Pin Plugs:Apin plug, otherwise known as a jumper wire is a simple wire with a single plug on the end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will...
The cathode is the pin closest to the flat side of the LED. On some LEDs, this pin is shorter than the other pin (see Figure 4-4). 图4-4 LED polarity 将LED 阳极连接到另一个空的 5 引脚轨道。 将一根跳线从阳极的供电轨连接到与 T 形补钉上的引脚 16 相连的供电轨。 从LED 连接的接...
1.首先打开如下路径的配置文件 .pio\libdeps\esp32dev\TFT_eSPI\User_Setup.h 2.更改驱动配置 选择自己屏幕的驱动,并将其他驱动注释 选择显示的RGB顺序,并注释其他RGB顺序(如果不确定可以先选一个,之后看色彩不对再来更改) 选择屏幕显示屏的长和宽,并注释其他长宽 选择屏幕是否反转颜色(如果不确定可以先选一个...

GPIO devices allow for one or multiple pins to be read and written directly. All of these functions are in gpio.h gpio type A handle to one or more pins which can be set simultaneously. gpio gpio_open(int pin) Returns a new handle to a GPIO device for a specific pin on the I/O ...
The backlight will be turned ON when tft.begin() is called, but the library // needs to know if the LEDs are ON with the pin HIGH or LOW. If the LEDs are to be // driven with a PWM signal or turned OFF/ON then this must be handled by the user // sketch. e.g. with ...
