Thanks alphanumeric for your assistance. I have been using the new Pimoroni UF2 with the graphics infomation and the jpeg routine but unfortunately it is too slow to repeatedly load and redraw the screen for what I need. It does not seem to have an option to directly load in an rgb332 or rgb565 file directly into the screen buffer memory (which would be faster).
In alternative UF2s I have seen that they have a Framebuffer option, into which you can load in a file then display it, seen at
https://docs.micropython.org/en/latest/library/framebuf.html
You first create a block of the correct size, load in a rgb565 file then update the display, which I hope would be quicker that doing repeated jpeg conversions. An example can be seen here:
I have listed the main points:
import framebuf
TH = bytearray()
fb = framebuf.FrameBuffer(TH,64,64, framebuf.MONO_HLSB) # THIS defines the file to load
oled.fill(0)
oled.blit(fb,32,0) # THIS IS GETTING FILE DATA onto display at x, y
oled.show()
What I am looking for is something similar to the above, hence my post to ask if the new Pimoroni UF2 has this option anywhere or can it be simulated, knowing that speed is of the essence. It is probably there and I have missed it.
I have resurrected my old PC program I created to convert BMP files to rgb332/565 files and want to load them into the pico and display as quickly as possible.
Thanks
