the ST75161 driver for a 160x160 LCD

[18865517180]

When using the ST75161 driver for a 160x160 LCD, I encountered the following issues:
During initialization, the screen orientation was set to U8G2_R0, but the graphics appeared vertically mirrored. Additionally, when displaying across pages (when the character height exceeds 8 pixels), the characters were rendered incorrectly and split into two parts, as shown in the image below.

The display is now functioning correctly after I made the following modifications:

1、In u8g2_Setup_st75161_jlx160160_f, I set the screen orientation to U8G2_MIRROR_VERTICAL.

2、Modified the function u8x8_d_st75161_jlx160160 by changing the line:
u8x8_cad_SendArg(u8x8, (((u8x8_tile_t *)arg_ptr)->y_pos + u8x8->x_offset))
to:
uint8_t physical_page = 0;
physical_page = 19 - ((u8x8_tile_t *)arg_ptr)->y_pos;
u8x8_cad_SendArg(u8x8, physical_page);
Now the LCD display is working properly.

I don't understand what caused the issue with cross-page display. Is it due to the vertical mirroring? This problem can be fixed by modifying the underlying driver.

Each display is different... the u8g2 low level code is for the JLX160x160. I assume you have a display from some other company. Any datasheet for your display?
