NRFX_TWIM0_INST_IDX' undeclared and configuration problems

[polimarte]

Hi to everyone!

I am working on the SDK 17.0.2 and my project contains nrfx_twim.h functions.

I have a problem to understand the changes that i have to make in the sdk_config.h. I have already read all the posts about these concerns but i found small differences in the sdk_config.h of this SDK that do not let me understand the right updates to make in my case.

Thanks,

polimarte

Hello Polimarte,

i found small differences in the sdk_config.h of this SDK that do not let me understand the right updates to make in my case.

Please elaborate, what small differences have you noticed in the sdk_config? Do you mean, different from previous versions of the nRF5 SDK?

You might be seeing an artifact of the appy_old_config file, which is included in all sdk examples. This file is there to provide backwards compatibility, but its inclusion is perhaps not the most intuitive.
Please take a look at this and this ticket, to see if it may be similar to the problems you are currently experiencing.

Best regards,
Karl

HI, sorry but i cannot understand. that's my fault because i am new to this architecture and i am in seriuos trouble with my project.

For example the first post is referring to set PPI_ENABLED 0 and NRFX_PPI_ENABLED 1. where i can find this macros? i have to add them up manually to the sdk_config.h? i have done it but in apply_old_config there is no change at all.

what am i missing?

The second post suggest to define a custum sdk_config.h. The logic to follow is very different from the previous post that you sent me. 

thanks,

I cant share with you the code through the "insert" function, it gives me an error, maybe because it is too long (4395 lines of code).

If you are unable to paste it with the "Insert-> Code" option, perhaps you could try the "Insert-> Image/Video/File" option instead.

Anyway it is the sdk_config.h that is used in the nRF5_SDK_17.0.2\examples\ant\ant_broadcast\rx\pca10040\s212\arm5_no_packs by default. I am using this example as a template for my project because i have to send data with ANT eventually in the future.

Thank you for clarifying, this makes it a lot easier for me to know what you are working with, great!

Try adding the following to your sdk_config.h file.

Please also make sure that you do not have TWI_ENABLED defined in your sdk_config. To be explicit: It can not be set to 0, it needs to be commented out or removed all together, if you have added it already.

Try this, and let me know if your original NRFX_TWIM0_INST_IDX undeclared error is resolved.
If it is not, please try to share the entire sdk_config file again, so I may take a look.

Looking forward to resolving this issue together!

Best regards,
Karl

Unfortunately the error is still there. The only TWI_ENABLED in my project are these: 

My "new" sdk_config is:

8875.sdk_config.h

As always, thanks Karl!

Sorry, it seems that I enabled TWIM1 in the configuration I sent you, and you are creating an instance for TWIM0.
Please change NRFX_TWIM0_ENABLED to 1, and NRFX_TWIM1_ENABLED to 0, and see if it resolves the error.

It is no problem at all, Polimarte! I hope we will resolve this issue together shortly.

I am happy to hear that the issue is resolved!

I hope you have a great day, Polimarte!

Please do not hesitate to open a new ticket if you should encounter any issues or questions in the future.

Good luck with your development!
