These downsides don't mean that CSS grid systems are 'bad', only that as with any tool you should familiarize yourself with the pros and cons to properly determine if it is the right fit for your specific project.

However, while there is plenty of value on offer, there are also a number of downsides to utilizing a system like this. Using CSS grid systems to create layouts like this can be very quick and easy. Let's take a quick look at how the classic 'header, content, sidebar, footer' website layout might be built using techniques common to CSS grids:

Layouts often also include a fixed-width outer container, row containers within it that wrap columns, and set width gutters between columns. However, this isn't the only way to approach grid-based web layouts, and today we're going to examine an alternative.Ī grid system typically consists of a specific number of columns, (commonly twelve or sixteen), and the ability to set an element, (usually a div with a class applied), to a width of X of those columns.įor example, a content area might be set to nine of twelve columns, while a sidebar next to it is set to three or twelve columns. They can be a fantastic time-saving resource, with talented coders having intelligently crafted systems which cater to a wide array of possible layouts designers might need to create.

Color (gamma) correction, and global brightness control features allow for a high level of visual quality control.Over the past few years CSS grid systems have become a very popular way of rapidly producing layout scaffolding in web design.

Up to 48-bit color refresh is available.

Drives all 14 signals on HUB75 panels using 5V buffered outputs, using only 9 GPIO pins on the Teensy 4.0 or 4.1.

Panels can be daisy-chained to make large, bright, high-resolution displays.

Optionally drive DotStar/APA102-compatible LEDs using the onboard 5 volt buffers and 4-pin JST-SM connector.

The 4-pin JST-SM connector may be used to provide power to the Teensy separate from the USB connector.

Signals on the long edges of the Teensy are brought out to expansion rows for easy prototyping.

96 x 96) with high-quality settings, and even larger displays with reduced quality settings.

Drives displays with up 9k pixels (e.g.

Example code is included for a quick start.

SmartMatrix library for Arduino provides an easy development platform, along with others such as FastLED.

Teensy can easily be inserted into and removed from the shield.

If your Teensy has pins, then no soldering is required. All long edge Teensy signals are brought out to expansion rows for easy prototyping. The Teensy is removable, so you can swap between the 4.0 and 4.1 if you want. The shield is easy to assemble and connect to a panel, and there’s no soldering required beyond adding pins to the Teensy.

Global Brightness Control - When you don't need the full brightness of the LED panel, lower the brightness without having to sacrifice color depth of your graphics.

Color (Gamma) Correction - Your source graphics are probably 24-bit color, but SmartMatrix library applies automatic color correction so they have good contrast, smooth gradients, and don't look washed out.

36-bit Color Refresh - See the full-color range in the image or pattern you're displaying, with no noticeable brightness steps when dimming pixels down to black.Advanced features like these are enabled automatically: Use a simple API to tell the library what to draw on the screen, and the library takes care of refreshing in the background. Using SmartLED Shield with SmartMatrix library and the Teensy 4 is the easiest way to drive high-quality and high pixel count graphics to RGB LED panels with a microcontroller. The Shield and library use special features and peripherals of the Teensy 4 processor to send graphics data to your display with minimal CPU usage, so you can use the processor to do other tasks in parallel such as SPI communication, file decoding, or complex rendering. Example code is provided so you can get started as quickly as possible.

The SmartMatrix library for Arduino makes it easy to draw basic graphics, create scrolling and static text, draw beautiful patterns using FastLED, and play animated GIFs on the panel. The example sketches included with the SmartMatrix Library will get you started quickly displaying graphics, patterns, or even animated GIFs from a microSD card on your panel. The SmartLED Shield gives you an easy way to connect up a Teensy 4 or a Teensy 4.1 to one of our RGB LED Matrix Panels. Enter the SmartMatrix SmartLED Shield for Teensy 4! So you have a fresh and fancy Teensy 4 and an RGB LED Matrix Panel and you want an easy way to add graphics to your matrix without having to toss aside your Teensy or do too much soldering.
