#ifdef SSD1351
// On Adafruit's Adafruit 1.27" and 1.5" Color OLED Breakout Board 128x96 SSD1351 display, the following speed configurations have been tested (on a Pi 3B):
// core_freq=360: CDIV=20, results in 18.00MHz, works
// core_freq=370: CDIV=20, would result in 18.50MHz, this made the screen work for a while, but then hang
// core_freq=375: CDIV=20, would result in 18.75MHz, this made the screen work for a few seconds, but then go blank shortly after
// core_freq=355: CDIV=18, would result in 19.72MHz, this made the screen work for a few seconds, but then go blank shortly after
// Bandwidth needed to update at 60fps: 128*96*16*60 = 11,796,480 bits/sec.
// , so the above obtained best refresh rate allows driving the screen at 60fps.
// Data specific to the SSD1351 controller
#define DISPLAY_SET_CURSOR_X 0x15

#define DISPLAY_WRITE_PIXELS 0x5C

#define MUST_SEND_FULL_CURSOR_WINDOW
// The DISPLAY_WRITE_PIXELS command on this display seems to continue from the x&y where previous command left off. This is unlike
// other displays, where issuing a DISPLAY_WRITE_PIXELS command resets the x&y cursor coordinates.
