Detailed Description

Used for iterating over the data frames via the sensor_decoder_api.

Example usage:

(.c)
   struct sensor_decode_context ctx = SENSOR_DECODE_CONTEXT_INIT(
       decoder, buffer, SENSOR_CHAN_ACCEL_XYZ, 0);
 
   while (true) {
     struct sensor_three_axis_data accel_out_data;
 
     num_decoded_channels = sensor_decode(ctx, &accel_out_data, 1);
 
     if (num_decoded_channels <= 0) {
       printk("Done decoding buffer\n");
       break;
     }
 
     printk("Decoded (%" PRId32 ", %" PRId32 ", %" PRId32 ")\n", accel_out_data.readings[0].x,
         accel_out_data.readings[0].y, accel_out_data.readings[0].z);
   }
