SH1122 Driver for SAM70 MCU

I need a clean, well-structured driver that lets a Microchip SAM70 microcontroller control an SH1122-based OLED. The core requirements are straightforward: Show text (b/w/grey), different fonts (like helvetica, 7segment) and draw simple graphical elements (lines, rectangles, bitmaps, icons SVG).

No use of the library u8g2. We want to switch as we face some problems with other components in our environment.

Expect to work in C/C++, using the SAM70.

Deliverables
• Driver source code with clear headers and inline comments
• One demo task that writes text, and draws a simple SVG graphic so I can verify everything on hardware
• Brief integration notes explaining any required clock, GPIO or SPI settings

Experience and deep knowledge of this driver chip is needed.
