Po Ting

update : I tried a "W25Q512" WSON8 package on back to T4.1, which gives 64MB, and a whooping 4434 FPS (over 4000 probably was buggy for some SPI LEDs if PWM not enough fast...) when using 160 pixel bmps, so quite enough for me. guess a W25N01...

Hi, I currently don't solder the 2020 LEDs myself anymore, I order from internet PCBA... mostly I encounter data/clk pin shorts to Vcc or gnd, which is obvious as I can see the LEDs aren't updating after a specific LED, just check the pins nearby...

oh,, just found that WSON package is probably hand solder-able?

Yes I mean flash, but flash for otherwise file MTP usage not used for program. I mean physically, I am using Teensy 4.1 and it's back side pad on backside with a winbond 128Mbit chip, trying to replace/compete with my SDIO version( using the SD...

Hello community and good morning : Still working on my persistence of vision project with a new 160HD and T4.1 version (https://forum.pjrc.com/index.php?threads/posted-venti-pov-v2-0-80hd.53088/#post-361041) it's almost done with SDcard/sdio...

Yeah, this chip really wants a well tuned reflow soldering oven! I'm trying again... this time with 8 resistors. Looks weird, but I can visually inspect every pin.

You can use the 16mb version found on Micromod Teensy

actually should be this, getting my latest PCB design and it should be all done
