java byte数组转String String(byte[] bytes) 构造器 这是最简单的转换方法,它使用平台默认的字符集来解码byte数组。...(str); // 输出: Hello String(byte[] bytes, int offset, int length) 构造器 这个方法允许你指定byte数组的子序列进行转换,通过offset...byte[] bytes = new byte[]{72, 101, 108...

Finally, we perform the conversion from int to float by assigning the int variable to the float variable. For this we use the float() function: myFloat = float(myInt); The “float()” function converts the integer value to a floating-point number. ...
void drawBitmap(int16_t x, int16_t y, uint8_t *bitmap, int16_t w, int16_t h, uint16_t color); 这将向显示器发送一个连续的位块数据,其中每个“1”位将相应的像素设置为“color”指定的颜色,而跳过每个“0”位。x, y是绘制位图的左上角,w, h是以像素为单位的宽度和高度。
