AttributeError: 'module' object has no attribute 'SpiControl' #3

Closed skylin008 closed 6 years ago

skylin008 commented 6 years ago

I test this code to pyboard,but some error info as follow show:

from LightLora import sx127x from LightLora import spicontrol from LightLora import lorautil l = lorautil.LoraUtil() Traceback (most recent call last): File "", line 1, in File "LightLora/lorautil.py", line 32, in init AttributeError: 'module' object has no attribute 'SpiControl'

How to solve this issue.Thanks!

That uninformative message means (usually) that the SpiControl object didn't construct. You can manually try to create one as in spictrl=spicontrol.SpiControl() and see what message you get... but I just took a look at the pyboard and the SPI interface, not surprisingly is different from the micropython's i'm using.

I don't have a pyboard to test with but looking at the doc you'll need to (a) from pyb import SPI (b) init it differently (see spicontrol.py line 17) and (c) use send_recv and send instead of write and write_readinto. And... the Pin definition is different - which affects spicontrol and the irq handling in sx127x.py.

I don't currently have plans to get a pyboard.

Thanks kindly supported .Yes.I had modified the GPIO define to be used the pyboard hardware SPI interface. I want to porting the sx127x driver to pyboard and reaiability testing.Thanks!

You're welcome. Good luck.
