Issue about SPI

Hi everyone,

 

I'm using the MCF51QE128 processor in a proyect and I'm facing the following problem. When I communicate with a SPI slave, I have to wait for at least 800 microseconds before I can read de slave answer from the input buffer. Otherwise, the values I read from de buffer are dirty. The SPI in the processor is configured in a bean, I only write and read the buffer, the answers fron the slave are as expected, but it's this delay issue I would like to improve.

 

Anyone?

Thanks,

Nicolas
