New submission from John Brearley <brear...@bell.net>:
The first attached script ada_dbg1.py.txt which uses simple hardcoded import statements, the creation of ads1115 objects work fine. The second attached script ada_dbg2.py.txt uses a loop to import a variable list of packages, which allows for more graceful error handling & messaging. globals()[pkg_trunc] = importlib.import_module(pkg_trunc) The high level observation is that board, busio & adafruit_extended_bus objects continue to be correctly created after the import loop is done. Its just adafruit_ads1x15.ads1115 that does not like this import method. The same line of code creating ads10 gets error: Traceback (most recent call last): File "ada_dbg2.py", line 33, in ads10 = adafruit_ads1x15.ads1115.ADS1115(i2c_1, address=0x48) AttributeError: module 'adafruit_ads1x15' has no attribute 'ads1115' When I look at the global variables, from ads_dbg1.py, I see: 'adafruit_ads1x15': <module 'adafruit_ads1x15' from '/home/pi/.local/lib/python3.7/site-packages/adafruit_ads1x15/init.py'>, When I look at the global variables, from ads_dbg2.py, I see: 'adafruit_ads1x15.ads1115': <module 'adafruit_ads1x15.ads1115' from '/home/pi/.local/lib/python3.7/site-packages/adafruit_ads1x15/ads1115.py'>, So I tried doing the import without the .ads1115 appended, & got: 'adafruit_ads1x15': <module 'adafruit_ads1x15' from '/home/pi/.local/lib/python3.7/site-packages/adafruit_ads1x15/init.py'>, But I still get an error. Traceback (most recent call last): File "ada_dbg2.py", line 33, in ads10 = adafruit_ads1x15.ads1115.ADS1115(i2c_1, address=0x48) AttributeError: module 'adafruit_ads1x15' has no attribute 'ads1115' I went through all 8 permutations of with/without the .ads1115 in the importlib.import_module statement, no luck.
