witam,

czy ktos korzystal z tego cuda? Udalo mi sie uruchomic to to przez SPI, otwieram socket (TCP), robie connect, send, disconnect i niestety nie moge tej operacji powtorzyc. Zwisa mi na send, ale tak naprawde rzecz w tym, ze bez software'owego resetu uklad na drugie polecenie connect nie posyla nic w siec Ethernet. Podczas pierwszego polaczenia dziala ksiazkowo (SYN,ACK,FIN). Testowalem juz rozne kombinacje rejestrow robiac ich zrzuty - jak dotad nic nie moglo. Uklad utyka w grafie stanow na SYNSEND (cos go blokuje chyba wewnetrznie, ze nic nie posyla) i stad dalsze proby koncza sie niepowodzeniem. Korzystam z modulu WIZ810MJ i sprawdzalem efekt juz na dwoch - powtarzalne. Taiwanczycy nie odpisuja pomimo, ze poslalem im zrzuty rejestrow ukladu w roznych stanach :/

pozdrawiam Janusz U.

P.S. Nie oczekuje odpowiedzi typu uzyj Ethernuta czy lwIP, bo nie w tym rzecz. Jak nie odpale tego to tak postapie, bo doswiadczenie z nimi mam (glownie lwIP).

Czy na pewno przed każdym połączeniem otwierasz gniazdko?

I try to implement TCP client (HTTP exactly) using W5100 chip. I do (using functions from w5100.c/h and socket.c/h like for PIC24 demo):

INITIALIZATION

----------------------- iinchip_init(); // SW reset setSHAR(SHAR); sysinit(0x55/*2K*/, 0x55/*2K*/);

// DHCP before? setGAR(GAR); setSUBR(SUBR); setSIPR(IPR);

LOOP

---------- wait 0.5s socket(s, Sn_MR_TCP, 0/*source port: temporary*/, 0/*flags: none*/) connect(s, (uint8*)&iptl, 80) send(s, dd, sizeof(dd)-1) getSn_RX_RSR(s) recv(s, &b, sizeof(b)) recv(s, &b, sizeof(b)) disconnect(s)

My problem: W5100 halts on send() in second loop. What is the problem?!

best regards Janusz Uzycki
