isi_dwc_mipi_csi2_yuv422#
Overview#
This example shows how to use ISI to receive camera frame through MIPI CSI2.
In this example, the camera input frame is YUV422 format and ISI output frame is RGB565 format. The output frame is shown in the screen.
NOTE:
the example is for newly Synopsys DWC MIPI CSI2 driver and IMX95 platform.
This example must run continously to get the right result, breaking during debug will results to display tearing. Because the ISI driver maintains IP state through ISR, if the core is halted, then driver state does not match the IP state. When exiting debug, the core might be halted for a short while, so the tearing may happen when exiting debug.
If the camera and LCD panel resolutions are not the same, then only part of the camera frame will be shown.
Supported Boards#
IMX952LPD5EVK-19
Hardware requirements
Micro USB cable
IMX952LPD5EVK-19 board
J-Link Debug Probe
12V~20V power supply
Personal Computer
DUAL LVDS panel
AP1302 sensor
Board settings
For DUAL LVDS panel(1920*1200), connect MINISAS ports J15 and J16 to panel. For AP1302 sensor with MINISAS connect to MIPI-CSI1 interface(J13) set SW9 JTAG_UART5_SEL to ON if use Jlink to load firmware.
Prepare the Demo
Connect 12V power supply and J-Link Debug Probe to the board, switch SW4 to power on the board.
Connect a micro USB cable between the host PC and the J31 USB port on the cpu board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Launch the debugger in your IDE to begin running the example.
Note:
the ap1302 is an external isp, it need special firmware from OnSemi GitHub. pls download ap1302_60fps_ar0144_27M_2Lane_awb_tuning.bin from: https://github.com/ONSemiconductor/ap1302_binaries/tree/main/NXP_i.MX93
download fw in to this location: ${SdkRootDirPath}/components/video/camera/device/ap1302/ap1302_60fps_ar0144_27M_2Lane_awb_tuning.bin, combine it into one bin file.
