STM32 PlatformIO

@TrystanLea

I’ve now amended my test code to print out, Vrms, Irms, realPower, apparentPower and powerFactor as floats with the makefile modifications you mentioned.

BINPATH = /usr/bin
CFLAGS += -std=gnu99
LDFLAGS += -Xlinker --no-wchar-size-warning -u _printf_float

The printf_float linker flag has also been added to platformio.ini and now works great to compile and upload dBC_txshield_demo using platformio. To get up and running from scratch on any machine (full tool-chain install), first install platformio then run:

$ git clone https://github.com/TrystanLea/STM32Dev/
$ cd dBC_txshield_demo
$ pio run -t upload
$ pio device monitor

Here is an extract from platformio.ini showing the build flags:

https://github.com/TrystanLea/STM32Dev/blob/master/dBC_txshield_demo/platformio.ini

Without anything connected I get;

$ pio device monitor

@glyn.hudson - you still need to gnu99 flag as well and even with your new settings there is still an issue on Pi. All the console output in this post is one session, I have chopped it up only for the purpose of adding notes and hopefully making it more digestible.

I last had this running last night (confirmed compile and flash using PIO) and I have not changed anything in the interim. First off, I did not expect it to need to re download the toolchain, what should have been a simple recompile of last nights code took ages.

8 minutes is a long time, anyway, it failed to compile and I wasn’t sure why so I just ran it again (just “run” without “upload”) and this time it has given me a better description of the error and what to do about it.

It seems to have a problem deleting some temp files and it asks me to do it manually, which I do and then run “run” again.

This time it gets a bit further but I see the same error we were getting a couple of days ago telling us to use the gnu99 flag that dBC has included in the Makefile extension .mak file. So at this point I add build_flags = -std=gnu99 to the end of your platformio.ini and try again.

It failed with the same error again, I tried it again, this time with run and upload (shouldn’t be different I know, but you never know)

a couple of warnings but it compiled ok, as the “upload” command was used this time it had installed to my stm32 but when I checked the serial output it is without data

This isn’t a emonSD, it’s a Pi3 with the March 18 Raspbian Stretch and only the minicom and Arm toolchain packages installed plus PIO via the “quick install” method.

I might try v5 later tonight but I expect the same results, if you have any idea’s or further flags I should try, let me know, but it is unlikely I will re install PIO when I re-flash this sdcard to test installing the minimal arm toolchain plus minicom installation method from a fresh image.

[glyn.hudson]

Mmm strange, I’m unable to replicate. The code compiles fine for me without the std=gnu99 flag.

I was dev version of PlatformIO currently version 3.5.3a7, to test I reverted to the non dev version of platformio version 3.5.2 and still unable to replicate.

However I’ve added the build flag to platformio .ini (currently in PR to trystans repo). I didn’t seem to make any difference for me.

add std=gnu99 pio build flag

Build flag variables need to have -D in front of them e.g.

glynhudson/STM32Dev/blob/master/dBC_txshield_demo/platformio.ini#L14

http://docs.platformio.org/en/latest/projectconf/section_env_build.html#id1

Please confirm if this fixes the issue for you. What version platformIO are your running $ pio --version?

For comparison here is my compilation output:

I’m unable to replicate. The code compiles fine for me without the std=gnu99 flag.

I expected that would be the case which is why I included all the info.

pi@raspberrypi:~/redo/txshield_demo_3/emonTxshield $ pio --version
PlatformIO, version 3.5.2

@glyn.hudson

Build flag variables need to have -D in front of them e.g.

Ok, seems to work without it but I will try it with the -D tomorrow sometime.

@glyn.hudson

Please confirm if this fixes the issue for you.

indeed I shall

For your information workIng OK on Windows 10.

I installed PlatformIO originally to be able to upload firmware to emonESP.

So starting with a fresh copy of dBC’s v5 tar (coned from GitHub - stm32oem/stm32tests) I just added your full platformio.ini content from your github link (STM32Dev/platformio.ini at master · glynhudson/STM32Dev · GitHub) as a new file in the root of the project folder and it failed to compile with the same “gnu99” errors.

looking at the content of that ini file, it getting kinda busy in there an I’m not sure what is really necessary and whats not.

