Data Structure and Meaning for RD-03D Radar Module
The data received from the RD-03D radar module consists of a series of bytes that represent different attributes of detected targets. Here’s a breakdown of the typical data structure to help you understand what each byte represents.

Data Frame Structure
A typical data frame from the RD-03D contains several fields that provide information about detected objects. Below is a common structure:

Header (2 bytes): Identifies the start of the data frame.
Length (1 byte): Specifies the total length of the data packet.
Target Count (1 byte): Indicates how many targets are detected.
Targets Data (n * [Data Fields]): Contains information about each detected target.
Checksum (1 byte): Used for data integrity verification.
Example Data Frame Breakdown
Here’s a conceptual example for parsing a data frame:

plaintext

Copy Code
0xFD 0xFC | Length | Target Count | Target 1 Data | Target 2 Data | ... | Checksum
Target Data Fields
Each target's data typically includes the following details:

Distance (2 bytes):
Represents the distance to the target in centimeters.
A value of 0x0001 corresponds to 1 cm.
Speed (2 bytes):
The speed of the target in centimeters per second (cm/s).
A positive value indicates approach, while a negative value indicates retreat.
Angle (2 bytes):
Angle relative to the radar in degrees multiplied by a scaling factor (e.g., 0.1).
For example, a value of 0x01F4 would represent 31.4 degrees.
Width (2 bytes):
Target's physical width in centimeters.
Height (2 bytes):
Target's physical height in centimeters.
Example of Parsed Data
Assuming you receive the following sample data frame:

plaintext

Copy Code
0xFD 0xFC | 0x06 | 0x02 | 0x00 | 0x64 | 0x00 | 0x1E | 0x00 | 0x0A | 0x00 | 0x0C | 0xB4
Interpretation:

Header: 0xFD 0xFC
Length: 0x06 bytes
Target Count: 0x02 (two targets detected)
Target 1:
Distance: 0x0064 (100 cm)
Speed: 0x0001E (30 cm/s)
Angle: 0x000A (1.0 degrees)
Width: 0x000C (12 cm)
Height: 0x00B4 (180 cm)
Checksum: Validates data integrity.

Paintball marker on rotary table. Servo for elevation. Solenoid for trigger.

Wonder if I can get access to Backshed from jail?

Those guys: "We have created a library"

WTF! How are people supposed to learn when everything is pre-packaged.

This is another reason why MMBasic should be the standard for education.
