Detailed Description

Used for iterating over the data frames via the sensor_decoder_api.

Example usage:

(.c)
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);
}
static int sensor_decode(struct sensor_decode_context *ctx, void *out, uint16_t max_count)
Decode N frames using a sensor_decode_context.
