Hi guys,
I got a new score on refreshing rate.
this doge.bmp is a 24bit bmp with a width of 80 pixel and gets a horrible 3900 FPS, that squeezes the image
okay, when it goes to DMASPI it turns out that FPS depends highly on micro-SD cards, but not by size (as this one uses a 128Mbyte card, could be pretty old)
I'm still finding if there is something deciding.
other finding:
when using apa102 chain over 80pixels, dont go over 12Mhz or the pixels chained faraway (>~80) goes crazy,
my crazy leds happen on 16Mhz, by 144 LEDS only the far LEDS goes wild, but same script and hardware fine at 12Mhz.
