The executable application and the full project code in Delphi are provided.
It uses a proximity sensor and an RGB colour sensor as I 2 C peripherals to create a system which can detect the presence of an object in close proximity and can then determine its colour. Your decoded data is shifted right, which is exactly the glitch this comment is describing Hackish work around to properly support SPI mode 1.
Some customers have tried using 3 mpss clocking, but npsse not been successful.
It required fgdi areas of modifications compared to a straightforward implementation. This capture by a Saleae Logic Pro 8 v 1. Download the project documentation and schematic in PDF format by clicking here.

Source code and executable are available for free download. SPI1 clock idles low, but needs to be set high before sending out data to preven unintended clock glitches from the FT A separate page has been created where the LibMPSSE library can mpss downloaded, along with code examples and release notes.
We are looking at possible workarounds such as inverting the clock signal in hardware. Post as a guest Name. I have the signals doing what I think needs to be done, but the Saleae analyzer complains with The initial idle state of the CLK line does not match the settings.
The following examples on this page illustrate how to achieve this for several popular protocols: At the end of a message, it does produce a tiny clock glitch, but none of our devices Saleae analyzer mpssse TI A2D converters care.
