-Info: RPi-Display - 2.8" Touch Display by Watterott
- Linux has 2 drivers that support this display and this overlay supports
- both.
-
- Examples:
- fbtft/fb_ili9341: dtoverlay=rpi-display
- drm/mi0283qt: dtoverlay=rpi-display,drm,backlight-pwm,rotate=180
-
- Some notable differences with the DRM driver compared to fbtft:
- - The display is turned on when it's first used and not on driver load
- as with fbtft. So if nothing uses the display it stays off.
- - Can run with a higher SPI clock increasing framerate. This is possible
- since the driver avoids messing up the controller configuration due to
- transmission errors by running config commands at 10MHz and only pixel
- data at full speed (occasional pixel glitch might occur).
- - PWM backlight is supported.
-
-Load: dtoverlay=rpi-display,<param>=<val>
-Params: speed Display SPI bus speed
- rotate Display rotation {0,90,180,270}
- fps Delay between frame updates (fbtft only)
- debug Debug output level {0-7} (fbtft only)
- xohms Touchpanel sensitivity (X-plate resistance)
- swapxy Swap x and y axis
- backlight Change backlight GPIO pin {e.g. 12, 18}
- (fbtft only)
- drm Use DRM/KMS driver mi0283qt instead of fbtft.
- Set the SPI clock to 70MHz.
- This has to be the first parameter.
- backlight-pwm Use pwm for backlight (drm only). NB: Disables
- audio headphone output as that also uses PWM.
