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
