This EE-Note describes how to connect video devices such as the Micron® CMOS Image Sensor to the parallel peripheral interface (PPI) of Blackfin® processors. The PPI serves as a video interface to a host of CMOS sensors and video encoders and decoders. The system was tested on the ADSP-BF561 processor. Nevertheless, as the PPI interface of all Blackfin derivatives is fully compatible, this EE-Note applies.
This Engineer-to-Engineer Note details the interface between the Micron® MT9V022 CMOS digital image sensor and the parallel peripheral interface (PPI) of Blackfin® processors. The document specifically describes the connection using the ADSP-BF561 processor but notes that the PPI interface is fully compatible across all Blackfin derivatives with a PPI.
The guide provides schematics for connecting the Micron head board to the ADSP-BF561 EZ-KIT Lite evaluation system via a Blackfin A-V EZ-Extender board. It explains the configuration of the PPI in general-purpose (GP) input mode, including settings for clock polarity and frame sync signals, along with example code for data transmission.
The system was tested on the ADSP-BF561 processor.
Yes, it applies to other Blackfin processors with PPI because their interface is fully compatible.
