Hey Frank,
So where exactly did you buy your 'problem' from? I got an email two minutes ago saying that mine is on my way (ordered earlier today from ebay) and I just want to check I chose a different supplier to you!!

Hi White Wizzard,
I bought it from a german distributer over EBAY (chipabuy_de) in Hagen. It looks like exact as all the others HC-SR04 but it doesn't work satisfying with our new command and the characteristics are not so as described in the gettable documents...

Hi plasma,
I used the description from beta 8 for my IR-test. It works very fine! I used the TSOP34136, 36kHz from pollin.de for the test. This device work from 2.7 to 5.5V.
This IR-command is a great enrichment!!! I want to build a little hexpod roboter with IR-control...

Hi White Wizzard,
does your ultrasonic sensor work as expected?
I am helpless with my two sensors...

after moving the pins to 15 and 16 i got good results with pause 120.
but moving in a distance under 5.1 cm it comes the transducer not responding error.
ill guess it is to near.

@Plasma:
Thanks a lot for your test! I will try to filter/better regulate my 5V and try my tests again.
@White Wizzard:
I am very impatient to your result!

Hi Frank,
Just fired up a test rig for my one Ultrasonic module. No fancy software, just trying a Distance command in a loop pausing 1 second between reads.
This is set up on my 44-pin PIC TQFP MicroMite Module and have tried three so far all with same result. Using Pin 1 (Trig) & Pin 2 (Echo) driving Ultrasonic module at 5v.
I get two random values displayed 0.0562089 & 0.0449671.
These don't seem to have any pattern to them and not related to an object placed in front of the sensors.
So at this moment I am in same position as you.
I will get my Logic Analyser out and carry out some more detailed troubleshooting.
Speak soon . . . .

Has anyone out there got the UltraSonic Module working on Beta 8 or Beta 10??.
If so please confirm:
- Beta version
- Driving voltage
- any pull ups
- Pins used for Trig & Echo
- Code snippet used
- PIC device 28/44pin; MX150/MX250
plus any other info
Thanks for any replies . . . .

Beta 8
5,1 volt from Palm Pre Handy Loader
no pull ups
pin 15 & 16
15 - trigger
16 - echo
28 pin pic32mx 150f128
15 cm wires lenght
the next code runs 7 h with correct distance
40 Mhz
iam shure a 5 volt tolerant Pin is needed for echo / trigg
Pause 100
Do
Pause 85
range = Distance (15,16)
print int(range)
pause 85
loop
the splittet pause isnt really needed its a rest from a test , this code works 100% here.
if the pause too small it maybe works ,but if you move an object in the Range really fast over a long distance you get the error from above .
hope this help

Thanks Plasma,
As you were writing this I managed to get success.
It looks like the GND connection requires connecting first to the U/S module otherwise I randomly get strange results?
So Im on Beta 10, 44pin MX150 Pin 1 (trig) Pin 2 (echo) at 5v driving (GND CONNECTED FIRST!!)
Works very well now.
And now I can't get it not to work at all - something strange going on here making it difficult to fault find.
If I point to open space I get the -1 value as documented by Geoff. The program then stops saying 'Transducer not responding'. If you then bring something into range again, I keep getting the same 'Transducer not responding' message (and program crashes out) for a random number of times. Then suddenly all works ok again until open space once more.
Plasma{/B] Can you check what happens with your module if pointed to open space (i.e. no object in range)
THANKS
