在这个网站看到5*7点阵的字库，发现在Arduino显示是垂直镜像效果。
就写了一段程序把其转化成Android的格式，并转化为二进制，方便查看。
这段程序并不是在Arduino IDE运行，是在电脑上用C语言环境运行。
程序很简单，我就不多解释了。
#include
void printb(int val, int n) {
if (n == 2) {
uint8_t v = (uint8_t)val;
printf("B");
for (int i = 7; i >= 0; i--) {
int b = v >> i;
b = b & 1;
printf("%d", b);
}
printf(", ");
} else if (n == 16) {
uint8_t v = (uint8_t)val;
printf("0x%02x, ", v);
}
}
int r2(int v) {
if (v == 1) return 2;
if (v == 2) return 1;
return v;
}
int r4(int v) {
int high = v / 4;
int low = v % 4;
high = r2(high);
low = r2(low);
return low * 4 + high;
}
int reverse(int v) {
int high = v / 16;
int low = v % 16;
high = r4(high);
low = r4(low);
return low * 16 + high;
}
