SPI interface

Hi
To put the sck to logic 1 or 0 do i use the congfigure wizard to set it or i have to write the source code for it? And what is CKPOL and CKPHA are they just logic 1 or 0 setting? And do anyone try or how to use the the C8051F120DX SPI interface to connect the SPI interface of the nRF24L01? tks

Re: SPI interface

Hi Alkid,
Can you be more specific about the configuration wizard?
About CKPOL and CKPHA, I can tell you about this. CKPOL stands for clock polarity and used to identify the positive or negative edge. CKPHA stands for clock phase and denotes whether there will be a half clock time delay when the signal traverse on the SPI lines.

The Configuration Wizard 2 utility helps accelerate development by automatically generating initialization source code to configure and enable the on-chip resources needed by most design projects. In just a few steps, the wizard creates complete startup code for a specific Silicon Laboratories MCU.
