DATASHEET SRF08 PDF
This is the page for the SRF08 Ultrasonic Ranger, with I2C interface. The datasheet can be found from the Rapid Electronics website, or there is a good. The SRF08 Ultrasonic Sensor is an evolutionary step up from the SRF It requires less power to operate, has a longer range (up to 6m) and it performs its own.

Sets the max gain register of the SRF You do not have the correct permissions to perform this operation. You can take advantage of the fact that the SRF08 will not respond to any I2C activity whilst ranging. Note that the relationship between the Gain Register setting and the actual gain is not a linear one.
It also gives a brief flash during the “ping” whilst ranging. There is no easy way to reduce or change the beam width.
If an echo is received within a bytes time slot then it will be set to no-zero, otherwise it will be zero. Location 1 is the onboard light sensor. It is possible to reduce the time the SRF08 listens for an echo, and hence the range, by writing to the range register at location 2.
One long flash followed by a number of shorter flashes indicating its address. Locations 2,3 contain the range of the nearest object converted to inches, cm or uS and is the same as for Ranging Mode. By default, the ranging lasts for 65mS, but can be changed by writing to the range register at location 2. The “Do Not Connect” pin should be left unconnected. Location 4 Location 5 Location 6 Location 7 Locations 8 – 35 0 – mm – mm – mm – mm and so on.

By default, this is 65mS or the equivalent of 11 metres of range. Register 4 Register 5 Register 6 Register You can then read srf088 sonar ratasheet. Write the 3 sequence commands in the correct order followed by the address. The sequence must be sent to the command register at location 0, which means 4 separate write transactions on the Srv08 bus. Working with the networking stack. Locations 2,3 contain the range of the nearest object converted to inches, cm or uS and is the same as for Ranging Mode.
Checking for Completion of Ranging You do not have to use a timer on your own controller to wait for ranging to finish.
Since the ranging can be very short, a new ranging can be initiated as soon as the previous range data has been read.

The default and recommended time for completion of ranging is 65mS, however you can shorten this by writing to the range register before issuing a ranging command. There is more information in the sonar xrf08.
It also gives a brief flash during the “ping” whilst ranging. To be able to fire the SRF08 at a faster rate. If you only wish to get at the range information a bit sooner and will continue to fire the SRF08 at 65ms of slower, then all will be well.
Reads the current temperature. More usefully, 24 0x18 gives a range of 1 metre and 0x8C is 6 metres.
The reading increases as the brightness increases, so you will get a maximum value in bright light and minimum value in darkness. If a location high and low bytes is 0, satasheet there will be no further reading in the rest of the registers. Maximum possible gain is reached after about mm of range. Accept and hide this message. The maximum gain setting is stored datawheet in the CPU’s RAM and is initialized to maximum on power-up, so if you only want do a ranging every 65mS, or longer, you can ignore the Range and Gain Registers.
This is a question which crops up regularly, however there is no easy way to reduce or change the beam width that I’m aware of. If an echo is received within a bytes time slot then it will be set to no-zero, otherwise datasheett will be zero. The default shipped address of the Dtasheet is 0xE0. Take care not to set more than one sonar to the same address, there will be a bus collision and very unpredictable results.

It cannot be read.
Therefore, if you try to read from the SRF08 we use the software revision number a location 0 then you will get 0xFF whilst ranging. They are normally located with the bus master rather than the slaves. Order online now EUR Arranging the data like this should be better for a neural net than the other formats. This is increased at approx.
