No, the demo could use the internal oscillator.

Actually, the SetBrightness_SSD1351 sub didn't work because I set up a few things wrong. Here's the final revised glcd_ssd1351.h with the SetBrightness_SSD1351 sub working correctly.

I completed the testing and made my changes to glcd_ssd1351.h. I removed the SendMultipleCommand_SSD1351 and SendMultipleData_SSD1351 subs as there doesn't seem to really be any need for them. I also removed the SetBrightness_SSD1351 sub as it doesn't work, even though it should according to the data sheet. It was redundant anyway. The SetContrast_SSD1351 sub works just fine for the purposes of setting display brightness, as well as the relative brightness of the colors. On the rotation, I set it...
