는 이유가 무엇인가요? 내부 MAC 을 사용하려면 어떻게 하나요?
문3. DHCP 를 활용하려면 추가적으로 호출해야하는 함수가 무엇인가요?(lib DHCP.C 는 include 완료되어짐)(활용방법문의)
