Remote I/O error #9

Open butlerjoey opened 5 years ago

butlerjoey commented 5 years ago

I'm just trying to run the simple test code, but keep getting the error message below. I know the Lidar Lite and Pi are setup correctly, and I've turned on the I2C interface and enabled the I2C tools. I'm new to this, and have been stuck here for quite a while now. Any idea what might be wrong?

Traceback (most recent call last): File "/home/pi/Lidar-Lite/python/test.py", line 9, in print (lidar.getDistance()) File "/home/pi/Lidar-Lite/python/lidar_lite.py", line 38, in getDistance self.writeAndWait(self.distWriteReg, self.distWriteVal) File "/home/pi/Lidar-Lite/python/lidar_lite.py", line 24, in writeAndWait self.bus.write_byte_data(self.address, register, value); OSError: [Errno 121] Remote I/O error

Can you do a bit of debugging here? Are you sure that the device is connected properly? Can you confirm this by checking "sudo i2cdetect -y 1" to see that the device is recognized on that address?
