Platformio-core: Problem with libraries

[ystrem]

Hello, I have problem with libraries. I can't get work the Serial work. The same I get when I try another library.

Code :

include

void setup(void)
{
// start serial port
Serial.begin(9600);

}

void loop(void)
{

}

pioenvs/arduino_pro5v/src/main.c: In function 'setup':
.pioenvs/arduino_pro5v/src/main.c:6:3: error: 'Serial' undeclared (first use in this function)
Serial.begin(9600);
^
.pioenvs/arduino_pro5v/src/main.c:6:3: note: each undeclared identifier is reported only once for each function it appears in
scons: *** [.pioenvs/arduino_pro5v/src/main.o] Error 1

[ystrem]

Or if I install OneWire lib and only include it to empty project I get this.

CODE :

include

include

void setup(void)
{
// start serial port
//Serial.begin(9600);
}

void loop(void)
{

}

Hello,

Which is extension of your file? main.c or main.ino?

• If you use main.c, you should include arduino header file:

#include <Arduino.h>

• You can change extension to main.ino, then PlatformIO will automatically include arduino header files.

[ystrem]

It help to change from main.c > main.cpp or main.ino. Now is working. Is possible to upload code by usbasp ? If I set proper env upload_port ?

[ivankravets]

It help to change from main.c > main.cpp or main.ino. Now is working.

Thanks for reporting :+1:

Is possible to upload code by usbasp ? If I set proper env upload_port ?

I hope, that you can upload it. Can you test it and report me? Thanks a lot!

[ystrem]

It's not possible.

[ivankravets]

Stop stop... Why not?

1. Did you specify usbasp protocol?
2. Can you share here your platformio.ini?

Try:

[env:some_env]
platform = atmelavr
framework = arduino
upload_protocol = usbasp

[ystrem]

I tried it and it looks good.

``` [env:pro8MHzatmega328]
platform = atmelavr
framework = arduino
upload_protocol = usbasp -B5
board = pro8MHzatmega328

avrdude: set SCK frequency to 187500 Hz
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e950f
avrdude: reading input file ".pioenvs/pro8MHzatmega328/firmware.hex"

avrdude: safemode: Fuses OK (H:05, E:DA, L:E2)

avrdude done. Thank you.
```

@ystrem thanks a lot for your platformio.ini and report. I've just added it to platformio.ini examples (number 5).

Have a nice weekend! :+1:
