Modify screen width

[Ultramxn]

Hello,
I have a ST7657 12232 LCD cannot display anything with 12232 constructor in u8g2 but display well with OS12864 constructor except skipping six pixels on the left of the screen, that is, missing first character in the test. May I ask can we override screen width of a constructor by passing parameter?

What are the exact names of the constructors?

Graphics test results are uploaded for your convenience.

Many thanks.

Thanks for your prompt reply ! The constructors are: U8G2_ST7567_122X32_F_4W_SW_SPI // which displayed nothing. and U8G2_ST7567_OS12864_F_4W_SW_SPI // display test screen but missing left most six pixels. Regards. 自我的 Galaxy 發送

I don't know whether it is worth to change or add new constructor for a custom lcd, however, it may leading problem to reappear after every update of the library. Anyway, many thanks to your help and I can print to the lcd without missing pixels now.
By the way, can we pass offset as a optional parameter along with the pin numbers to the constructor module? It may reduce lots of modification hereafter.

This would be a much bigger effort than just creating a new constructor... So if you are willing to test and give some feedback to a new constructor, then I will create the same.
