TrinketKeybaord library (ATiny85) compiles in Arduino-IDE but not in PIO

skuenstler · December 11, 2018, 5:56pm

Hi,
I try to switch from Arduino IDE to Visual Studio Code using PlatformIO extension.
All my Arduino projects compile except one !

The one that does not compile is a small project with the Trinket from Adafruit (= ATiny85 under the hood).

The error I get has to do with the particular library I intend to use called “TrinketKeyboard”.
(The library shall not be confused with the TrinketKeyboar for Trinket-PRO devices !!).

Again, on the Arduino-IDE everything works fine. I installed the library on the Arduino IDE by importing a .zip-file.

The .zip-file import option obviously does not exist on the PlatformIO. There, I simply copy/paste the very same library into the lib-folder of my workspace. (like I did for all the other perfectly fine running PIO projects…).

However, the TrinketKeyboard Library does not work on PlatformIO and I am working on it since 4 hours. Now I give up unless somebody has a brillant idea

The error message says:

Can you post your full platformio.ini and lnk to the library? I’m only finding PlatformIO Registry which isn’t what you have according to you. What example code are you running?

Alright I guess you mean Adafruit-Trinket-USB/TrinketKeyboard at master · adafruit/Adafruit-Trinket-USB · GitHub.

I just compiled this without problems by doing:

download the full zip file of the repository
extract the TrinketKeyboard folder into the libs folder of the PIO project
open lib/TrinketKeyboard/usbdrv/usbdrvasm.asm and remove the last line end
copy the lib/TrinketKeyboard/TrinketKeyboardExample/TrinketKeyboardExample.ino to src/main.cpp (important).
build

Yes, you guessed the correct library !

One question to your suggested step #4 (i.e. copy the lib/TrinketKeybaord.... to screenshot/main.cpp (Important)

How did you exactly mean that ? (I don’t know how to copy a file to a file ? Did you mean to replace the one file or did you mean to add the file at the same location ? Can you please clarify ?

Then, to be complete on the library we are talking about:
I did two changes to the library (the one that you correctly found as well) - (as these were necessary also inside the Arduino IDE for successful compilation)

Here are the two changes from the original library :
(…however, I don’t think they are relevant for my original question tough, …but simply for completeness reasons I state them here below…) :

Make sure that line 17 and 18 show the following:

#undef __SFR_OFFSET
#define __SFR_OFFSET 0 /* used by avr-libc's register definitions */

Make sure that line 73 shows the follwowing:
#if 0x41 < 0x40 /* This is an I/O address, use in and out */

If the two changes are not made, the TrinketKeyboard library will not compile (not for Arduino IDE and not for PlatformIO under VSCode).

Just copy th example ino file to your src folder and rename it to the cpp extension. See file structure:

I did not have to make these changes for it being able to compile… What PlatformIO version are you using? (pio --version)

skuenstler · December 11, 2018, 7:32pm

Since I am completely new to PlatformIO - silly question where do I type: pio --version ???

Under PIO Home it says: Home 2.0.0 Core 3.6.2

The two changes I stated were indeed also necessary for the Arduino IDE. I am not sure if it has to do with the fact that I am on an older MAC book (late 2013) or if it has something to do with the USB driver.

I will now try what you explained… Thank you very much.

skuenstler · December 11, 2018, 7:37pm

I did move the example to the src folder and renamed it to main.cpp

But I get the very same error like the entire afternoon today:

My platform.io file looks as follows:

[env:trinket5]
platform = atmelavr
lib_extra_dirs = ~/Documents/Arduino/libraries/Arduino_applications/Learning/libraries
board = trinket5
framework = arduino

maxgerhardt · December 11, 2018, 7:40pm

Yes that’s your PIO version, and it’s the most recent one (good).

Strange because it doesn’t even tyr to compile the .S file… Can you rerun with verbosity on? Open a shell inside your IDE and type pio run -v.

skuenstler · December 11, 2018, 7:53pm

Here is the rerun with “verbosity” …

maxgerhardt · December 11, 2018, 7:56pm

Okay now we have the difference.

My PIO is trying to do

avr-gcc -x assembler-with-cpp -Os -Wall -ffunction-sections -fdata-sections -flto -mmcu=attiny85 -DPLATFORMIO=30602 -DARDUINO_AVR_TRINKET5 -DF_CPU=16000000L -DARDUINO_ARCH_AVR -DARDUINO=10805 -Ilib\TrinketKeyboard -IC:\Users\Maxi\.platformio\packages\framework-arduinoavr\cores\arduino -IC:\Users\Maxi\.platformio\packages\framework-arduinoavr\variants\trinket_tiny8 -c -o .pioenvs\trinket5\lib971\TrinketKeyboard\usbdrv\usbdrvasm.asm.o lib\TrinketKeyboard\usbdrv\usbdrvasm.asm

i.e., avr-gcc with the -x assembler-with-cpp flag.

But yours is trying to use avr-as with the exact same set of GCC flags, which won’t work. I have no idea why.

Can you please just delete the usbdrvasm.asm file? It should still try to compile the .S file normally.

Since I am on Windows, this might be an macOS specific problem…

skuenstler · December 11, 2018, 8:00pm

NOW IT WORKS

Oh dear - how on earth would I have guessed ! Thank you very very much !

Do you know why one can delete the usbdrvasm.asm without any consequences ??

maxgerhardt · December 11, 2018, 8:02pm

Great. Still a macOS bug in PIO I think. @ivankravets?

Well the header file states that this file just exists because it compiles for the IAR toolchain. Since we’re using GCC and all the file is doing is a

#include "usbdrvasm.S"
//end

I see no reason to not delete it.

skuenstler · December 11, 2018, 8:09pm

Hm - educated guess…
Again, thank you very much !

ivankravets · December 12, 2018, 12:55am

Indeed, this is a bug and I’ve just fixed it in Ignore *.asm and *.ASM files when building Arduino-based library (com… · platformio/platformio-core@b874359 · GitHub

Arduino builder ignores *.asm and *.ASM files. We did the same for Arduino-based libraries.

Please set platformio-ide.useDevelopmentPIOCore to true in Redirecting.... Restart VSCode. Open PlatformIO IDE Terminal and type pio upgrade --dev.

Does it ignore ASM files now?

skuenstler · December 13, 2018, 6:29pm

@ivankravets: Thank you for your effort. However we are not there yet

After setting to true as you requested inside PIO’s settings…

…and restarting VSCode, I typed as you suggested, inside a Terminal… pio upgrade --dev
It states:

PlatformIO has been successfully upgraded to 3.6.4b1

Then I closed and re-opened VSCode.

However, I still get the very same error as before!!

I can only eliminate the error with the workaround that @maxgerhardt suggested (i.e. deleting the file usbdrvasm.asm inside the library-subfolder)…

Could you provide a simple project (archive) to reproduce this issue? You can share it on Dropbox or other services.

nyaray · June 11, 2019, 8:28pm

Hi, I’m getting the same problem with the latest version of VS Code and the PIO extension, but the recommended fix works, so there’s that :).

Cheers!

majuss · March 7, 2020, 10:28am

The bug is still present… however renaming the asm file to a hidden one works fine.
