96boards / 96boardsgpio Goto Github PK

Please, correct this variable at the file.
It's causing an error when I perform a sudo make install at my DragonBoard 410c.
After I changed it, it's been working fine.

libsoc doesn't have a file called: autogen.sh

You need to run: autoreconf -i

So I think you should fix the docs

I try to build it on the dragonboard 410c, but I get a build error:

error: 'LS_SHARED' undeclared; did you mean 'LS_GPIO_SHARED'?

same problem as here
#15

@jguilfoy solution works but its not pushed to repository
current code is still

gpio *g = libsoc_gpio_request(gpio_id, LS_SHARED);
if (!g)
return rc;
if (!strcmp(direction, "in"))
rc = libsoc_gpio_set_direction(g, INPUT);
else
rc = libsoc_gpio_set_direction(g, OUTPUT);

Slightly pedantic maybe ...

The spec uses (-) and the python bindings use underscores (_)

So should:
GPIO_A = GPIO.gpio_id('GPIO_A')

be:
GPIO_A = GPIO.gpio_id('GPIO-A')

This file is used by this package but never be created. Is it possible to generate this file during package installation? Or, it's better to specify it in the document and let the user create it manually.

I won't like all the issues, but:

• 'cp' instead of 'install'
• no DESTDIR support
• /usr/local hardcoded
• not located in the top-level

You have an ambiguous mix of GPL (COPYING) and LGPL (LICENSE, and other file headers) in the archive. Which is it?

Hello,

I appear to be having issues using the Python bindings on the Dragonboard 410c. I'm getting the following message when importing the library in to Python:

OSError: lib96BoardsGPIO.so: cannot open shared object file: No such file or directory

The file does exist in /usr/local/lib

Is it possible that you could create a Python Package and put it on PyPi?

Thanks,
Barry

Hello, I don't know if this is really the place to ask this but I have searched elsewhere and didn't find anything, sorry if this is not to be posted here.

I am trying to build the example blink.c, have installed 96boards and its dependencies (via the autoreconf -i option), but it won't compile the script.

I am using this command : g++ blink.c -o Blink -lsoc -l96BoardsGPIO

I am getting these errors :
main.c:(.text+0x8c4): undefined reference togpio_id(char const_)'
main.c:(.text+0x8dc): undefined reference to gpio_open(unsigned int, char const_)' main.c:(.text+0x904): undefined reference to digitalWrite(unsigned int, unsigned int)'
main.c:(.text+0x91c): undefined reference todigitalWrite(unsigned int, unsigned int)' collect2: error: ld returned 1 exit status

Would you have any idea how to correct this error please ? Sorry if this is a newbie question

Cheers, Pierre

Have you looked at https://github.com/jackmitch/libsoc ?

gpio.c converts dashes to underscores in GPIO names and translates pin numbers and letters to names with underscore. However it appears that libsoc configuration uses the dash convention by default: https://github.com/jackmitch/libsoc/blob/master/contrib/board_files/dragonboard410c.conf

Which one is more right? :)

If one tries to get a GPIO using gpio_by_pin(23) libsoc is eventually asked for GPIO_A which is not in the above configuration.

Couldn't find the packaged libsoc for e.g. the Linaro Debian release for the DragonBoard right now to check, so it could be fixed there.

One idea is to include both dashed and underscored mappings in libsoc configuration as aliases.

Thanks!
