We have tested the SPI example code provided from ST disco board with other boards like atmel controller.
Atmel as master and ST disco board as slave.
We have connected
We have set both board side clock frequency 86khz,
Clock Polarity 0
Clock phase 0
SPI Slave(ST) written data to master(Atmel) is below
we have observed the data as below table, other data we have attached.
Data Binary LSB/MSB No of bit shift
0x20(Real) 0010 0000 - -
0x10 0001 0000 LSB 1 bit shift on right
0x80 1000 0000 MSB 2 bit shift on left
When we made slave(ST)side LSB or MSB orientation data shift is happening as above,
Can you please suggest me what is the issue.
the other data observed is attached.
