ESP32 LCD2004 - write works, set_cursor doesn't

[gregkerr]

This is connected to an LCD2004 display on ESP32. Library looks great, and write() works just fine, but using set_cursor does not (or I'm using it wrong (e.g. - set_cursor( 1, 1)). Using set_cursor() just produces 6-7 garbage characters in the upper left hand corner of the screen. Simple repro code:

i2c = I2C(-1, sda=Pin(21), scl=Pin(22))
lcd = LCD_I2C(i2c, i2c.scan()[0], 20, 4)
lcd.set_cursor(1, 1)
lcd.write("STS-126")

Hi @gregkerr, thanks for the feedback. Unfortunately I still don't have a 20x04 module to test corrections, but I'm thinking about how I can fix the error without it. I apologize for the late return.
