GT20L16S1Y GT30L32S4W 横置竖排 转换为 横置横排

参考：https://blog.csdn.net/lljss1980/article/details/126566150

GT20L16S1Y 为横置竖排
GT30L32S4W 为横置横排
暂时为了适配
写了一个适配16 * 16点阵 32 * 32点阵
横置竖排 转换为 横置横排 的算法

/// @brief            转换32字节 16*16点阵 横置竖排   为 横置横排 点阵排列格式
/// @param font       从字库中读取32字节  
/// @param tran       转换后得到32字节
void fontbuf_transfer_32(unsigned char font[32],unsigned char tran[32])
{
int a,i;for(a=0;a<32;a++){tran[a] = 0;}for (a=0;a<8;a++)
{for (i=0;i<8;i++){if ( font[i] & (1<<a) )tran[2*a] |= (1<<(7-i)) ;}
}
for (a=0;a<8;a++)
{for (i=0;i<8;i++){if ( font[i+8] & (1<<a) )tran[2*a+1] |= (1<<(7-i)) ;}
}
