git clone https://huggingface.co/MuratKomurcu/stm32-hal-codegen
```

### 5.2 Quick Start

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

# Load model and tokenizer
model_name = "MuratKomurcu/stm32-hal-codegen"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Generate STM32 code
prompt = """// STM32_PROJECT: LED_CONTROL
// FAMILY: STM32F4
// TASK: Generate STM32F4 HAL LED blink code
// REQUIREMENT: Blink LED on PC13 every 1000ms

"""

inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(
    inputs["input_ids"], 
    max_length=800, 
    temperature=0.8,
    do_sample=True,
    top_p=0.9,
