W5100, STM32F103VC and SPI1 problem


#1

Hi All,

I have an issue using SPI1 on the STM with the W5100.

Before , i connected the W5100 to SPI2 and all worked fine.

Now ,i connect to SPI1 and there is a problem (I write 0x31 to address 0x009 and read 0x60)

[There is no other dvice on this SPI bus!!]

What can be the problem , i changed all the pins to SPI1 all look good in the scop

Please help with this issue.

Thanks a lot

Hi, etay014.

I think problem is MCU or code.
Because SPI2 works fine. It means W5100 receives and sends well.

Let me know your setting code and let’s discuss.

Best regards.
