hab jetzt folgende einstellung:
define srf08_gain 8 'SRF08 GAIN / DEFAULT = 31'
define srf08_range 255 'SRF08 RANGE / DEFAULT = 255'
und bekomme, wenn ich die hand davor halte, relativ vernünftie werte, jedoch eigentlich andauern Nullen?!!? stimmt die baudrate nicht?!
Hello,
The SRF08 program will NOT work with the SRF10!
That is why my example is called"SRF08 RANGE VIA EMULATED I2C BUS v1.3 for CCIUM2.01 with CCIAB2.0" and NOT "SRF10 RANGE......."
The SRF08 and SRF10 have different registers for reading in the range data
I am working on a program for the SRF10 and I’ll let you know when it is finished.
You can use 2 or more SRF08/10 on one I2C bus.Zitat:
Zitat von gordo
The I2C addresses are changeable but you will need to write a program for this.

when shit hits the fan...... i´m preparing an audio-installation where distances should be measured up to 10meters .. with the srf08 programm, the srf10 works, but measures only 2meters. and it´s really unstable. if there´s anybody in vienna who has a srf08, please contact me!
Hello,
I have created a few beta examples for the SRF10.
One version is for the C-Control I v1.1 and the other for the C-Control I v2.0
I changed the SRF08 example to hopefully work with the SRF10. [-o<
I am not able to test them at this time so let me know how they work. \:D/

P.S. One important thing to know about the SRF08 and SRF10:
If the range between an object and SRFxx is greater than the SRFxx can measure then the SRFxx will return with the range = 0.
thanks for the quick help!!!
i tried it with range 255 und gain 16 and i´m receiving only 40,41 on the serial port (replacing the print to lcd commands to "print range") because i dont have the application board. within 1meter distance i´m getting exact results!
i´m only using ccontrol m unit2.0. for reading data , i´m using hyperterminal with 9600baud, 8databits, no parity, 1stopbit
Hello,
One thing to remember is that the SRFxx’s have a wide range of “View”.
You will probably have to play around with the gain settings and or angle the SRF10 to get the results you want.
Also have a look at -->> http://www.robot-electronics.co.uk/htm/sonar_faq.htm

hmmm. let me think. the sensor is fired into an empty hall. it is 1metre above the ground! no reflections in distance! i think there is some problem with interpreting the data?! maybe i´m getting only the data of the low_register?! ..hmm. i´m not an expert!
Hmmm.
This is interesting.
It could be that the srf10 is detecting the walls, floors, ceiling and or the edges of open or shut doorways, this because of the wide range of "View".
If it is possible, try firing the srf10 outside and see what happens.
Also try adding a pause in between the ranging cycles; it could be that the terminal program can’t handle the amount of data being sent.
I’ll also run thru my examples tonight to see if I made any mistakes.

Hello,
Has anybody had any success using the SRF10 and C-Control I v x.x?
It has become very quiet here. :-s

Ich habe auch nochmal ein SRF10 Bascom Programm für die RN-Control in RN-Wissen reingestellt:

Läßt sich sicherlich leicht auf andere AVR Boards übertragen
