[rcluze]

Hello,

I tried to use the example of SPI slave with the sdk 10.0. But I have an issue: the character "Ignored Transaction" is send on MISO pin.

I would like to now why these does not work?

In advance, thank you.

My SPI master is an STM32 and yes I have seen this thread but it didn't help me. In my case, the callback function is never called and I don't undertstand why. The SPI clock is 83KHz. I have a delay between the CSN selection and the transmition of 1ms.
