pxp_blend#
Overview#
The PXP blend project shows how to blend process surface and alpha surface using PXP. If this example runs correctly, you will see two rectangles moving in the screen. One rectangle is process surface output, and the other is alpha surface output, the overlay region color is OR’ed value of process surface and alpha surface.
Supported Boards#
EVK9-MIMX8ULP
Hardware requirements
Micro USB cable
MIMX8ULP-EVK/EVK9 board
J-Link Debug Probe
5V power supply
RK055AHD091(rm68200) panel or RK055MHD091(hx8394) panel or monitor(support HDMI input)
Board settings
Connect the MIPI panel to MIMX8ULP-EVK board J18. Connect J1 of board to monitor. (optional: if choose monitor to test the demo, need do this)
Prepare the Demo
Connect 5V power supply and J-Link Debug Probe to the board, switch SW10 to power on the board.
Connect a micro USB cable between the host PC and the J17 USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Build example to generate sdk20-app.bin
Generate flash.bin with imx-mkimage and download it according to Getting Started doc
Open two serials lines provided at J17 USB port. (e.g. /dev/ttyUSB0~3, /dev/ttyUSB2 for A Core, /dev/ttyUSB3 for M Core)
Press the reset button on your board and boot to uboot and let uboot not using diplay peripherals => setenv video_off yes;saveenv then re-power on the board
Let Stop in Uboot.
Steps to configure the panels
RK055MHD091 panel is used by default and the default setting for APP_DISPLAY_EXTERNAL_CONVERTOR is disabled.
When Kconfig is used
Below setting is for kconfig, you can fix below settings in prj.conf under example folder For default panel, you do not need to change anything. For RK055AHD091(rm68200) panel: CONFIG_DEMO_PANEL_RK055AHD091=y
For HDMI monitor: CONFIG_APP_DISPLAY_EXTERNAL_CONVERTOR=y
When package is used
Below setting is for mcux_config.h. For RK055AHD091(rm68200) panel: Setting DEMO_PANEL to 0 to choose RK055AHD091 panel. For HDMI monitor: Setting APP_DISPLAY_EXTERNAL_CONVERTOR to 1.
