What kind of data is it? You can use DCT to store this if you would like to access it often.
Can you provide more details as to what format of data you would like to store?
Thanks for the replay,
I want to display the different images on OLED. Each image holds 32768 bytes (binary or hex or unsigned char image_array). If i am able to write these binaries or hex on SPI flash, then I can read the data from the SPI flash and display the image on OLED.
To use DCT,
DCT1 + DCT2 = 32k, Even my single image holds 32768 bytes.
Thanks & regards,
You can create a file system image or resource image on the sflash and store resources there and refer from your code

I met the same problem with you, I need to write a big Chinese font code(512KB) to the spi flash, then read it and display the font on the OLED screen. I have study this for days, still can't solve it perfectly, would you like to share some of your example code? Thank you.
