What is wrong? Help please

PlatformIO IDE
1

I just start with PlatformIO and a NUcleo F446RE, but if I upload my program I get this, and what is wrong:

    • Executing task in folder Nucleo_f446re_CableRobot: C:\Users\asw.platformio\penv\Scripts\platformio.exe run --target upload

…but there is no error message visible at all? It flashed and reset successfully.

3

Yes okay, but it not running? so how do I set it in run?

4

The code you programmed should be running. What’s your code?

if I go to the debug console I see this:

Which is normal. It tells you it successfully hit the main() breakpoint in the Arduino framework. It shold then go on to call your setup() and loop() functions.

7

If I press on the buttons Run from the debugger the led on the Nucleo start flashing green/red

8

O sorry just start with PlatformIO, and before I always work with the Arduino IDE, without debugging… so this stuff is all new for me… And it is not easy for me all the english tutorials…

but if the led is flashing, it is running?

9

The LED on the ST-Link part just indicates debugger activity, that’s normal when you trigger any debugging options like halt, run, step-over, et cetera.

If the code still doesn’t seem like it’s running I need to see the platformio.ini and src/main.cpp content.

10

Can I zip the project directory and put it to download somewhere… because it is really a lot already…

it was a progam in a arduino, and now I try to get it running on a STM32

11

[env:nucleo_f446re]

platform = ststm32

board = nucleo_f446re

framework = arduino

monitor_speed = 115200

lib_extra_dirs = ~/Documents/Arduino/libraries

12

Do things step-by-step. Use a simple blinky to verify that you can generally upload executable code to the board, otherwise there’s no point in trying a more complicated sketch. The Nucleo does have an on-board LED.

Does this program blink the LED properly?

#include <Arduino.h>
#define LED LED_LD2

void setup() {
  pinMode(LED, OUTPUT);
}

void loop() {
  digitalWrite(LED, LOW);
  delay(1000);
  digitalWrite(LED, HIGH);
  delay(1000);
}
13

But I did that, and that was working… and I also have a TFTShield for the Arduino Uno/Mega… and I have run a demo for the tft screen on the Nucleo and it was a lot lot faster as on the Mega…

14

So thats why I start with this…

but the tft demo just start in run…? and now I get this?
So I don’t understand why the TFT demo starts in run… and this program not?

and I have also a Nucleo F446ZE, and also on that one, I did a blink test… with the different User leds… green and blue…

so that i thought it was time for the next step… :slight_smile:

15

Hard to say what’s going on without the code. Best to use “Start Debugging” and see if e.g. setup() completes correctly, loop() is executing or whether it’s crashing somewhere.

Yes, I don’t know if it is running or not? Don’t know where to look… :slight_smile:

I know the program was running in the Arduino IDE… Now I have it in PlatformIO… can build and upload…

only, in the program I use the serial monitor… and now the serial monitor does give any answer…

So or the controller is not running… or there is something wrong with the serial monitor? I Don’t know what is wrong, or what I do wrong…

I’ve never seen the UI elements pointed to by the green arrows – it seems you have different extensions installed besides PlatformIO, like the rivaling “Arduino” extension?
