| |
| I use it to drive the SRF08 ultrasonic ranging module |
| for use with Free Fall night parachute landing |
| where i MUST know the distance from ground in order to land safely. |
| Infrared goggles gives you an idea about the drop zone |
| but you cannot judje the precise distance from the ground due to |
| optics distortion. |
| For programming example see the SRF08 module code. |
| |
| CAUTION: THIS IS A TEST PROGRAM. DO NOT USE IT FOR PARACHUTE LANDING!!! |
| There are too many thing missing from the code like |
| audio and visual alerts, height averaging, variable gain, |
| variable range settings and many other safety features |
| needed to make it suitable for this task! |
| I can experiment because it is my life! |
| Its only purpose is to give an idea of how to use the driver code. |
| |
| I hope it can help someone. |
