RT1062 LCD Shield No Attribute SPIDisplay

OpenMV Boards

When I try to run the LCD Shield Example on the RT1062 with firmware V4.5.9, I get the error AttributeError: ‘module’ object has no attribute ‘SPIDisplay’

The default example works with v4.5.9 for me:

import sensor
import display

sensor.reset()  # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565)  # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QQVGA2)  # Special 128x160 framesize for LCD Shield.
# Initialize the lcd screen.
# Note: A DAC or a PWM backlight controller can be used to control the
# backlight intensity if supported:
#  lcd = display.SPIDisplay(backlight=display.DACBacklight(channel=2))
#  lcd.backlight(25) # 25% intensity
# Otherwise the default GPIO (on/off) controller is used.
lcd = display.SPIDisplay()

while True:
    lcd.write(sensor.snapshot())  # Take a picture and display the image.

Not sure what’s going on. I have an RT1062 with 4.5.9 too and the script works…

Can you click the Firmware Version label in the IDE and reset it to the release?

5

Clicked on Firmware Version label and reset to release version. Firmware was reloaded. Firmware VErsion4.5.9 - [latest]. Still getting no attribute ‘SPIDisplay’

firmware.zip (1.7 MB)

I just flashed this version and it works on my RT1062? v4.5.9

7

Flashed that firmware to my RT1062 and still same error with example lcd_1.py. Very strange.

8

Not sure what to do here… I’ve flashed it to my camera a few times and it works as expected.

Tools → Installing the latest dev release works fine too.

Erased SD card, rebooted computer, reinstalled latest release firmware, tapped my head and rubbed my stomach … and now it works :slight_smile:

Issue returned. I have two RT1062. lcd = display.SPIDisplay() works on one, but on the other I get AttributeError: ‘module’ object has no attribute ‘SPIDisplay’. Does SPIDisplay look for something on the SD card? When I erased all of my .py files from the SD card the error went away. Then when I put them back on the SD card the error returned.

Can you import the display module and then do print(dir(display))? It sounds like the display module is getting messed up by a file on your uSD card.

You should see SPIDisplay in the list.

That was it. I had another module named Display.py (capital D) on the SD card that was colliding. Thanks for your assistance.
