### Installation Requirements

$ sudo apt-get install gcc build-essential cmake libusb-1.0 libusb-1.0-0-dev 

optional:

$ sudo apt-get install libgtk-3-dev pandoc 

---

### Installation
#### 1. Create shell script named "stlink_flash.sh"

#!/bin/bash

# Create a directory and navigate to it
mkdir STM32_tools
cd STM32_tools

# Clone the git repository
git clone https://github.com/stlink-org/stlink.git

# Navigate to the stlink directory
cd stlink

# Clean and build stlink
make clean
make release
sudo make install
sudo ldconfig

# Navigate back to the main directory
cd ../../

# Remove the created directory
rm -rf STM32_tools

#### 2. Add execution permission to script file

$ chmod +x stlink_setup.sh

#### 3. Execute script file

$ sudo ./stlink_setup.sh

#### 4. Validate Installation

$ st-flash

Successful Installation output:

invalid command line
command line:   ./st-flash [--debug] [--reset] [--connect-under-reset] [--hot-plug] [--opt] [--serial <serial>] [--format <format>] [--flash=<fsize>] [--freq=<kHz>] [--area=<area>] {read|write} [path] [addr] [size]
command line:   ./st-flash [--debug] [--connect-under-reset] [--hot-plug] [--freq=<kHz>] [--serial <serial>] erase [addr] [size]
command line:   ./st-flash [--debug] [--freq=<kHz>] [--serial <serial>] reset
......

Failed Installation output:

bash: /usr/local/bin/st-flash: No such file or directory

### Usage

$ mkdir ~/stm32_ws
$ cd ~/stm32_ws

#### 1. Create a file named "Makefile"

# in Makefile
flash:
	st-flash --reset write SAUVC2022.bin 0x08000000

reset:
	st-flash reset

#### 2. Copy binary(.bin) file to Rpi
- run in local (in root of STM32 workspace)
- change the IP below to Rpi IP (check with ifconfig)

$ scp build/SAUVC2022.bin pi@192.168.0.124:~/stm32_ws  

#### 3. Flash to STM32

$ make flash
