Rattling sound when SD card image is changed on the display
Hi all. CrowPanel Advance 5
I'm trying to make a project which functionality includes outputting images in jpg format from SD-card. I managed to implement it in the test version. But during the image change a sound like rattling can be heard. Which disappears after the image has been displayed and so on until the next image is displayed. At the same time I tried the lesson with a test output images in bmp format and there are no extraneous sounds.
From what I tried on my own:
Line-by-line output
Reduce SPI frequency for SD card
Loop delay between SD card and display operations
Decrease cfg.freq_write to
Disable DMA
Any help is welcome.
