The following examples on this page illustrate how to achieve this for several popular protocols: Some customers have tried using 3 phase clocking, but have not been successful. The software is changed with adding slightly odd but careful ordering of chip select and clock transitions. Home Questions Tags Users Unanswered. We got it working.

At the end of a message, it does produce a tiny clock glitch, but none of our devices Saleae analyzer and TI A2D converters care.

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.

A separate page has been created where the LibMPSSE library can be downloaded, along with code examples and release notes. The following examples on this page illustrate how to achieve this for several popular protocols: Both digital and analog versions of each SPI line are shown for thoroughness.

LibMPSSE-SPI Examples

SPI1 clock idles low, but needs to be set high before sending out data to preven unintended clock glitches from the FT TI have a JTAG learning tool and accompanying abstract available mpsxe their website which is available for free download.

That appears to definitively answer the question of how to do this. Unfortunately it is interpreted and shown as 0x40 0x Your decoded data is shifted right, which mpswe exactly the glitch this comment is describing.

According to this library, you need to set the clock high before enabling the slave select line, otherwise it creates a clock glitch. I am not sure what to make of the situation. Hackish work around to properly support SPI mode 1.
