Title: FT4222H SPI mode 3
Post by: mcarrier on November 10, 2017, 08:30:58 PM

Hello all,
Has anyone used the FT4222H device in SPI mode 3??? I am having quite a bit of an issue talking to a broadcom Eswitch device which runs in spi mode 3. It appears that the FT4222 reading of the MISO line might be wonky. Anyway, just wondering if anyone else has used this device.

Hello,

Are you using the device and an SPI master or slave?

You could refer to the software examples as part of the LibFT4222 (http://www.ftdichip.com/Products/ICs/FT4222H.html) download:

.\LibFT4222-v1.4\samples\

There is also UMFT4222EV (http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm#UMFT4222EV) available for test and development.
