Hey guys,
I'm developing an HDMI driver for the i.IMX6 board. This is my first time writing a driver so I'm a little new to this. I was looking for two specific features present in the HDMI configuration registers that I can't seem to find:
1. Can you set a specific pixel to be a certain RGB value?
- In the SDK code for the HDMI there's a nice way to force the entire screen to be one color but not an individual pixel.
2. Is there a way to disable/enable the backlight, turn on/off the screen via the HDMI config registers? Based on previous i.MX boards this was done by altering one simple register. Is it the same for i.MX6?
Thanks!
1. Can you set a specific pixel to be a certain RGB value?
> what specific pixel do you need to set? pls give me detailed case for check
2. Is there a way to disable/enable the backlight, turn on/off the screen via the HDMI config registers?
> via HDMI config register? no, hdmi config register couldn't control backlight. you can refer to the "imx6q_add_mxc_pwm_backlight" fucntion in the "arch\am\mach-mx6\board-m6q_sabresd.c". imx products have the familiar PWM module.
what specific pixel do you need to set? pls give me detailed case for check
> For instance, I want to set pixel 250,59 to the RGB value 35,20,16 (totally random).
