When I open the mode file in VI it reads std. Besides, It would not solve my problem as I'm trying to read it from Node.js. Raspberry Pi: Why i2cdetect slave can not detect polling way but interrupt can?Helpful? I2C bus 0 and 1 do not detect connected devices. OLinuXino Android / Linux boards and System On Modules, [SOLVED] i2cdetect doesn't detect anything, https://www.olimex.com/forum/index.php?topic=2866.0, Quote from: Shakipu on July 07, 2014, 08:48:46 am, Quote from: Shakipu on July 08, 2014, 07:40:26 pm. Depending on the version of the Raspberry Pi, the control is different. I tried with another i2c device. Did you try with the suggestions above? No PMs please, they dont get answered. sudo i2cdetect … But, sudo i2cdetect -y 1 does not work just the same. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I wrote a simple app to publish the sensor readings to the console. 2. I tried with another i2c device. try ./i2cdetect from the folder where i2cdetect binary is stored. If you are true, this could be something more difficult to fix. Hello everyone, I am trying to use the Arduino UNO rev 3 with tIIC 1602 LiquidCrystal Display. You can check the I2C … I cannot send a start command to the sensor, so I see no response from the sensor. Are you using a voltage level converter to use the MLX90614? I am pretty certain that is why it's not working. I am using the Arduino IDE 1.7 on Windows 10. https://learn.sparkfun.com/tutorials/sparkfun-blocks-for-intel-edison---i2c-breakout-block?_ga=1.243... https://github.com/MakersTeam/Edison/blob/master/Python-Examples/Basics/I2Ctest.py, https://m2aglabs.com/2015/02/24/intel-edison-and-i2c-sensors-with-xdk/. https://learn.adafruit.com/using-melexis-mlx90614-non-contact-sensors/wiring-and-test, https://learn.sparkfun.com/tutorials/sparkfun-blocks-for-intel-edison---i2c-breakout-block. These all work well. It is a 16x2 LCD display with a I2C backpanel. The sensor is not compatible with 300khz, only 100. I was looking at that thread and you already posted your question, but apparently this flag was already enabled in your kernel. I see the search (i2cdetect) showing up on the bus but see no response. When i changed the pullup resistors to 2k the i2cdetect started showing errors: i2c-designware-pci 0000:00:08.0: i2c_dw_handle_tx_abort: lost arbitration.I am quite sure the problem is with the repeated start for now. Setup: uboot and Kernel from TI SDK v7. Shakipu, your result of i2cdetect on i2c-1 is normal. As far as I know, i2cdetect can detect hadrware before it is used by the kernel driver. It outputs a table with the list of detected devices on the … I can not send anything to the sensor in order to start. The problem still remains. For more complete information about compiler optimizations, see our Optimization Notice. This address is shown. Teams. Bupi, I have the rev2 of the BMP180. Detect all the current devices connected to your Raspberry Pi by running the following command. Started by Shakipu, July 06, 2014, 06:39:33 pm. Could you check the signals between the sensor and the board? For the original Pi, use the command below. I followed section 2 of the instructions. Arago distribution thanks very much,that seems some problem of the pin function select of gpio,when i use devmem0xF80007C0 ,it shows 0x00001601 that means i2c funtion is not avaliable ,so i set the value to 0x00001641,then set i2c detect -r 0, it's not get timeout result but xi2cps e0005000.ps7-i2c: Retries completed, exit . Ok, I was just wondering why these addresses were showing some times and some times not. The python link in the example no longer works, unfortunately. I'm using the IR Temperature Sensor from Adafruit (MLX90614) : https://learn.adafruit.com/using-melexis-mlx90614-non-contact-sensors/wiring-and-test Wiring and Test | Using Melexis MLX90614 Non-Contact Sensors | Adafruit Learning System. 2. For older models, run. The i2cdetect command lets you know the device address on the i2c bus. This strongly suggests that there is a chip at this address. I am wondering if the problem is the RTC that I have installed. Oh and the example is for the arduino extension board. I’ve hooked up two different IMUs to the … Provided by: i2c-tools_3.1.0-2_amd64 NAME i2cdetect - detect I2C chips SYNOPSIS i2cdetect [-y] [-a] [-q|-r] i2cbus [first last] i2cdetect-F i2cbus i2cdetect-V i2cdetect-l DESCRIPTION i2cdetect is a userspace program to scan an I2C bus for devices.