I can see you are putting the build flags in a variable in the [common] section and then using ${common.build_flags} in both the dev and non-dev environments. I decided to try what worked for me previously and just stuffed “build_flags = -std=gnu99” in there, since there was now 2 env sections I put it at the end of the [common] section like so

[platformio]
src_dir = Src
include_dir = Inc
env_default = stm32f303-dev

[common]
# Specify flags/variables commmon to all enviroments
# PlatfomIO common variables docs: http://docs.platformio.org/en/latest/project$
# PlatfomIO build_flags docs: http://docs.platformio.org/en/latest/projectconf/$
monitor_baud = 115200
debug_flags = -D DEBUG=1
build_flags =
  -Wl,-u_printf_float
  -D std=gnu99

build_flags = -std=gnu99

# Dev build enviroment (default)
# $ pio run -t upload
[env:stm32f303-dev]
platform = ststm32
framework = stm32cube
board = nucleo_f303re
monitor_baud = ${common.monitor_baud}
src_build_flags =
  ${common.build_flags}
  ${common.debug_flags}

# Non dev build enviroment, specify enviroment using:
# $ pio run -t upload -e stm32f303
[env:stm32f303]
platform = ststm32
framework = stm32cube
board = nucleo_f303re
monitor_baud = ${common.monitor_baud}
src_build_flags = ${common.build_flags}

That compiles and loads just fine

I just tested compiling stm32tests/emonTxshield at master · stm32oem/stm32tests · GitHub using platformIO (copied over the same platformio.ini) and it worked for me. I’ve created a PR to add the platformio.ini

add platformio.ini

What version platformio are you using `$ pio --version"?

@glyn.hudson

What version platformio are you using `$ pio --version"?

I’m still running…

@pb66

pi@raspberrypi:~/redo/txshield_demo_3/emonTxshield $ pio --version
PlatformIO, version 3.5.2

only installed a few days ago specifically to try this out so it cannot be that far from the latest

@glyn.hudson

and it worked for me.

That’s great, but what platform are you testing this on? Is it a PI?

@glyn.hudson

I’ve created a PR to add the platformio.ini

Great! I was going to do it once I got it working, I have started a new branch “platformio” so that we can get this fixed and I’ll add some doc notes too.

The version you have submitted will simply not work for me, whilst I’m not overly concerned about that, I assume it is more to do with using a PI rather than specifically a problem unique to me personally, so if it’s in the repo IMO it needs to work for me too even if I’m not using it as I might end up supporting it.

Pi’s are not exactly uncommon around here

If I get time over the weekend, I will try again from scratch IF you are saying you have confirmed this as working on a RPi yourself.

[Paul (Paul Reed)]

Just installed Platformio on my Debian VM, cloned stm32oem (platformio branch) followed by sudo pio run -t upload and it successfully (and very smoothly!) compiled and uploaded the code to the STM32.

Running the pio monitor gave the error;
could not open port '/dev/ttyACM0': [Errno 13] could not open port /dev/ttyACM0:
…but running the command again as root - sudo pio device monitor ensured that Miniterm could access the port, and then all was well.

During the Platformio install process, I did get some warnings, but I assume that they can be disregarded.

That’s odd I don’t get that error. Does your user belong to the dialout groups? The pi user is in the dialout group by default in the Raspbian images

pi@raspberrypi:~ $ groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi

@Paul

During the Platformio install process, I did get some warnings, but I assume that they can be disregarded.

Install or compile?

I get some warnings during compile too, I get some with the “make” routine and standard ARM toolchain too, but Ive never really studied the content, I did read it a couple of times when we started this but the info didn’t stick.

[Paul (Paul Reed)]

@pb66

That’s odd I don’t get that error.

It could be because the usb device is mounted within a VM which isn’t quite the same as a physical machine.

@pb66

Install or compile?

Install. I don’t get any errors during compile.

Edit - in fact I do, the same errors occur during compile too, except the warnings are only visible if it’s run in verbose mode. - sudo pio run -t upload -v

Must admit, I was a sceptic about using Platformio, but having tried it I’m impressed.

[pb66 (Paul)]

@Paul

Must admit, I was a sceptic about using Platformio, but having tried it I’m impressed.

I’m not sold on it, most of the negativity comes from having it thrust upon me at very regular intervals and having to explain why I’m not using it.

It is overkill for use on the Pi (and it currently doesn’t work which doesn’t help) the deb package and minicom works well and it’s maintained via apt-get, I have no need for more clutter. As I ve said before the serial monitor is nicer than minicom, but I wouldn’t install it just for a serial console.

