URM37 V3.2 not working
Portugal 2013-07-11 02:52:29 13831 Views19 Replies Hi everyone,
I have just bought a URM37 V3.2 sensor but unfortunately it is not working. The context is the following one:
Arduino MEGA 2560
Sensor URM37 V3.2 (TTL mode). Pin 9 connected to pin 6 of Arduino. Pin 8 connected to pin 7 of Arduino
The code I am using is the one provided by DFROBOT (I did not change it, just copy and paste):

The output is always the same: TIMEOUT. So basically, I get no value.

2013-10-31 11:14:37 Hello,
Sorry for bringing up an old post, but today I started using a URM37 V3.2 for a school project.
The only problem I encounter is, I'm not getting any information out of it.
I've use the library from Lauren which I managed to get from this website.
This gave me timeout errors.
After that I used the code you (Jose) provided, but that didn't work out either.
The terminal shows the following:
[img]http://img69.imageshack.us/img69/6530/5u5k.png[/img]
One thing that I am sure of is the wiring. I'm using this:

Thanks in advance,

Hi Portugal!
Tudo bem?
Take a look at this:
[url=http://arduino.cc/en/Reference/SoftwareSerial]http://arduino.cc/en/Reference/SoftwareSerial[/url]
That is what you want to use if you want to change the Serial port on a Arduino. Give it a go, if you have any problems, paste your code here.
I think my Portuguese is better than my Chinese :P But I am quite surprised! Have you studied Chinese?
Cheers^^

This will not work if you have something connected to Rx Tx pins from Arduino. It blocks communcation with Arduino. So you have to unplug it when you want to upload.

Hi Jose,
in order to use this code and ports 3 and 2, what must I change on the code? Using ports 1 and 0 is not a good options as it blocks the communication between the PC and the Arduino. Portugal

This will not work if you have something connected to Rx Tx pins from Arduino. It blocks communcation with Arduino. So you have to unplug it when you want to upload.

Sensor: URM37 V3.2 (the green led on the back of the board is constantly on), TTL Mode and only 4 pins connected: pin 9 (TX), 8 (RX), 2 (GND) and 1 (VCC).

Sensor's pin 2 connected to gnd
code: urm.begin(0,1,9600);
When I try to upload the code, I always get a timeout communicating with the programmer. Therefore, the code is not uploaded.
------------------------------------------------------------------------------------------------------------------------
Third Experience:
------------------------------------------------------------------------------------------------------------------------
Sensor's pin 9 connected to pin 2
Sensor's pin 8 connected to pin 1
Sensor's pin 1 connected to +5v
Sensor's pin 2 connected to gnd
code: urm.begin(2,1,9600);
The output of the "urm.requestMeasurementOrTimeout(DISTANCE, value)" is always TIMEOUT.
------------------------------------------------------------------------------------------------------------------------
I hope you find the problem through this description.

Did you connect pin 1 and pin 2 as well ?
Make sure there is a green LED on the back turned on
Cheers Jose

Jose 2013-07-11 02:52:29 Hi everyone,
I have just bought a URM37 V3.2 sensor but unfortunately it is not working. The context is the following one:
Arduino MEGA 2560
Sensor URM37 V3.2 (TTL mode). Pin 9 connected to pin 6 of Arduino. Pin 8 connected to pin 7 of Arduino
The code I am using is the one provided by DFROBOT (I did not change it, just copy and paste):

}
The output is always the same: TIMEOUT. So basically, I get no value.
Can anyone help on this issue?
