# LCD Shield Example
#
# 注意：要运行此示例，您需要为OpenMV Cam配备LCD Shield。
#
# The LCD shield allows you to view your OpenMV Cam's frame buffer on the go.

# Initialize the lcd screen.
# 注意：如果支持，可以使用DAC或PWM背光控制器来控制
# 背光强度：
#  lcd = display.SPIDisplay(backlight=display.DACBacklight(channel=2))
#  lcd.backlight(25) # 25% intensity
# 否则使用默认的GPIO（开/关）控制器。
#  OpenMV Cam M4/M7/H7/H7 Plus -> DAC and GPIO Support
#  OpenMV Cam RT1062 -> GPIO Support
#  OpenMV Cam N6 -> PWM and GPIO Support
