Since the latest release of 'piolib' we can do things like drive NeoPixels on any pin on the Raspberry Pi 5 (https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/using-neopixels-on-the-pi-5) which rocks, and means we can tackle the next, more complex, project: driving HUB75 RGB Matrix displays (https://www.adafruit.com/product/5362) these require even MORE timing freakiness: using 10 pins, and 'manual' PWM means we have to constantly blit out the color dithering. Historically this was done with mmap'd memory to the GPIO controller bitbanging, which required a full core and could jitter depending on load. But now we can use the PIO peripheral! We can drive massive display arrays at high speeds and color depths using just about any pins.

The Great Search - How to Source Tariffed & Non-Tariffed Items on DigiKey 12:18

cách đây 1 day trước12:18

12:18

Since this is the topic of the day, we'll be looking at how to purchase an item from DigiKey with tariffs in mind. DigiKey is a free trade zone, which means that if you're not in the USA, you will not have to pay additional tariffs on goods that are re-exported. However, for USA destinations, the new tariffs can add a significant cost if the component has its last manufacturing step in China.…
