S0 as server and S1 as client realization problem

Question

There is no problem with S0 and server. All works as expected! But S1 as client won’t work. This code: unsigned char dst_addr[] = {192,168,0,107}; unsigned char dst_port[] = {99,99}; SPI_Write(S1_MR,MR_TCP); //random sending port SPI_Write(S1_PORT,0x12); SPI_Write(S1_PORT + 1,0x12); SPI_Write(S1_CR, CR_CONNECT); SPI_Write(S1_DIPR + 0,dst_addr[0]); SPI_Write(S1_DIPR + 1,dst_addr[1]); SPI_Write(S1_DIPR + 2,dst_addr[2]); SPI_Write(S1_DIPR + 3,dst_addr[3]); _delay_ms(1); SPI_Write(S1_DPORT + 0,dst_port[0]); SPI_Write(S1_DPORT + 1,dst_port[1]); _delay_ms(1); SPI_Write(S1_CR, CR_OPEN); If (SPI_Read(S1_SR) == SOCK_ESTABLISHED) { /////// } When i checked DIPR and DPORT they are not always have correct data. After mcu reset they may have 0 or correct data. What am I doing wrong?

Не правильный код. вот как нужно unsigned char dst_addr[] = {192,168,0,107}; unsigned char dst_port[] = {99,99}; SPI_Write(S1_MR,MR_TCP); //random sending port SPI_Write(S1_PORT,0x12); SPI_Write(S1_PORT + 1,0x12); START: SPI_Write(S1_CR, CR_OPEN); wait(); if(S1_SR != SOCK_INIT) { SPI_Write(S1_CR, CR_CLOSE); goto START; } SPI_Write(S1_DIPR + 0,dst_addr[0]); SPI_Write(S1_DIPR + 1,dst_addr[1]); SPI_Write(S1_DIPR + 2,dst_addr[2]); SPI_Write(S1_DIPR + 3,dst_addr[3]); SPI_Write(S1_DPORT + 0,dst_port[0]); SPI_Write(S1_DPORT + 1,dst_port[1]); _delay_ms(1); SPI_Write(S1_CR, CR_CONNECT); wait(); If (SPI_Read(S1_SR) == SOCK_ESTABLISHED) { /////// } см даташит START: /* sets TCP mode */ Sn_MR = 0x01; /* sets source port number */ Sn_PORT = source_port; /* sets OPEN command */ Sn_CR = OPEN; if (Sn_SR != SOCK_INIT) Sn_CR = CLOSE; goto START; /* Write the value of server_ip, server_port to the Socket n Destination IP Address Register(Sn_DIPR), Socket n Destination Port Register(Sn_DPORT). */ Sn_DIPR = server_ip; Sn_DPORT = server_port; Sn_CR = CONNECT; If (Sn_SR == SOCK_ESTABLISHED) goto ESTABLISHED stage;

Спасибо! Всроде сейчас с регистрами адреса удаленного и портом все нормально… прописываются!
