How to pass data to my model?

HI!

I am newbie to CUBE AI.

I m working on implementing my CNN network that takes input image of 128,128,1 (greyscale) and give an output of 3 classes {class1,class2,class3}.

i did convert and try my model to TFLITE successfully on python.

then i went to stmcube and did put the model using X-CUBE-AI application template .

my problem is with

int acquire_and_process_data(ai_i8* data[])
{
  /* fill the inputs of the c-model
  for (int idx=0; idx < AI_NETWORK_IN_NUM; idx++ )
  {
      data[idx] = ....
  }

  */
  return 0;
}

my input buffer is like this

#define AI_NETWORK_IN_1_FORMAT      (AI_BUFFER_FORMAT_FLOAT)
#define AI_NETWORK_IN_1_HEIGHT      (128)
#define AI_NETWORK_IN_1_WIDTH       (128)
#define AI_NETWORK_IN_1_CHANNEL     (1)
#define AI_NETWORK_IN_1_SIZE        (16384)
#define AI_NETWORK_IN_1_SIZE_BYTES  (65536)

i tried putting image as image [128*128] and image[128][128]
