ST7735 FPS - Githubissues

rollalt commented 5 years ago

Raspberry pi 2B Linux raspberrypi 4.19.42-v7+ #1219 SMP

Is there an option to modify the frame rate?

The only things that you can realistically do are:

Try increasing the SPI bus speed parameter - some devices/systems and displays can tolerate 32MHz
Get a faster RPi (I hear the 4B is launched today)
I cant remember off the top of my head whether we implemented the diff-to-previous framebuffer for the ST7735, but if we did, it will only draw the region that changed since the last frame draw - this can significantly speed things up.

I have an idea bubbling to use native linux framebuffers (see https://github.com/rm-hull/luma.lcd/issues/67#issuecomment-500174784), but haven't gotten around to doing any work on that yet - that should improve performance significantly when implemented

Thank you.

@rm-hull diff-to-previous framebuffer for the ST7735, is implemented framebuffer="diff_to_previous" line 276 in device.py.
