Animation wont work

[Tadeas-grohmi]

Hi, Im pretty new to python I2C lcd. So I was trying some kind of animations and changing text on screen.
When I try this code
for i in range(0, 19): lcd.cursor_pos = (2, i) lcd.write_string("\x01") time.sleep(1)
It just write the char to i = 12, then it write a char in position x00 and then it stops. Any one know what the issue could be? Im using the 20x4 and PCF8574. Thanks for help.
