STM32+0V7670图像传送上位机显示

ALEX_LAM · 发表于 2015-11-19 13:13:50

采用的是RGB565格式，通过STM32采集像素点，每个像素点是16位，设置了一个外部SRAM的60K左右的数据，将每个像素点以16位的格式存储进该数组，然后当每存储完一帧图像就通过串口1传向上位机，但发现，上位机显示的图片是黑白的，可我发送的是RGB565格式像素点，请问是否不能设置RGB565发送，还是我的程序上的问题，如下为部分程序：

#define Color_Space 70*1024
u16 Picture_Color[Color_Space] __attribute__((at(0X68000000)));

void Send_0ne_Buf(USART_TypeDef* USARTx,u8 c)//·???????×?·??¨8???©
{
assert_param(IS_USART_ALL_PERIPH(USARTx));
USART_SendData(USARTx, c);
while(USART_GetFlagStatus(USARTx, USART_FLAG_TC)!=SET);//??????·?·????ê????
}

void Send_Picture(USART_TypeDef* USARTx,uint16_t *c)//·??????????????ú
{
u32 i;
u16 *p;
p=c;
assert_param(IS_USART_ALL_PERIPH(USARTx));
Send_0ne_Buf(USARTx,0x01);//?????ú??é
while(*p!='\0')
{
  USART_SendData(USARTx, *p);//?®??·???????
  while(USART_GetFlagStatus(USARTx, USART_FLAG_TC)!=SET);//??????·?·????ê????
  p++;
}
Send_0ne_Buf(USARTx,0x01);
}
