w6100 evb code

Question

Can’t get example code to function. According my logic analyzer, SPI seems to not be working properly. Getting all zeroes when running register dump and getnetinfo. I’m running Keil V5. Tried the stmcube example with no joy as well. I’ve included my project code. Thanks, edtpcecDay3Codefred.zip (18.0 KB)

Hi, edtp. I think you set just one byte read and write functions like this. “reg_wizchip_spi_cbfunc(spi_rb, spi_wb,0,0);” wiznet spi interface supports burst read and write. In the getnetinfo function, many functions use burst read/write like WIZCHIP_READ_BUF/ WIZCHIP_WRITE_BUF. You must set this function, too. Thanks.

Hello edtp, Please refer to this attached zip file (W6100 Loopback Keil Project). And you can find the W6100 EVB example on this repository: WIZnet ioLibrary & io6Library examples · GitHub. 20191010_W6100EVB_loopback_Hal.zip (2.8 MB)

자체 해결했습니다… HAL 사용자중에 저와같은 경우가 있을것 같아 기록으로 남깁니다… STMCube로 Truestudio HAL Driver를 사용하는것으로 설정하면. . . . . MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); MX_IWDG_Init(); MX_RTC_Init(); MX_SPI1_Init(); MX_SPI2_Init(); MX_TIM4_Init(); MX_USART1_UART_Init(); MX_USART2_UART_Init(); MX_USART6_UART_Init(); 이런식으로 메인함수에서 여러 설정과 함께 SPI가 먼저 선언됩니다. 20191010_W6100EVB_loopback_Hal.zip에서 설명한대로 spi_set_func(&hspi2); BoardInitialze(); ctlwizchip(CW_SYS_UNLOCK,& syslock); ctlnetwork(CN_SET_NETINFO,&gWIZNETINFO); printf(“VERSION(%x) = %.2x 
”, VER,getVER()); print_network_information(); 위와 같이 그대로 따라 했으면 되었을텐데 SPI가 먼저 선언되는 바람에 BoardInitialze();에서 spiInitailize();를 생략했기 때문이었습니다… 아래와 같이 정리를 하니 예제에 나와있는것 같이 잘 초기화가 진행되었습니다. spi_set_func(&hspi1); MX_SPI1_Init(); //먼저있던 SPI1을 이부분에서 선언… W6100Initialze(); ctlwizchip(CW_SYS_UNLOCK,& syslock); ctlnetwork(CN_SET_NETINFO,&gWIZNETINFO); printf(“Register value after W6100 initialize!
”); printf(“VERSION(%x) = %.2x 
”, VER,getVER()); print_network_information(); 그대로 따라했으면 되었을것을 괜힌 HAL을 탓했습니다…
