W5200 atmega128 과 SPI 통신실패

Question

아래의 코드로 16MHz ATMEGA128과 Wiz5200을 연결 했습니다. MAC Address를 확인하면 초기화 되어있지 않습니다. 단 연결확인위해 5100에서 사용한 아래의 코드를 넣으면 5200으로부터 더미 데이터는 올라옵니다. 수정할 사항 확인 부탁 드립니다. 아래를 오픈하고 실행시 IINCHIP_SpiSendData(0x0F); //used by 5100 MAC ADDRESS : 00.08.dc.11.22.26 G/W IP ADDRESS : 192.168.10.1 SUBNET MASK : 255.255.255.0 LOCAL IP ADDRESS : 192.168.10.50 AVR :TCP SERVER, PORT : 5000 W5200 SPI mode Net Config Information MAC ADDRESS : 20.56.c5.a6.80.62 G/W IP ADDRESS : 24.65.33.50 SUBNET MASK : 89.110.20.8 LOCAL IP ADDRESS : 25.64.146.131 AVR :TCP SERVER, PORT : 5000 아래를 막고하고 실행시 //IINCHIP_SpiSendData(0x0F); //used by 5100 ====================== MAC ADDRESS : 00.08.dc.11.22.26 G/W IP ADDRESS : 192.168.10.1 SUBNET MASK : 255.255.255.0 LOCAL IP ADDRESS : 192.168.10.50 AVR :TCP SERVER, PORT : 5000 a3 W5200 SPI mode Net Config Information MAC ADDRESS : 00.00.00.00.00.00 G/W IP ADDRESS : 0.0.0.0 SUBNET MASK : 0.0.0.0 LOCAL IP ADDRESS : 0.0.0.0 AVR :TCP SERVER, PORT : 5000 소스코드 참고: // PB3(MISO), PB2(MOSI), PB1(SCK), PB0(/SS) // CS=1, waiting for SPI start // SPI mode 0, 4MHz #define SPI0_Init0() DDRB |= SPI0_SS_BIT|SPI0_SCLK_BIT|SPI0_MOSI_BIT; PORTB = 0x01; SPCR = 0x50; SPSR = 0x01; #define IINCHIP_SpiInit SPI0_Init0 uint8 IINCHIP_WRITE(uint16 addr,uint8 data) { IINCHIP_ISR_DISABLE(); // Interrupt Service Routine Disable //SPI MODE I/F IINCHIP_CSoff(); // CS=0, SPI start // IINCHIP_SpiSendData(0x0F); //used by 5100 IINCHIP_SpiSendData((addr & 0xFF00) >> 8); // Address byte 1 IINCHIP_SpiSendData(addr & 0x00FF); // Address byte 2 IINCHIP_SpiSendData(0x80); // Data write command and Write data length 1 IINCHIP_SpiSendData(0x01); // Write data length 2 IINCHIP_SpiSendData(data); // Data write (write 1byte data) IINCHIP_CSon(); // CS=1, SPI end IINCHIP_ISR_ENABLE(); // Interrupt Service Routine Enable return 1; } /** @brief This function reads the value from W5200 registers. */ uint8 IINCHIP_READ(uint16 addr) { uint8 data; IINCHIP_ISR_DISABLE(); // Interrupt Service Routine Disable IINCHIP_CSoff(); // CS=0, SPI start // IINCHIP_SpiSendData(0x0F); //used by 5100 IINCHIP_SpiSendData((addr & 0xFF00) >> 8); // Address byte 1 IINCHIP_SpiSendData(addr & 0x00FF); // Address byte 2 IINCHIP_SpiSendData(0x00); // Data read command and Read data length 1 IINCHIP_SpiSendData(0x01); // Read data length 2 IINCHIP_SpiSendData(0x00); // Data read (read 1byte data) data = SPI0_RxData(); IINCHIP_CSon(); // CS=1, SPI end IINCHIP_ISR_ENABLE(); // Interrupt Service Routine Enable return data; } main() { IINCHIP_SpiInit(); IINCHIP_WRITE(MR, MR_RST); wait_1ms(100); printf_P("
