hi,
I am currently using BMP + rgb565 LTDC display for GUI icon creation without Touch GFX ( Everything is on "" C"" only and Manual preparation icon using hex converter ).
Already known one is ! for a small size ,BMP is OK but large size BMP icon will increase the size and processing time .
Above Picture size is 6.30KB in BMP
Above Picture size is 2.03KB in JPEG
Visually i could not see any difference BMP and JPEG in my laptop .
Now i am using internal memory for small icon (Now working with stm32h723zgt6 and plan to upgrade to stm32u5 series )
Please clarify my doubts.
0. Can i use Hardware Inbuilt JPEG decoder for JPEG GUI icon creation with rgb565 format ? .
1. Do you think i can achieve best frame rate by Hardware Inbuilt JPEG decoder ?.
2. Either i will get same picture quality like BMP in Hardware Inbuilt JPEG decoder ?
