Saving snapshot to sd cardd

[anku2424]

Hi team,

I wanted to save snapshot taken by maix one dock board to the sd card. Here's the code I wrote for it.

`#include <Sipeed_OV2640.h>
#include <Sipeed_ST7789.h>

#include<SD.h>

SPIClass spi0(SPI0); // MUST be SPI0 for Maix series on board LCD
Sipeed_ST7789 lcd(320, 240, spi0);

Sipeed_OV2640 camera(FRAMESIZE_QVGA, PIXFORMAT_RGB565);

File myFile;
File myFile2;
File myFile3;
File myFile4;

#define SWAP_SMALL(x) (x >> 8 & 0xff)
#define SWAP_16(x) ((x >> 8 & 0xff) | (x << 8))
#define LCD_MAX_PIXELS (76800)

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
delay(100);
Serial.print("Initializing SD card...");

if (!SD.begin(29)) {
Serial.println("initialization failed!");
while (1);
}
Serial.println("initialization done.");

myFile = SD.open("forl2.txt", FILE_WRITE);

lcd.begin(15000000, COLOR_RED);
lcd.invertDisplay(true); // comment this out when camera is on the backside

Serial.print("camera init ");
if(!camera.begin())
Serial.println("failed");
else
Serial.println("success");
camera.run(true);

delay(100);

uint8_t* img = camera.snapshot();

if (myFile) {
for (uint32_t i=0;i<320240;i+=2) {
myFile.write((img+i+1));
myFile.write(*(img+i));
}

Serial.println("file written successfully");

}
else {
Serial.println("FIle opening failed");
}

myFile.close();
}

void loop() {
// put your main code here, to run repeatedly:
}`

Then I wrote a python code using PIL library to display the image saved by maix 1 dock board.

`import numpy as np
from PIL import Image
from numpy import asarray

data = list()

with open("FORL2.txt", "rb") as f:
byte = f.read(1)
while byte != b"":
# print (byte)
data.append(int.from_bytes(byte, "big"))
# Do stuff with byte.
byte = f.read(1)

data = np.array(data)
image_array = np.reshape(data, (240, 320))

image2 = Image.fromarray(image_array)

image2.show()`

I took the image of my face but here's the image that was displayed by the python code -

Where am I going wrong?
