Hello, guys!

   recently, I made a test demo project. I use my LPC824 as master and LPC 1114 as slave. This system work well in SPI mode 1&3, but in SPI mode 0&2, the slave just receive the first byte of each frame, and sometimes this byte left shift 1 bit.

I dont know why, maybe my configs is wrong. So, I download the official demo lpcopen_v2_00a_keil_iar_nxp_lpcxpresso_, and use it to test. In SSP demo, I change the config to SLAVE, but it work the same as what I coding.


   guys! I need your help!


best wishes!
