Re: [riot-devel] Status of the MRF24J40 radio module support

[Peter Kietzmann]

Hi Neo,

the PR was closed because it was outdated but Tobias Fredersdorf 
promised to open a new one with more up to date code -> so there is more 
code but not available until now. I will meet him f2f in the next week 
and report the status, in case there is no PR to await soon.


At the RIOT summit several people stated their interest and we agreed on 
blocking that work about two more weeks for Tobias. In case there is no 
progress, someone else will take this over (probably me).


Which hints do you have about hardware access?

And who is Frederic? At least I'm not aware to be his follower.

Best regards
Peter

Hello developers,
in the comments of the Pull-Request 5099 it seems that Tobias
Fredersdorf stops now his efford in implementing the MRF24J40 driver.
What is the status of the MRF24J40 driver development? Is there more
code available as stored in GitHub?
If not - I have some additional important hints about that driver
(depending especially the hardware access of this radio chip).
Who will be the follower of Frederic? Is it Peter Kietzmann?

Re: [riot-devel] ADC on SAMR21-xpro (Alessandro Nicoli)

[ALESSANDRO NICOLI]

Hi Peter,

Yes, i've used the last configuration that you posted (as you suggested me
last time).
I tried to use the pin PA06, but i can't be able to read different values
but 1206 (or similar).

For the test, i've used a simple analog potentiometer plugged to PA06.


*best regards, *

Re: [riot-devel] ADC on SAMR21-xpro

[Peter Kietzmann]

Hi Alessandro,

what is your code base? If you have adapted this PR (as I proposed some 
time ago)


https://github.com/RIOT-OS/RIOT/pull/4162/

it should be PA6, PA7, PA8, PA9, PB2, PB3 according to the ADC channel. 
Compare this configuration:


https://github.com/RIOT-OS/RIOT/pull/4162/files#diff-134bda29ded96fa4abaa9f99216a6116R325

Hi Rioters,
I've some troubles about using the ADC on the SAMR21-XPRO board.
At now, i've added the libraries and required features for it, it
compiles and i can use the "periph_adc" test, but i'm not able to find
which GPIO are used for the ADC.

In less words, i need an help to start using the ADC lines for a
moisture sensor.

I've found the watr-li tutorial (http://watr.li/Sensing-moisture.html),
but is deprecated.

There is someone who can drive me about it?


Thanks a lot,

[riot-devel] ADC on SAMR21-xpro

[ALESSANDRO NICOLI]

Hi Rioters,
I've some troubles about using the ADC on the SAMR21-XPRO board.
At now, i've added the libraries and required features for it, it compiles
and i can use the "periph_adc" test, but i'm not able to find which GPIO
are used for the ADC.

In less words, i need an help to start using the ADC lines for a moisture
sensor.

I've found the watr-li tutorial (http://watr.li/Sensing-moisture.html), but
is deprecated.

There is someone who can drive me about it?


Thanks a lot,

Re: [riot-devel] [eeprom] [stm32l151] Driver for internal EEPROM

Yes, the NVRAM interface is the right choice for EEPROM.

I think usage of the ST standard peripheral library has been discussed
before, I have no time to search for the outcome right now. Please
search the mailing list archives and the issue tracker/pull requests.

Maybe you could link to the results you find from the FAQ in the RIOT
Wiki if you find it.

Cheers,
Ludwig
