Waveshare 1.5inch RGB OLED Module #174

Hey Guys, first of all, great work! I worked on accomplishing the tasks this project does with c and fbcp, but I did not get good results. Then I accidentally found this project. The project name makes it hard to find this project though. I tried this out for the Waveshare 1.5inch RGB OLED Module (128x128), which can be found here: https://www.waveshare.com/wiki/1.5inch_RGB_OLED_Module

It has the SSD1351 driver. By updating the height in ssd1351.cpp and ssd1351.h it worked like charms! I used these options: cmake -DSSD1351=ON -DGPIO_TFT_DATA_CONTROL=24 -DGPIO_TFT_RESET_PIN=25 -DSPI_BUS_CLOCK_DIVISOR=30 ..

Also in config.h you need to uncomment to not have some frameshifting issues. #define UPDATE_FRAMES_WITHOUT_DIFFING

No issues, I just wanted to tell you: Great job!

I believe the root cause for the issue is something else, and using #define UPDATE_FRAMES_WITHOUT_DIFFING masks the issue by not having to send partial write windows. What the something else is, might be a bit trickier to find out. But if performance is good 60fps already with UPDATE_FRAMES_WITHOUT_DIFFING (on a 128x128 display it might), then may not be worth tweaking further.
