;// OPTION 2 lets you interface the display using ANY TWO or THREE PINS,// tradeoff being that performance is not as fast as hardware SPI above.//#define TFT_MOSI 11 // Data out//#define TFT_SCLK 13 // Clock out
create a unique timepiece, the customization option allows you to make the display truly your own. Additionally, the programmable nature of the LED display board means that you can easily set the time or create dynamic displays, making it a valuable tool for both hobbyists and professionals ...
// OPTION 1 (recommended) is to use the HARDWARE SPI pins, which are unique // to each board and not reassignable. For Arduino Uno: MOSI = pin 11 and // SCLK = pin 13. This is the fastest mode of operation and is required if // using the breakout board's microSD card. // F...
在共阴极RGBLED中,您为特定引脚提供电源(HIGH)以打开颜色。对于共阳极RGBLED,将特定引脚接地(LOW)以打开颜色。 因此,对于普通阳极RGBLED,要设置颜色,您需要在应用之前从最大值(即255)中减去每个颜色值。此反转可确保特定颜色的值为255(全强度)会导致该颜色被关闭,而值为0(无强度)会导致该颜色完全打开。 RGBLED...
