mLink 20x4 LCD display with Raspberry Pi - Cursor position not working

[edsyoung]

Hi, I'm using the python mLink library with my Pi 4 model B to control the mlink 20x4 LCD display (bought from HC!)

I've slowed the I2C bus as recommended.

Printing text is working fine but the cursor position command has no effect (no error; no change of cursor position). I tried a delay afterwards, but no change.

Any ideas what is wrong?

Sample code here:

import time
from mLink import mLink

ml = mLink.mLink(1)

ml.cLCD_dispType(0x56, 1)
ml.cLCD_Clear(0x56)

ml.cLCD_Print(0x56, "Hello World xx")

ml.cLCD_Cursor = (0x56, 3, 3)
time.sleep(1)

current_time = time.strftime('%H:%M:%S')
ml.cLCD_Print(0x56, f'Time: {current_time}')

Yes, the issue is caused by the equals sign (=) in your code. You should change this line:

Code: [Select all] [Expand/Collapse]

1.  ml.cLCD_Cursor = (0x56, 3, 3)

...to:

Code: [Select all] [Expand/Collapse]

1.  ml.cLCD_Cursor(0x56, 3, 3)

Thank you!

Corrected and working - I'm feeling very stupid right now...

It's ok, I didn't spot it straight away. TBH, I'm surprised it didn't throw a syntax error.
