Hi, I'm a french student and I'm trying to use a STM32L475 VG Discovery kit with Arduino IDE for a project. I downloaded the last version of the softwar and then, I installed the libraries for STM32. The first program I tried to run was this one:
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
The problem is that during the compilation ther is an error message:
c:\users\mathi\appdata\local\arduino15\packages\stm32\tools\arm-none-eabi-gcc\6-2017-q2-update\bin../lib/gcc/arm-none-eabi/6.3.1/../../../../arm-none-eabi/bin/ar.exe: unable to rename 'core\core.a'; reason: File exists
exit status 1
Erreur de compilation pour la carte Discovery
Can you help me and tell me what to do please? Thannks
