在我的情况下,当为 Arduino 供电时,LED 矩阵闪烁并且文本没有完全显示。这是因为 MAX7219芯片对任何电压干扰都非常敏感。 为了解决这个问题,我在 LED Matrix VCC(+) 和 GND(-) 之间添加了一个 47uf电解电容,确保正确连接电容,+ on (VCC) 和 - on (GND) ...
选择“ Counter1 ”并在属性窗口中将Max>Value设置为 0 并将Min>Value设置为 -170注意:-170 是 X 上的距离(文本的长度),文本将从左向右移动,你可以玩这个数字以获得正确的长度选择“ TextValue1 ”并设置“ Value”(这是您要在 LED 矩阵上显示的文本):ARDUINO LED MATRIX PROJECT 选择“ LedController1 ”...
