ToughC5 触摸屏相关 API 与案例程序。
3.3.9M5ToughC50.2.220.2.28#include <M5Unified.h>
#include <M5GFX.h>
m5::touch_detail_t touchDetail;
int width, height;
void setup() {
M5.begin();
M5.Display.setRotation(1);
M5.Display.setFont(&fonts::DejaVu24);
width = M5.Display.width();
height = M5.Display.height();
Serial.begin(115200);
Serial.println("Start touching!");
M5.Display.print("Start touching!");
}
void loop() {
M5.update();
touchDetail = M5.Touch.getDetail();
if (touchDetail.isPressed()) {
Serial.printf("x:%d, y:%d\r\n", touchDetail.x, touchDetail.y);
for (int i = 0; i < width; i += 10) {
for (int j = 0; j < height; j += 10) {
uint8_t cr = map((touchDetail.x - i) % width, 0, width, 0, 256);
uint8_t cg = map((touchDetail.y - j) % height, 0, height, 0, 256);
uint16_t color = M5.Display.color565(cr, cg, 255 - (cr + cg) / 2);
M5.Display.fillRect(i, j, 10, 10, color);
}
}
}
}当手指触摸屏幕时,程序会通过串口输出触摸点坐标,并让屏幕上的彩色阵列跟随触摸点移动。
ToughC5 触摸屏部分使用了 M5Unified 库中的 Touch_Class,更多相关 API 可以参考下方文档:
