STM32MP1 Series interfacing with a MIP® CSI-2 camera IApplication note
■This application provides information on how to interface STM32MP1 Series with a MIPI CSI-2 camera. The STM32MP1 Series, like the STM32 high-performance MCUs can address CMOS camera sensors through its DCMI (digital camera module interface) parallel port. However, it is possible to extend the range of addressable camera sensors for instance MIPI® CSI-2 cameras (camera serial interface), thanks to the STMIPID02 MIPI CSI-2 deserializer discrete component.
■The MIPI CSI-2 interface protocol has become for many years the standard technology in today’s embedded sensors, mostly driven by the mobile market and it is also widely used in the industrial market where MIPI CSI-2 brings decisive advantages, offering a lower pin count and cost versus the conventional parallel interface or MIPI CPI.
■The STMIPID02 MIPI CSI-2 deserializer can address a broad range of MIPI CSI-2 camera sensors used in mobile devices and automotive applications. This direct interface removes the requirement for associated software overhead linked to frame decoding (for camera over USB or Ethernet for instance).
The purpose of this application note is to demonstrate, using the DH96 Avenger board, the STM32MP1 Series capability to address the 5 Mpixel OV5640 MIPI CSI-2 camera sensor through the STMIPID02 MIPI CSI-2 deserializer. Both drivers are available and included in the STMicroelectronics OpenSTLinux software distribution package. For the purpose of this application note and according to the STMIPID02 deserializer specifications, the focus is made exclusively on the MIPI CSI-2.1 protocol over a D-PHY.
