'_SPI_OPCODE_RDID' is not defined (Jetson Nano) #12
Comments
|
thats odd because its defined right above |
|
@ladyada Just tried one on a feather_nrf5280_express -- no problem. |
|
I haven't used it recently. Perhaps this is something related specifically to the Jetson Nano. |
|
@ADV-LUT how are you installing? what version python are you running |
|
@ladyada I have python version 3.6.8 I am grateful for any help. |

It might be a slight syntax error? Need to add a Simple example to demonstrate issue: class Foo:
_SOME_VAR = 23
def foo(self):
return bytearray([_SOME_VAR])and then: $ python3

That makes sense. |
|
@ADV-LUT please try the example code as is |
|
I have the same result/issue as @caternuson with the sample code on the Jetson Nano. And how can I fix that? |
|
@ADV-LUT Do you know how to make pull requests? This looks like a pretty simple issue that would make for a good first one. |
|
@caternuson I have not made a pull request yet, but I would like to do it. I've just read how it works, but have not quite understood. And if I understand that correctly, the pull request is there for me, that my changes are taken over in the repository. But I do not know, where I have to do changes. |

I am running similar issue on Raspberry Pi. name '_SPI_OPCODE_RDID' is not defined Thanks! pi@raspberrypi:~ $ python3

By the way, it worked on M0 Express and Windows 10.

@caternuson I don't think this has to do with const. const should just return the same value. I think this is a slight difference in name lookup between CPython and CircuitPython. I think #12 (comment) is exactly right. I'm not sure why it was closed and not fixed. |

I'm not finding a way to allow use of class level This shoulnd't work, but does: class Foo:
_SOME_VAR = const(23)
def __init__(self):
print(_SOME_VAR)Adafruit CircuitPython 5.3.1 on 2020-07-13; Adafruit ItsyBitsy M0 Express with samd21g18
>>> import foo
>>> f = foo.Foo()
23
>>>While this: class Foo:
_SOME_VAR = const(23)
def __init__(self):
print(Foo._SOME_VAR)leads to this: Adafruit CircuitPython 5.3.1 on 2020-07-13; Adafruit ItsyBitsy M0 Express with samd21g18
>>> import foo
>>> f = foo.Foo()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "foo.py", line 6, in __init__
AttributeError: type object 'Foo' has no attribute '_SOME_VAR'
>>> Removing use of class Foo:
_SOME_VAR = 23

>>> import foo

23

@caternuson Thanks for the experiments. Removing the const is the best option. In general, it is overused and should only be used at the top level. |
|
This should be fixed by #22. Please try the 1.3.4 version of the library: |

Closing for now. Can reopen if needed. |
I'm trying to run the SPI fram breakout board with the Jetson nano and always get the following error message when I'm running the example.
