Arduino for STM32

I modified the code from Adafruit.But always i got no address found.But the two libraries are same.

#include <OneWireSTM.h>
OneWire net(PA12);
uint8_t address[8] = { 0, 0, 0, 0, 0, 0, 0, 0 };
void setup(void) {
Serial.begin(9600);
}

void loop(void) {
byte i;
byte present = 0;
byte addr[8 ...

Hy,
Sorry I can't understand what you told. can you explain little more detail. I saw onewireSTM library in github.is this library working for that IC.

Hy,
I'm using Ds2413 one wire ic to control the many gpios.It was worked well with Arduino.But I wish to implement project with STM32,is there any library for stm32?
