Thank all!
I have confirm the pin function after reading yours comment and data sheet. The master should be fixed. moreover, i have one more problem. 1. select a uP as a slave, 2. I write the data to spi data register in slave uP. 3. When the master access the slave, then slave will shift out the spi data register at the same time. is the above sequence correct? |
