[SOLVED] 3. HAL Everloop LED Array And IMU #9

Closed nebiljabari closed 7 years ago

nebiljabari commented 7 years ago

Ive check and re-check many times and I think I followed correctly the steps but I was unable to get the demos/everloop_demo work. No led get lighted

When I run demos/arc_demo I get random light (blue, red, green, white) on random upper LED and almost all the LED on the bottom part are off. When I do ctrl c after demos/arc_demo the LED lighten stay on until I reboot

Im on a RaspberryPi 3 Model B (ssh remote control with Macbook Air and wifi) - All packages are update - The small SAM3 MCU LED flash every 1s - SPI enabled

@nebiljabari random light patterns are usually associated with bad power supply unit. MATRIX Creator needs 2A, 5.0V, low ripple PSU.

@eljuguetero "You was right", now my Matrix look like a real UFO ! Thx to Flynnprgmmr for his post on the forum

I know we should but who read the safety guide ?

WARNINGS This product shall only be connected to an external power supply rated at 5V DC, with a minimum amperage of 2A

I think it really deserve a note in the wiki Getting Started page
