Are you a programming guru?

[kel]

i have built a an pool object detector in analogue/hardware and would like to take it further to develop it in software.i'm very new to picc/c programming.
the device is to have set two setpoints,one for the minimum and maximum.the echoes received are integrated and a smooth rising signal is obtained from this result.
the signal changes in amplitude depending on the mass of the object that is in the pool.any idea on how i should go about this in software?
i beleive some programmers/gurus are in this forum..
cheers

Perhaps you should be looking at a dsPIC?

Your description of the pool detector is rather simplistic and I assume there is significantly more to your existing analog implementation than you have described. For example the return echo in the event of a disturbance will be determined by several significant criteria. This includes:

The mass and velocity of the object.
The shape of the object
The angle the object penetrates the surface
The distance of the source of the disturbance from the sensor (attenuation)
Surface noise in the presence of wind
Water temperature
Barometric pressure
Depth of the pool
3D shape of the pool
Water level
Water salinity (salt water versus fresh water chlorination system)
Pool filtration system and characteristics

Taking all this into account, it is not easy to answer your question.

There are so many answers to your question, that I would ask a couple question of my own.
- How much analog stuff do you want to replace with a PIC?
- Are you looking to do DSP with a PIC?
