How we could work with multiple MAX7219 LED 8×8 matrices connected in a chain, light up some LEDs, and use a memory buffer to save the current state of the LEDs. In our previous tutorial, we discussed how to create an interface between the ATtiny85 microcontroller and MAX7219 controller and connect a single 8×8 LED matrix. The … Learn more …
In our previous tutorial, we discussed how to create an interface between the ATtiny85 microcontroller and MAX7219 controller for LED matrices. We created 4 basic functions: max7219_byte, max7219_word, max7219_init, and max7219_row and they work great with a single 8×8 LED matrix. Let’s take a step further and connect more LED 8×8 matrices. What’s our goal? … Learn more …
What’s our goal? To connect a MAX7219 based LED Matrix module to an ATtiny85 microcontroller and control the LEDs. Doesn’t sound very complicated, right? The Titorial We wrote a short tutorial about how MAX7219 modules work, how to connect them to ATtiny85, and how to write a simple library to work with them Continue reading the MAX7219 ATtiny85 tutorial … Learn more …
What’s our goal? To connect a MAX7219 based LED Matrix module to an ATtiny85 microcontroller and control the LEDs. Doesn’t sound very complicated, right? The Hardware The MAX7219 controller manufactured by Maxim Integrated is a compact, serial input/output common-cathode display driver that could interface microcontrollers to 64 individual LEDs, 7-segment numeric LED displays of up … Learn more …
MAX7219tiny is a C library for working with the MAX7219 display driver to control an 8×8 LED matrix. It is intended to be used with the Tinusaur boards but should also work with any other board based on ATtiny85 or a similar microcontroller.
