How to install and use

There aren't any installations. Clone the repository and use the methods. There are only two public methods:

• findall()
  This method returns all the ST-Link Probe number and corresponding COM port number.
• flash(hex_path, probe_no)
  This method takes the hex file path and the probe number (default = 0). It returns status ('successful' / 'failed') and the checksum of the hex/binary file.

Example

import stlink

if __name__ == '__main__':
    print(stlink.findall())
    status, checksum = stlink.flash('G:\\test.hex')
    print(status)

Output:

[{'probe': '0', 'com': 'COM4'}]
successful
