lin = ucanlintools.LUC('COM7')
lin.set_frame_rx_handler(rx_any)
lin.set_new_frame_rx_handler(rx_new_data)

lin.openAsMaster()

lin.addReceptionFrameToTable(52,8)
lin.addReceptionFrameToTable(54,8)
lin.enable()

Example data reception handler

def rx_new_data(f):
        global message
        print (hex(f.id) + ": " +(f.data.hex()))
        if (message.id == f.id):
