print backslash to LCD

[Aadniz]

Hi.

I'm simply trying to create a spinning line effect with these symbols: | / - \

I saw in the docs that it was a few exceptions

0x5C is a Yen symbol instead of backslash

This is the code I'm using:

# write a command to lcd
def lcd_write(self, cmd, mode=0):
    self.lcd_write_four_bits(mode | (cmd & 0xF0))
    self.lcd_write_four_bits(mode | ((cmd << 4) & 0xF0))

# put string function
def lcd_display_string(self, string, line):
    if line == 1:
        self.lcd_write(0x80)
    if line == 2:
        self.lcd_write(0xC0)
    if line == 3:
        self.lcd_write(0x94)
    if line == 4:
        self.lcd_write(0xD4)

    for char in string:
        self.lcd_write(ord(char), Rs)

string = "\\"
lcd.lcd_display_string(string, 1)

Are there any ways to print a backslash?

I would use a custom character. See custom_char(). Print the custom character to the desired position on the screen, then update the character definition in CGRAM and it will update on the display without having to re-write the character again and again.

There are 8 custom characters, so you can have 8 different independent animations.

eg. box that moves from corner to corner:

box0 = bytearray([0x07,0x07,0x07,0x00,0x00,0x00,0x00,0x00]))
box1 = bytearray([0x00,0x07,0x07,0x07,0x00,0x00,0x00,0x00]))
box2 = bytearray([0x00,0x00,0x07,0x07,0x07,0x00,0x00,0x00]))
box3 = bytearray([0x00,0x00,0x00,0x07,0x07,0x07,0x00,0x00]))
box4 = bytearray([0x00,0x00,0x00,0x00,0x07,0x07,0x07,0x00]))
box5 = bytearray([0x00,0x00,0x00,0x00,0x00,0x07,0x07,0x07]))
box6 = bytearray([0x00,0x00,0x00,0x00,0x00,0x0E,0x0E,0x0E]))
box7 = bytearray([0x00,0x00,0x00,0x00,0x00,0x1C,0x1C,0x1C]))
box8 = bytearray([0x00,0x00,0x00,0x00,0x1C,0x1C,0x1C,0x00]))
box9 = bytearray([0x00,0x00,0x00,0x1C,0x1C,0x1C,0x00,0x00]))
box10 = bytearray([0x00,0x00,0x1C,0x1C,0x1C,0x00,0x00,0x00]))
box11 = bytearray([0x00,0x1C,0x1C,0x1C,0x00,0x00,0x00,0x00]))
box12 = bytearray([0x1C,0x1C,0x1C,0x00,0x00,0x00,0x00,0x00]))
box13 = bytearray([0x0E,0x0E,0x0E,0x00,0x00,0x00,0x00,0x00]))
