For the last few years, [Cristiano Monteiro] has marked March 14th by building a device to calculate Pi. This year, he’s combined an RP2040 development board and a beam-splitting prism to create an ...
Library for using the FC-16 display module (based on MAX72xx) with ESP8266 (NodeMCU) and Arduino IDE. There is a very nice display module with MAX7219 and four 8x8 matrix displays. And then there is a ...
When we are talking about the MAX7219-based dot matrix display module, it consists of 64 LEDs connected in a row-column format so that we could easily control them with the multiplexing technique.
There are two objects which must be created to use the library. The MAX72XX object defines the interface to the MAX7219/MAX7221 driver chip; only one MAX72XX object is required for each chain of ...