According to the Wire.h library, which can be found under /AppData/Roaming/Arduino15/packages/Intel/hardware/i686/1.6.2+1.0/libraries/Wire/src, a repeated start can be enabled. but ADRREES 0x68 haven't been detected … Still would like to hear about a solution using i2cc. i2cdetect is not in the path. When I connect, via wire, the light sensor to the 3.3 volt (p9 port 3) and the ground (p9 port 1) as well as the clock and data (p9 port 19 and 20), the beaglebone is not able to detect the light sensor at the … I enabled the i2c interface in Raspi-config, and added the “dtparam=i2c_arm=on” line to /boot/config.txt as per the docs. If it lights up, flashes, or otherwise shows any activity when you apply power, that's a good sign. . Provided by: i2c-tools_4.0-2_amd64 NAME i2cdetect - detect I2C chips SYNOPSIS i2cdetect [-y] [-a] [-q|-r] i2cbus [first last] i2cdetect-F i2cbus i2cdetect-V i2cdetect-l DESCRIPTION i2cdetect is a userspace program to scan an I2C bus for devices. Thank you anyway. 3. \$\begingroup\$ It looks like a pretty simple module, so I'm not sure if there's an obvious way. The implementation of uint8_t TwoWire::endTransmission(uint8_t sendStop) for false condition states: If we go by the description, adding a Wire.endTransmission(false) should enable a repeated start. Do you have updates on this? Read the documentation? It outputs a table with the list of detected devices on the specified bus. Thank you for the reply. It looks like it already has a level shifter. In my belief, if one i2c device works all should work, I wonder if it can possibly be some kind of compatibility issue? This should be it: https://github.com/MakersTeam/Edison/blob/master/Python-Examples/Basics/I2Ctest.py https://github.com/MakersTeam/Edison/blob/master/Python-Examples/Basics/I2Ctest.py. Probing was skipped, because this address is currently in use by a driver. I tried with the Arduino MLX library on the edison but only wrong values were read (same as when sensor was disconnected). // It has been modified to take one parameter indicating. One more thing is i2cdetect will need some parameters like which bus etc. “sudo: i2cdetect: command not found” is the result. Have you checked this link https://m2aglabs.com/2015/02/24/intel-edison-and-i2c-sensors-with-xdk/ https://m2aglabs.com/2015/02/24/intel-edison-and-i2c-sensors-with-xdk/. Do you have updates with the MLX90614? Thanks for the help so far. However, when running: i2cdetect -y -r 1 I see no devices. As mentioned, I use the i2c block with a couple other i2c sensors. 1. I switched to that and can now read the sensor using gpio. I tried to plug only the tsl2561 but I got nothing on my i2c buses. As you put it in your first post, a compatibility issue is also possible. The addresses that you see are referred to the EEPROM T24C16BN-SH, and that's good because means that the i2c port works. Thank you ill try this but give it little chance as even the i2cdetect doesnt find it. Raspberry Pi: PIGPIO not detecting I2C device but i2cdetect -y 1 detects it and I can even run my codes well in SMBUSHelpful? I would suggest you to check the connection that he's implementing in there and see if there's something that you haven't done with your configuration. Please note that this command differs if you are using the very first Raspberry Pi. Are you using the same library that is being used in that configuration? // Originally, 'endTransmission' was an f(void) function. The sensor is not showing up. Any ideas on how to use the sensor on the edison? I assume i'm missing something in the setup ... just not sure what that is. I had the same result. Any ideas on how to get this sensor to work? I'm using the sparkfun i2c block only. Thanks for the advice. However, when running: i2cdetect -y -r 1 I see no devices. About the link that you shared, are you following all the instructions from there? I attached the temperature sensor using the same hardware setup to an Arduino and there the device is also recognized. Sorry for the late reply. In the end i struggled so long with this sensor. Have you followed the previous steps that Zahid posted? About the "repeated start I2C" support, I will investigate this so I can give you a proper response. Raspberry Pi: GY-521 module / MPU-6050 3x Accelerometer not detected by i2cdetectHelpful? Do I need something for the Edison? I also have the ADC block connected, an accelero to the i2c and another temperature sensor to the i2c. The sensor works with a photon but not … But we'll investigate this to see if we can find an answer. sudo i2cdetect -y 1. sudo i2cdetect -y 1. You most likely already checked this but just in case: The MOD-BMP085 from Olimex uses pullups too. "UU". I'm not using that one. I have a SHT31 temp/humidity sensor attached to the i2c pins of a raspberrypi. Am I right? Would be great if you could help on that! When I scope the signal on