MAX7219 Dot Matrix Module 4-in-1 LED Display Module
レビューの一部は自動翻訳されています。
I first tried the dotMatrix on the Arduino with the Sprite and Matrix libraries. I got funny results because the column adressing is reversed. Therefore I switched to the MD_MAX72xx libraries. Make sure to change the define in the MD_MAX72xx. h file to read: #define USE_FC16_HW 1 I used the MD_Keyswitch library found at https://github.com/MajicDesigns/MD_KeySwitch and the MD_MAX72xx library found at https://github.com/MajicDesigns/MD_MAX72XX Then I pulled the source at https://github.com/MajicDesigns/MD_MAX72XX/blob/master/examples/MD_MAX72xx_ScrollChart/MD_MAX72xx_ScrollChart.ino With that you should be able to get it to work. If you use pins that are not-SPI standard, make sure to activate the call to MD_MAX72XX with four parameters, and comment out the one with two parameters.
非常に良い製品と良い価格。 その仕組みがわからない場合は、良いチュートリアルを1つ見つけました。 https://www.makerguides.com/max7219-led-dot-matrix-display-arduino-tutorial/ プログラムを試して、彼らは最初の1つで動作していないことがわかります。 使用するピンの名前を変更し、Arduinoでプログラムを再読み込みしてください。 例: CS_PIN 10 データPIN 11 CLK_PIN 13
made it work with an Esp8266 board easily. good for the project I'm doing.
Excellent product. Thank you Banggood. Tip: If you use the MD_parola & MD_MAX72xx libraries, use #define HARDWARE_TYPE MD_MAX72XX::FC16_HW
hello everyone Watch the photos :)
A lot of fun to play around with. I used two of them for scrolling messages through the window. (see pictures) Tip: If you use the MD_parola & MD_MAX72xx libraries, use #define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW for these.
watch the video from great projects max7219/1088as led matrix and all should be fine :) I first plugged in 3v by mistake. the display was erratic. perfect on 5v
matrice led , funziona Ok , difficile da fare funzionare , io sono riuscito con la libreria (md_max72xx.h) con : vedere foto.

all the Led matrix located at the end lifted by the 4 pins connector, making all 4 display not horizontally flat.Package protected by foam, so no breaking.
