pySympleAF

This represents a basic Python wrapper for interfacing with the SympleAstroFocus Project.

It's presently in early stages but includes defined data types and bit fields, as well as converters for driver current settings and status.

Example Usage

Refer to demo.py for details on usage, but the rough summary is:

with hid.Device(SAF_VID, SAF_PID) as h:
    saf = SympleAutoFocus(h.serial)

    print(f'Product: {h.product}')
    print(f'Serial Number: {h.serial}')

    read_command = (SAF_GUID_1 & 0x7FFFFFFF)
    read_command_int = read_command.to_bytes(SAF_PACKET_BYTES, SAF_ENDIAN)

    h.write(read_command_int)

    while True:

        this_read = h.read(READ_SIZE, timeout=READ_TIMEOUT)

        for this_packet in grouped(this_read, 8):
            saf.handle_packet(this_packet)

        try:
            print(saf.driver_status, saf.target_position, saf.max_position, saf.command_status, saf.driver_type)
        except SympleAFUninitialisedValue:
            pass
