Is SPI ported?

[crystalthoughts]

Hello, is SPI part of the GPIO library ( I see a function mode referring to it) or is this not yet ported?
Thanks for the library!

[Martinix75]

No! It hadn't been implemented, but in fact it would not be a bad thing to do it! It could be very useful.

[crystalthoughts]

Yess I think that's a key piece needed to get most projects with a screen going :)
Have you tried using Futhark to speed up the porting process?
I'm not really experienced enough in embedded to do a good job contributing to this unfortunately, otherwise I would try!

[crystalthoughts]

#62

It looks like this pull request has it covered (seemed also to use Futhark)

[Martinix75]

Yes, I tried Daniel's project, but I always fail in compilation !!! I don't know why but I'm not a programmer too and goes beyond my skills.
For now (and for work) I use the I2C screens. And for now they are more than enough (sh1106 and ssd1306)

[crystalthoughts]

@daniel-j there are some downstream dependencies that aren't handled by the nimble file (pico-vfs -> littlefs)
edit: And the tests fail at test-mock.nim for me

[crystalthoughts]

I also get this when I try the examples

[daniel-j]

@Martinix75 Hello! Can you describe or show the error that occur?

@crystalthoughts Hmm, not sure what may be the issue. What are the error messages from the compilation or configuration? The screenshot only shows cmake failed but it doesn't show what cmake error it was. LittleFS is now loaded from within pico-vfs. Make sure to clone picostdlib recursively!

Hi Daneil, sorry for the delay for the answer, but I was not at work!
I am attaching you below the error that brings me back (everything).
But I would say that the certain is "Fatal: 'sys/time.h' file not found ".
I use OpenSUSE SLOWROLL/TW
GCC-13 (GCC-13 Cross Arm None)
Clang 19.x
Nim 2.2.0
Maybe only a few files/package is missing? I would not know.

Thanks for the help from Martin A.
p.s. If you need more information, he tried to provide you as soon as possible (even if at Christmas it will be difficult)

I have the doubt that I stay making a stupid error from something else!
SDK type is downloaded automatically or do you have to indicate where it is ??? What if yes? (I have this terrible doubt)

For completeness of information I give the command:
nimble install https://github.com/daniel-j/picostdlib.git

in /home/andrea
am I doing correctly?

[daniel-j]

Hi Make sure package cross-arm-none-newlib-devel is installed as that contains sys/time.h for embedded. Daniel

Yes! The "cross-arm-none-newlib-devel (version 4.4.0.xxx)" pachet is installed.
And the file is in "/usr/arm-none-eobi/includa/sys/time.h"

I can't understand that file does not find it here:
Fatal: 'sys/time.h' file not found /tmp/nimble_6188/githubcom_danieljpicostdlibgit/build/futharkgen/_deps/pico_sdk-src/src/rp2_common/pico_lwip/include/arch/cc.h:35:10 1638

What is wrong in the installation of your nimble package?
I am really afraid to make some stupid installment error of your package!

[daniel-j]

Sorry for the delay. What does arm-none-eabi-gcc -print-sysroot print? I pushed an update now to use /usr/arm-none-eabi/include as fallback if it exists.

[Martinix75]

Hi @daniel, sorry for the delay of the answer (and the test) but the Christmas holidays are a nightmare.
This morning I copied your library and after the Commit it works, or at least it is completed without errors! Thank you.
In these days I will try to make a plan and see if everything works. But for now thanks !!!

I disturbed you (maybe) if I find other problems!

[Martinix75]

Hi @daniel-j
In these days I am a little playing with "spi.nim"
I noticed two things:
1 - The names are not consistent, while for i2c the names of the functions begin for i2c (eg i2csetu, i2cwritebloking ...) while for spi no (would be perhaps better if you start for spi?)
2- The function (SPI) write16Blocking does not work well (and on oscilloscope) by very strange results that are not read well from the SPI device that I have (MCP42050). I have allowed myself to write a nim procedure that seems to work well (for the writing of 16 continuous bit) but needs a particular setup (procedure) that I have written anyway.
When I try it well if you want I send it to you.

Hello from martinix
