SPI interface network port problem

SPI interface network port problem [Copy link]

 

I originally bought an SPI interface network port module, which I used frequently and published reviews for.

But today I found that many of the good programs are no longer usable.

What is going on? Is the network port broken?

Changing the computer doesn't work and the puzzle still doesn't work.

I found out that he probably died here.

	W5500_Hardware_Reset();	

void W5500_Hardware_Reset(void)
{
	GPIO_ResetBits(W5500_RST_PORT, W5500_RST);//复位引脚拉低
	Delay(50);
	GPIO_SetBits(W5500_RST_PORT, W5500_RST);//复位引脚拉高
	Delay(200);
	while((Read_W5500_1Byte(PHYCFGR)&LINK)==0);//等待以太网连接完成
}

While statement there.

And the reading and writing registers are not correct either.

Could you please tell me where I might have gone wrong? Thanks!

I changed a computer and still couldn't figure it out.

There might be a communication port failure.

Is it a bad contact?

I tested the lines and they are all connected.

Thank you! You mean the communication port of the network port module is faulty.

This question is so strange~

Can the speed of SPI meet the requirements of the network port?

If the network card of the board is not rusty, you should still consider more problems with wiring and code.

The code should be fine, it was working fine before. I also tested the wiring, it's all connected.

I think it is probably broken. However, the network port light is flashing. But the spelling is not working, and the read and write registers are not correct.

If the wiring or power supply is not connected incorrectly, it will not be damaged so easily. You should first think carefully about the differences in operation and environment between the current and past uses.

Thank you, Chunyang! I will try again. However, there should be a difference in the environment, but it doesn't seem to have much impact.

The "environment" here refers to the upper hardware platform, cables, power supply, software code, software compilation and operating environment, etc. Please check them one by one.

Thanks Chunyang. I tried a program yesterday and found that it actually worked. It's really strange, but it seems to work sometimes and sometimes not.
