RA8875 + 7'' TFT + ARDUINO UNO = WORKING having issues with images loading slow

Former Member
Former Member over 10 years ago

hello I managed to run audio and imaging into my Arduino Uno project.

the project consist off:

 

- RA8875

- Arduino Uno

- MP3 with SD Card

- 7'' TFT Screen

 

Pixels are 800 X 480

the only issue that i am encountering is that the images are taking 1 minute and 30 seconds to fully load up.

images are in bmp format. i was wondering if there is any solution to this problem. 

any feedbacks will be grateful. if images can be done in any other format that can potentially be faster i would gladly take it into consideration as well considering its an arduino.

    Are the images slow when running the MP3? Or without? also what is the clock speed for the SPI interface? It may be the Arduino is 8 Mhz trying to drive the SPI fast and MP3... A video could help here...

    no the image was not slow when running the mp3. I did not set any clock speed, its in its standard clock speed. thank you.

    Can you drop the sketch here? It may need some optimization.
