程序员专用键盘
本帖最后由 question 于 2021-6-22 20:27 编辑闲着没事搞个键盘玩玩，上正片哈哈。
打开立创eda，点下这个 点下那个就这样了。
立创直接打板
rgb灯 热插拔轴，玩得有点hi
rgb测试代码// NeoPixel test program showing use of the WHITE channel for RGBW
// pixels only (won't look correct on regular RGB NeoPixel strips).
#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif
// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1:
#define LED_PIN A5
// How many NeoPixels are attached to the Arduino?
#define LED_COUNT3
// NeoPixel brightness, 0 (min) to 255 (max)
#define BRIGHTNESS 50 // Set BRIGHTNESS to about 1/5 (max = 255)
// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRBW + NEO_KHZ800);
// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 3 = Pixel type flags, add together as needed:
// NEO_KHZ800800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)

//define the symbols on the buttons of the keypads

{'1','2'},
{'3','4'}

void setup() {
Serial.begin(9600);
customKeypad.begin();
}
void loop() {
// put your main code here, to run repeatedly:
customKeypad.tick();
while(customKeypad.available()){
keypadEvent e = customKeypad.read();
Serial.print((char)e.bit.KEY);
if(e.bit.EVENT == KEY_JUST_PRESSED) Serial.println(" pressed");
else if(e.bit.EVENT == KEY_JUST_RELEASED) Serial.println(" released");
}
delay(10);
}
自己根据需求改键盘代码就好
