### Install stm32-mcp

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Clone the repository, set up a virtual environment, and install the package in editable mode.

```bash
git clone https://github.com/shieldyguy/stm32-mcp.git
cd stm32-mcp
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
```

### Start Live Memory Monitoring Session

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Initiate a live memory monitoring session for firmware variables using SWD. Specify variables by symbol name or address, the ELF file path, and the probe to use. The interval determines how frequently variables are polled.

```python
live_memory_start(
    variables='["blink", "ts"]',       # symbol names from ELF
    elf_path="/path/to/firmware.elf",
    probe="taillight",                  # board/probe nickname
    interval_ms=500                     # min 250ms
)
```

--------------------------------

### Activate Virtual Environment and Run MCP Server

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Activate the Python virtual environment and run the MCP server script. Ensure you are in the project's root directory.

```bash
source .venv/bin/activate
mcp dev src/stm32_mcp/server.py
```

--------------------------------

### Register stm32-mcp with Claude Code (Project Config)

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Configure the stm32-mcp server in your project's Claude settings file.

```json
{
  "mcpServers": {
    "stm32": {
      "command": "/path/to/stm32-mcp/.venv/bin/python",
      "args": ["-m", "stm32_mcp.server"]
    }
  }
}
```

--------------------------------

### Register stm32-mcp with Claude Code (CLI)

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Register the stm32-mcp server using the Claude CLI, specifying the Python interpreter path.

```bash
claude mcp add stm32 -- /path/to/stm32-mcp/.venv/bin/python -m stm32_mcp.server
```

--------------------------------

### Loopback Testing with pyserial

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Perform loopback testing for serial tools using pyserial's loopback functionality. This allows testing serial communication without physical hardware.

```python
import serial
ser = serial.serial_for_url("loop://", baudrate=115200, timeout=0.1)
ser.write(b"PING\n")
print(ser.read(100))  # b'PING\n'
```

--------------------------------

### Execute Hardware Sequences with Serial, Delay, Capture, and Memory Ops

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Define a sequence of hardware operations including serial communication, delays, webcam captures, and SWD memory read/write. This is useful for timing-sensitive hardware tests and bit-banging registers.

```json
[
  { "send": "SIM_LEFT", "to": "/dev/cu.usbmodem11202" },
  { "delay_ms": 500 },
  {
    "send": "GET_BLINK_STATE",
    "to": "/dev/cu.usbmodem11402",
    "expect": "BLINK"
  },
  { "capture": true, "label": "post_brake" },
  {
    "mem_write": true,
    "address": "0x48000418",
    "value": "0x40",
    "probe": "yellow"
  },
  { "delay_ms": 1000 },
  {
    "mem_read": true,
    "address": "0x48000400",
    "count": 2,
    "probe": "yellow",
    "label": "gpio_post"
  }
]
```

--------------------------------

### Read Recent Values from Live Memory Session

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Retrieve recent values from an active live memory monitoring session. Specify the session ID and the number of last entries to read. Full history is logged to a JSONL file.

```python
live_memory_read(session_id="abc123", last_n=10)
```

--------------------------------

### Stop Live Memory Monitoring Session

Source: https://github.com/shieldyguy/stm32-mcp/blob/main/README.md

Terminate a live memory monitoring session. This releases the SWD connection. The function returns session statistics including duration, read count, error count, and the output file path.

```python
live_memory_stop(session_id="abc123")
```
