RE: i.MX RT 1060 ADC

2020-09-16 Thread Thomas Axelsson 
Thank you, David,

It's good to have a working example.

Regarding the existing ADC code, I realized that I had only diffed over the 
various LPCxxx drivers. My current starting point is the LPC driver with things 
picked from the STM32. The LPC driver is simpler (STM32 handles many variants), 
while the STM32 driver has a clearer multi-ADC and multi-channel structure 
(although I just realized that mask in the LPC driver might be the channel 
selector). Just writing this here in case someone wants to point me in another 
direction.

Hi Thomas,

If you structure the driver like any of the other ADC drivers in tree you 
should be able to reference px4_arch_adc_init and px4_arch_adc_sample

from
https://github.com/PX4/Firmware/blob/master/platforms/nuttx/src/px4/nxp/im
xrt/adc/adc.cpp to get the required logic.

To fill in the meat, but you will have to do it in nuttx style using the
{get|set}reg32 calls.

Hi,

I'm looking into using the ADC on IMXRT 1060. I have found imxrt_adc.h and some 
examples in nuttx-apps using /dev/adcXX. However, it seems that the actual 
functionality is not yet implemented for IMXRT.

So I'm looking into implementing this driver, based on e.g. lpc17_40_adc.c 
(diffing all *_adc.c files turned up almost no differences). I tried grepping 
for some register names to see if the IP block is already implemented for 
another chip, but without luck.

I'm sending this e-mail to see if someone else is already working on the same 
thing. I did see that imxrt_adc.h has gotten some updates.

Wouldn't it be better to at least simply write "project moved to
nuttx.apache.org" and maybe some usefull links like wiki, mailing
list, git repo etc?  Right now someone might think project is dead
or something if one visits that site from an old resource.

Well, someone could host such simple site on his own webserwer. It would be
best if that was someone trustworthy so he doesn't replace links with
malicious ones somewhere in the future.

I could host it on my server if you wish.

No, no. I would never suggest to tranfer domain rights to me. You either
(1) specify DNS server for the domain (that will point to my dns server) or
(2) you manage your own DNS zone and only add "A" record and point it to
my server.

(2) is definately a way to go, since (1) allows me to setup subdomains
and even mail addresses with nuttx.org domain, while (2) will allow me
to control contents of single "http://nuttx.com"; domain - which of course
you can revoke by removing "A" record in your DNS zone.

Mind that (2) will also allow me to, for example do 'ssh nuttx.org',
which I will be able to redirect anywhere.

So yeah, you really need to ask yourself the question if you can afford
to give such power to some random dude on the net. I'm not saying I will
do any of it. But how can you know?

Fwd: Re: [nuttx] nuttx.org going away

2020-09-16 Thread Matias N. 
Not sure if this was received on the second list as well, so I'm forwarding to 
googlegroups. I'm lost on which discussion this conversation is taking place.

Let's just move to our new official URL. There's no point in having Greg keep 
the nuttx.org domain by himself and that someone else keeps a private server 
for this. It is only asking for more burden on individuals. The right approach 
is to use the community resources for this.

Best,
Matias

If you google "nuttx" the first result is Apache's site. If you explicitly 
google "nuttx.org", Apache's site is the second one.
We already switched references to nuttx.org in documentation so no point in 
keeping a second URL around even for a redirect. 

Best,
Matias
