有没有大佬使用W80X_SDK实现与W5500通信的demo，自己写的一直通信不上。
W801使用的SDK：W80X_SDK_v1.00.10
移植的w5500官方库：https://github.com/Wiznet/ioLibrary_Driver
底层spi gpio初始化的io必须注释掉，如果重复初始化为不同的io可能会通讯异常。
What SDK are you using?
I am currently adapting the W5500 into a w80x-arduino-iot project. Closer to the new year I will publish how to use WizNet chips together with LWIP library.
W80X_SDK_v1.00.10
@JiangXianSen Okay. I'm using this SDK as well
@AnatolSher 请问有测试使用的demo吗
@JiangXianSen No.
I recently ported the uIP stack to HAL 0.0.6. with EnC28J60 support.
http://ask.winnermicro.com/article/209.html
I received the WizNet chips recently and have not started working with them yet. I plan to start the next day or the day after tomorrow
@AnatolSher 好吧，谢谢
通信不上，具体是什么问题，详细描述下，具体到问题点。
There are ambiguities with the SPI bus communication protocol. My colleague tried to control the w5100 chip, but to no avail.
无法通过spi读写W5500寄存器，通过ioLibrary_Driver库简单的配置IP信息，然后再读取，或者直接读取W5500版本信息，都不行。
@JiangXianSen Disable unnecessary subsystems in the SDK
I noticed that the HSPI&LSPI options affect the resulting output. I had to disable them to make the SPI class work properly
@AnatolSher 谢谢，我尝试一下
@JiangXianSen 具体描述下SPI的问题，比如做主做从，模式是否配置对了，pin脚用的那些，错误的现象是什么，是否有尝试用逻辑分析仪做波形，最好有代码。

`这是测试代码
@abcd {{main.c(uploading...)}}
@JiangXianSen wm_main.c里面spi pin脚的初始化注释掉，如楼下截图所示。另外cs如果不想自己控制就调用wm_spi_cs_config初始化就行了，如果想自己控制就调用tls_gpio_cfg初始化，然后用tls_gpio_write来拉高拉低。
@abcd 好的，我试试
