Hi, Jetson nano’s I2C dose not connect the ADS1115.
When I use the ‘i2cdetect -r -y 0’, it is Ok but library of ADS1115 is not operating.
I get error messages that " Could not determine default I2C bus for platform."
so i change the address to 0x40 bus failed and i get another error.
library is here “GitHub - adafruit/Adafruit_Python_ADS1x15: Python code to use the ADS1015 and ADS1115 analog to digital converters with a Raspberry Pi or BeagleBone black.” (simplytest.py)
Can i2cget/i2cset utils worked?
Hi, @ShaneCCC. Thank your answer.
i2cget/i2cset is not worked.
i2cdetect -l don’t show ADS device.
ADS device is okay. i tried on arduino.
Hi, @Trumany !
this file is not downloaded with “File Not Found or Link has Expired”.
Please search “40-pin” in DLC.
You mean change the AR and AS of I2C(SDA and SCL). Is right?
There are two I2C ports on the 40-pin header, I2C0 and I2C1. Both are 3.3v voltage level. You should check your device to make sure which I2C is attached to and what the voltage level is.
I checked this document but no problem
I tried PCA8695. this module is available through I2C.
ADS1115 has pull up. Is this problem? (because i2c has pull up too.)
What’s the pull-up voltage level? There is 3.3v pull-up inside the module. Did you use a oscilloscope to observe the waveform of I2C data/clk to make sure the communication is correct?
Yes, i can get the waveform of I2C data/clk.
pull-up of ADS1115 is 3.3v (PCA9685 is 3.3v too.)
I2C works very Well. (i tried PCA 9685)
There is problem using ADS1115. (I tried ADS1115 on arduino, no prolem.)
Good news, can you tell how you solve it?