Beware of using sudo with PIO. If you inadvertently use it for the compile command, it will write the temp files as root and not be able to delete them next time you compile as non-root. I have no doubt sudo make will probably do the same, but as I’m not using any sudo commands whilst compiling/flashing and viewing the serial output it’s a mistake less likely to happen for me.

Do you have to use sudo with minicom too?

[pb66 (Paul)]

Well I never…

I just found Miniterm is installed as part of the standard Raspbian image. So there is no reason for me to install Minicom (which I dislike). I can just install the ARM toolchain alone and use Miniterm.

how great is that?

I can just set up an alias to include the settings and path like I have for Minicom and issue a single word command to open the Miniterm serial console at the right baud and path, Fantastic!

[Paul (Paul Reed)]

@pb66

Do you have to use sudo with minicom too?

Yes.

@pb66

Beware of using sudo with PIO.

Well the compile command is run by root sudo pio run -t upload - see Trystan’s readme.md

Ohh! That’s not good! So make won’t work after using PIO either? Unless you use sudo too. That cannot be right, it installs it’s toolchain in the users home folder, not in the root filesystem, it shouldn’t then expect you to use sudo. Did you install with sudo or not?

[edit] Do you have a .platformio folder in your users home directory? Is there one at the root users home directory too?

[edit2] If you have more than one .platformio folder, can you tell which is being used? latest file times or rename one of them to see it is causes an issue.

[edit3] If you look at Glyns first post in this thread he doesn’t use sudo either (and his middle name is platformio), but I suppose he may be a root level user.

[edit4] In the PlatformIO: Compile & upload firmware. Blog post 1/3 thread, there is a variety of sudo and non-sudo commands but no explanation as to which or why. I think some clarification may be in order here.

[Paul (Paul Reed)]

@pb66

Did you install with sudo or not?

Yes, I used the Platformio installation script (and yes sudo was required)

@pb66

Do you have a .platformio folder in your users home directory?

Yes, but it only contains a Platformio json config file - no other data

@pb66

Is there one at the root users home directory too?

Yes, but that folder contains Platformio’s libraries, toolchains, etc.

@pb66

If you look at Glyns first post in this thread he doesn’t use sudo either (and his middle name is platformio), but I suppose he may be a root level user.

Maybe. That’s one for Glyn to answer!

EDIT - there is a way to install Platformio local to a user, but pip is needed (the package management system for Python). I didn’t really want to install pip, as it’s yet more baggage I probably wouldn’t use again!!

[pb66 (Paul)]

I have both since I ran the compile with sudo by accident the other day and that’s how I came to learn about the issue with root owned temp files as I only made the error once and then couldn’t use non-sudo as I was used to.

I too installed with sudo for the installer, I only asked to see if there was a difference.

If you delete the temp files in .pioenvs will it then compile without sudo?

sudo rm -r /home/pi/redo/txshield_demo_3/emonTxshield/.pioenvs

(edit to suit your user and path)

although it looks like all your files are root, you may need to chown the project folder instead.

[pb66 (Paul)]

@Paul

EDIT - there is a way to install Platformio local to a user, but pip is needed (the package management system for Python). I didn’t really want to install pip, as it’s yet more baggage I probably wouldn’t use again!!

PIP is also included as standard on the Raspbian image, but PIO installed it again, or so it told me, I don’t actually know if the message was accurate, but I recall I was annoyed whilst watching it apparently install PIP when I knew it was already there.

I use a lot of Python so PIP is generally something I use.

I think you have a non-sudo PIO, but once you use sudo you are stuck unless you remove or chown the files.

You souldn’t need sudo to flash the stm32 as it’s mounted to the users media folder so you shouldn’t need sudo at all for the run or upload commands.

For acces to the serial port to negate using sudo with miniterm try adding your user to the dialout group with

sudo usermod -a -G dialout $USER

you might need to log out and in, or start anew shell to get the new group permissions. Check it with groups .

[Paul (Paul Reed)]

@pb66

although it looks like all your files are root, you may need to chown the project folder instead.

My main project files are not root.
But, after deleting .pioenvs and running platformio without sudo, it again downloaded the toolchain, libraries and support files to my user root (so like you - I now have a set in root users home directory & a set in user home directory!!) it then went onto successfully flash the STM32.

However, the .pioenvs is now user owned;

I suppose the test now is to delete the library files (except the json config) from the root users home directory, but being a gentleman - you first!!

I just renamed the copy in the root folder so PIO couldn’t find them
