I switched to that and can now read the sensor using gpio. If you have left the pullups on both boards, I suggest you remove them if you can. I tried with another i2c device. 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. I'm using the 3.3V version of the MLX90614. In that post, he's using a similar sensor, MCP9808, which is an I2C temperature sensor and he's using the XDK IoT Edition. I’m running Ubuntu 16.04. // It has been modified to take one parameter indicating. // Originally, 'endTransmission' was an f(void) function. With a logig analyzer or oscilloscope you could test the content of the signals in SCL and SDA. Oh and the example is for the arduino extension board. If you are true, this could be something more difficult to fix. But, sudo i2cdetect -y 1 does not work just the same. However, when running: i2cdetect -y -r 1 I see no devices. 3. Thank you ill try this but give it little chance as even the i2cdetect doesnt find it. The problem still remains. This did not work. I see the search (i2cdetect) showing up on the bus but see no response. On Arduino Uno all works fine. Setup: uboot and Kernel from TI SDK v7. I would suggest you to try this, and let us know the results. 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. Still would like to hear about a solution using i2cc. Raspberry Pi: PIGPIO not detecting I2C device but i2cdetect -y 1 detects it and I can even run my codes well in SMBUSHelpful? As far as I know, i2cdetect can detect hadrware before it is used by the kernel driver. Raspberry Pi: Why i2cdetect slave can not detect polling way but interrupt can?Helpful? 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. Right, the i2cdetect printing above is *after* adding the correct lines in the board file. Started by Shakipu, July 06, 2014, 06:39:33 pm. 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. 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. Bupi, I have the rev2 of the BMP180. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. 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. I am having a problem with my Beaglebone black interfacing with a BH1750 light sensor (am using a breakout board). 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. Am I right? I attached the temperature sensor using the same hardware setup to an Arduino and there the device is also recognized. Although I would like to stay with a digital solution, my current plan is to change the sensor to pwm mode. About the "repeated start I2C" support, I will investigate this so I can give you a proper response. With this we could check point-2. Are you using a voltage level converter to use the MLX90614? What could be the possible reason for the same? I'm not using that one. Sometimes, I get this on the i2c-1 : On which bus did you connect your i2c devices ? I could easily get other devices, including this one to work. Depending on the version of the Raspberry Pi, the control is different. Have you been able to use the sensor? 3. Could you check the signals between the sensor and the board? Thanks for the help so far. Raspberry Pi: GY-521 module / MPU-6050 3x Accelerometer not detected by i2cdetectHelpful? Please note that this command differs if you are using the very first Raspberry Pi. However the speed is still 300khz. Thank you anyway. It also works fine on my 3.3V arduino fio. The python link in the example no longer works, unfortunately. 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 … Sorry for the late reply. 2. Do I need something for the Edison? I have a jetson nano and jetson TX2. sudo i2cdetect … You most likely already checked this but just in case: The MOD-BMP085 from Olimex uses pullups too. Have you followed the previous steps that Zahid posted? For older models, run. The problem: When i use DVP software all fine. Which I connected to the i2c breakout from sparkfun: https://learn.sparkfun.com/tutorials/sparkfun-blocks-for-intel-edison---i2c-breakout-block SparkFun Blocks for Intel® Edison - I2C Breakout Block - learn.sparkfun.com. These all work well. I’ve hooked up two different IMUs to the … It seems that from some reason it did not succeeded. Thanks for the advice. but ADRREES 0x68 haven't been detected … Hopefully this can solve the issue. Raspberry Pi: Raspberry Pi not detecting MPU6050 with i2cdetectHelpful? Detect all the current devices connected to your Raspberry Pi by running the following command. I am wondering if the problem is the RTC that I have installed. I had the same result. I was looking at that thread and you already posted your question, but apparently this flag was already enabled in your kernel. The case is however different. I enabled the i2c interface in Raspi-config, and added the “dtparam=i2c_arm=on” line to /boot/config.txt as per the docs. I followed section 2 of the instructions. Also, are you testing the signals?
