Arduino for STM32

Posted: **Tue Mar 22, 2022 7:29 am**

Hi,
I'm changing my project core to newer one of stm32duino. I'm getting many many errors, which is expected. But the problem comes when a library becomes incompatible at fullest. One of which is https://github.com/mike-matera/ArduinoSTL. It was working fine on Steve's core but not on new core v.2.0.0.

Also I have a static method of a library with USBSerial* and now getting the following error

error: 'USBSerial' does not name a type; did you mean 'Serial'?
18 | static USBSerial *DebugSerialUsb
| ^~~~~~~~~
| Serial

in CoreLib class

static USBSerial *DebugSerialUsb;
static HardwareSerial *DebugSerialHardware;
static void Init(HardwareSerial *DebugSerial);
static void Init(USBSerial *DebugSerial);

in main .ino

USBSerial *CoreLib::DebugSerialUsb = NULL;
HardwareSerial *CoreLib::DebugSerialHardware = NULL;

then later init them whenever need to.

I'm not getting error on HardwareSerial only on USBSerial.

You have to enable USB in the menu. The name is SerialUSB.
About STL, it is not required as the core already use the C++ standard library by default.

Simply like that:

Code: Select all

#include <vector>
using namespace std;

template<typename T> void printVect(T const & xs) {
  Serial.print("[ ");
  for (auto const & x : xs) {
    Serial.print(x);
    Serial.print(" ");
  }
  Serial.println("]");
}

void setup() {
  vector <int> numbers;

  Serial.begin(115200);

  printVect(numbers);
  numbers.push_back(5);
  numbers.push_back(3);
  numbers.push_back(4);
  printVect(numbers);
  numbers.pop_back();
  printVect(numbers);
}

void loop() {
}

Result:

Code: Select all

[ ]
[ 5 3 4 ]
[ 5 3 ]
