1.4 MIPI CSI-2 Block Configuration APIs
The MIPI CSI-2 Rx-block configuration APIs allow user applications to initialize, configure, and perform power
management for the camera interface. These APIs communicate with the camera over the I
2
C bus.
For modularity, the MIPI CSI-2 configuration APIs are compiled into a separate API library (cyu3mipicsi.a).
This library is linked with the application only if its functionality is required.
The main APIs provided in the API library are as follows:
Table 2: CX3-Specific APIs in the EZ-USB FX3 SDK
API Name
API Description
CyU3PMipicsiInit()
API to initialize the MIPI CSI-2 block.
CyU3PMipicsiDeInit()
API to de-initialize the MIPI CSI-2 block.
CyU3PMipicsiSetIntfParams()
API to configure the clocks and interface settings on the MIPI CSI-2
block.
CyU3PMipicsiQueryIntfParams()
API to query settings from the MIPI CSI-2 block.
CyU3PMipicsiSleep()
API to place the MIPI CSI-2 block in the low-power sleep mode.
CyU3PMipicsiWakeup()
API to wake the MIPI CSI-2 block from the low-power sleep mode to
active mode.
CyU3PCx3DeviceReset()
API to reset the MIPI CSI-2 block.
CyU3PCx3DeviceReset()
API to perform a warm or cold reset on the CX3 device.
CyU3PMipicsiSetSensorControl()
API to drive the MIPI CSI-2 XRESET and XSHUTDOWN signals to the
image sensor.
XRESET is a CX3 output signal that can be used to reset the image
sensor.
XSHUTDOWN is a CX3 output signal that can be used to control
image sensor power modes.
CyU3PMipicsiGpifLoad()
API to load the fixed-function GPIF II waveform and configure the
fixed-function GPIF II bus widths and DMA buffer size.
More information on the APIs is available in Section 1.11
Detailed API documentation is available in the MIPI CSI-2 and Fixed-Function GPIF Interface for CX3 section
of the EZ-USB FX3 SDK Firmware API Guide, available as part of the EZ USB FX3 SDK.
