I created this simple app to play with animations
import M5
import random
class Snowflake:
def __init__(self):
self.MAX_WIDTH = 320
self.MAX_HEIGHT = 240
self.radius = random.randint(2, 4)
self.velocity = random.randint(2, 5)
self.x = random.randint(0, self.MAX_WIDTH)
self.y = random.randint(0, self.MAX_HEIGHT)
def fall(self):
self.y += self.velocity
if self.y > self.MAX_HEIGHT:
self._reset()
def _reset(self):
self.radius = random.randint(2, 4)
self.velocity = random.randint(2, 5)
self.x = random.randint(0, self.MAX_WIDTH)
self.y = 2
def setup():
global SNOWFLAKES_COUNT
global snow
global circles
SNOWFLAKES_COUNT = 80
snow=[]
circles=[]
M5.begin()
M5.Widgets.fillScreen(0x66b8f7)
for _ in range(SNOWFLAKES_COUNT):
snow.append(Snowflake())
circles.append(M5.Widgets.Circle(0, 0, 0, 0xffffff, 0xffffff))
def loop():
M5.update()
head = M5.Widgets.Circle(160, 144, 25, 0xffffff, 0xffffff)
body = M5.Widgets.Circle(160, 199, 39, 0xffffff, 0xffffff)
nose = M5.Widgets.Triangle(161, 143, 122, 150, 161, 148, 0xEA6511, 0xEA6511)
left_eye = M5.Widgets.Circle(152, 135, 2, 0x000000, 0x000000)
right_eye = M5.Widgets.Circle(167, 135, 2, 0x000000, 0x000000)
for index, s in enumerate(snow):
s.fall()
c = circles[index]
c.setRadius(r=s.radius)
c.setCursor(x=s.x, y=s.y)
if __name__ == '__main__':
try:
setup()
while True:
loop()
except (Exception, KeyboardInterrupt) as e:
try:
from utility import print_error_msg
print_error_msg(e)
except ImportError:
print("please update to latest firmware")
If i run this code from Thonny pressing the run button it works, but if i run it from the the app list, i get this error:
MPY: soft reboot

Anyone knows the cause of this error and how to resolve it?