the I2c i still see a clock rate of 300 khz. The i2c bus connects up to 255 devices. I could change the mode but after startup it would return to fast and would always should fast on my scope. On Arduino Uno all works fine. It seems that from some reason it did not succeeded. Does anyone have a copy of this? Take a look at this thread: , Diego posted a code you can use to check if there is a device connected. This address is shown. With this we could check point-2. I was following the jetson hacks to connect an adafruit 10 DOF IMU to the jetson tx2 when qtcreator building RTIMULIB demo didn’t detect a connected IMU. I'm using the i2c sparkfun block https://learn.sparkfun.com/tutorials/sparkfun-blocks-for-intel-edison---i2c-breakout-block?_ga=1.243... SparkFun Blocks for Intel® Edison - I2C Breakout Block - learn.sparkfun.com from which i conclude the level shifter is already on board? The mlx is using a slightly altered version of i2c (repeated start). Hopefully this can solve the issue. Unable to detect sensors on with i2cdetect. The data is published, but there is no data (nan) from the sensor. These all work well. Do you gave pullup resistors on the external boards you are trying to use? If you have left the pullups on both boards, I suggest you remove them if you can. Just remember: 512M Pi's … It also works fine on my 3.3V arduino fio. There is then nothing to measure right? The problem: When i use DVP software all fine. 2. If an I 2 C device is detectable with i2cdetect, it means hardware is fine and if not detectable means some issue with the hardware. sudo i2cdetect … It came without any instructions of it’s own and other people are having trouble using a RTC on the Pi2. 1. Have you been able to use the sensor? If the I2C scanner does not detect the PCF8574 that is on the backpack, then either its faulty or you wired it wrong. As the A20 has them already, it now works fine. The sensor had a pwm mode. I just wandered why i2cdetect did not detect anything before doing that. While the modern Pi’s use port 1, the original used port 0. However the speed is still 300khz. Will try tomorrow. 3. The case is however different. For Pi 3 and Pi 2 (models A, B, B +) and Pi Zero, run. Thanks for the efforts. I am connecting the Philips PCF8574P IO expander on I2C1 and it is detected on running the command: i2cdetect -r -y 1. Sometimes, I get this on the i2c-1 : On which bus did you connect your i2c devices ? Any ideas? 3. When i connect my Jetson Nano I2C bus to I2C headers on Eval board i can't detect the chip through the i2cdetect utility on the jetson nano. Re: i2cdetect doesn't detect anything July 09, 2014, 08:07:31 pm #14 Ok, I was just wondering why these addresses were showing some times and some times not. On arduino UNO I connect it to 3.3V gnd, sda and scl and works well. This did not work. i2cdetect is a powerful and simple tool for figuring out I 2 C devices. I have a jetson nano and jetson TX2. I could easily get other devices, including this one to work. Check the device address with i2cdetect. What could be the possible reason for the same? Another problem may be i2cdetect is not having executable attribute (highly unlikely that it will be so). I’m running Ubuntu 16.04. My board here had pullups on it for a RTC and I could not get it to work until I removed them from the board. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. I'm using the 3.3V version of the MLX90614. Just to know that the problem is not the block. I tried changing the mode from fast to standard as recommended in this thread. Have you tried to attach the sensor to a level shifter and then to the Edison Module? Has you tested the SparkFun Block? I am having a problem with my Beaglebone black interfacing with a BH1750 light sensor (am using a breakout board). Raspberry Pi: Raspberry Pi not detecting MPU6050 with i2cdetectHelpful? I cannot see how fidling with the wiring on the display side will help, if the PCF8574 is not responding, solve and deal with with that problem first. Executing i2cdetect may need root privileges and can be used as follows: With a logig analyzer or oscilloscope you could test the content of the signals in SCL and SDA. When I connect the TCA9535 I2C IO expander to the BBB it does not detect the same. Right, the i2cdetect printing above is *after* adding the correct lines in the board file. Q&A for Work. In that post, he's using a similar sensor, MCP9808, which is an I2C temperature sensor and he's using the XDK IoT Edition. Also, are you testing the signals? 1. I do however need an IR temp sensor and this is by far the best one. I would suggest you to try this, and let us know the results. All i2c (actually smbus) advice is welcome. Quite sure the problem is there. And the debugging could proceed accordingly. sudo i2cdetect -y 0 The Raspberry Pi designers swapped over I2C ports between board releases.
