Uploaded code doesn't work (stm32f103rc)

1

I have a custom designed pcb with stm32f103rct6 and i want to program it with platformio, first i tried blink example and uploaded the code with arduino ide and it works, but when i tried the same code in platformio it uploads successfully but the led doesn’t blink, it says target halted due to debug request i don’t know if that’s the problem.

platformio.ini:

[env:genericSTM32F103RC]
platform = ststm32
board = genericSTM32F103RC
framework = arduino
;debug_tool = stlink
upload_protocol = stlink

Any idea what could be the problem?

  • What code are you running exactly?
  • Did you use the Maple core or STM32Duino in the Arduino IDE?
  • Give a screenshot if the Arduino IDE → Tools menu so that we can see the exact configuration you used there?
  • What board are you running it on exactly? Does the board have a HSE crystal (e.g. 8MHz)?

Uploaded code:

int previousMillis = 0;        // will store the last time the LED was updated
int interval = 3000;            // interval at which to blink (in milliseconds)
int pin = PA15;

void setup() {
    // Set up the built-in LED pin as output:
    pinMode(pin, OUTPUT);
}

void loop() {
    // Check to see if it's time to blink the LED; that is, if the
    // difference between the current time and last time we blinked
    // the LED is bigger than the interval at which we want to blink
    // the LED.
    if (millis() - previousMillis > interval) {
        // Save the last time you blinked the LED
        previousMillis = millis();

        // If the LED is off, turn it on, and vice-versa:
        digitalWrite(pin,!digitalRead(pin));// Turn the LED from off to on, or on to off
    }
}

I used stm32 duino
It’s a custom design board, i have an external 16MHz crystal.

This configuration menu doesn’t look like the STM32Duino at all, and STM32Duino does not know of a “Generic STM32F103R series” board. Looks like you used Maple instead with this board.

As per documentation, add

board_build.core = maple

to the platformio.ini. Does it make a difference?

Thanks now it works, but a new problem appeared, i have a ili9341 display and i am using the adafruit library which works if i upload it using arduino ide maple, but it doesn’t work with stm32duino, and in vscode it doesn’t even work with maple, it doesn’t compile, but with stm32duino core it does compile but the display doesn’t work. Not sure why, any ideas?

errors when compiling in vscode with maple core:
