Jeff,
If you go to the 2nd page of the link you provided, you will find my conversion of the "ping dar((( - a radar type disply".· I have also attached my spin program for a boe bot I built about a...

Campeck,

Get a prop proto board and try this program.· Prop is a lot faster.

All,

Working CCNA certification.· Wish I had more time for Prop projects.· Merry Christmas.

I have been looking at this sensor with great interest.· I noticed that the HM55B is on sale.· Is the HMC6352 on sale as well?· Thanks and Happy Turkey Day All.

Istvan,
Nice Object.· Got a chance to look at it last night.· I will certainly use it, from this point forward, for all future ·Math functions.· Have a good one.

Here is a project that you might be able to manipulate.· It is written in BS2.· Good luck.

HSS,
Here is an example of using FP math to manipulate the sin table.· If you wish to display a FP value on PST, you must convert any FP value to a string.· Pay close attention to the "attached"...

Not sure if this is what you are looking for, but attached program converts a "degrees" value (and range), to coordinates (X,Y) value, using the sin table.· Understand that this DOES NOT USE FLOTING...

Would an optocoupler work in this case??? Plus separate PS???...

Very aggressive project to say the least.· Would it be practical??? Don't know.· If you are still interested in a complicated detection system such as this, using Doppler techniques might be harder...

Thanks for the info!!! Wanted to respond earlier, but MAN, a working weekend and cleaning up after the big storm·last weekend kinda took all my "fun" time.· Anyway, I have some time tonight to...

Bill Henning,

Don't mean to hijack the thread but just had a quick question.· Your LMM technique allows you to access memory above 32K.· That' great.· I have a prop proto board.· As you know, it...

Jamming can be tricky.· A jammer has·a power advantage·over a radar (or sensor).··The signal·only has to travel one-way.· The·radar has to send the pulse,·and wait for·the echo to return to the radar...

Certainly, under normal circumstances, you would want to remove all forms of interference.· I just want to satisfy my own curiosity... just to see if I get the same results as when I worked on ECM...

NONAMEHERO,
It is absolutely possible to jam a sensor, if the jamming signal is centered on the same frequency.· In Electronic Counter Measures (ECM) jargon, this is called Spot On Noise (or just...
