向PSRAM中写入、读取数据

向PSRAM中写入16位数据

int main(void)
{
	uint16  *point16;
	uint16  data16 = 0x00;
	point16 = (uint16 *)0x80001020;
	while(1)
	{
		*point16=data16++;
	}
	return(0);
}

向PSRAM中低地址处写入8位数据

int main(void)
{
	uint8  *point8;
	uint8  data8 = 0x00;
	point8 = (uint8 *)0x80001010;
	while(1)
	{
		*point8=data8++;
	}
	return(0);
}

向PSRAM中高地址处写入8位数据

int main(void){
 uint8 *point8;
 uint8 data8=0x00;
 point8 = (uint8 *)0x80001011;
 while(1){
 	*point8 = data8++;
 }
 return(0);
}

从PSRAM中读取8位数据

uint8 RcvData8;
int main(void){
	uint8 =  *point8;
	point8 = (uint8 * )0x80001010;
	while(1){
		RecData8 = *point8++;
		RecData8 = *point8++;
		RecData8 = *point8++;
		RecData8 = *point8--;
		point8--;
		point8--
	}

	return(0);
}
