Question on sending commands via Serial

[JLee21]

Hi!

I was wondering if you had any code that exemplified sending the Flir commands via serial?

Is it something as simple as this:

functions = FLIR_Functions()

noop_cmd = functions.noop()

ser = serial.Serial('my_port', 9600)
ser.write(noop_cmd)

Hi,

Yes, it is as simple.

This is how I write to serial using the commands lib, a bit long explanation but I hope it helps:

from libflir import *

libFLIR = FLIR_Functions()
_serial_FLIR = Serial_Functions_FLIR()
_serial_FLIR.serial_init_FLIR()

This is the Serial_Functions_FLIR class:

class Serial_Functions_FLIR():

        def __init__(self):
                self.parse = Parser_Functions()
                self.parse.parser_init()
                self.parse.ConfigSectionMap()

        def serial_init_FLIR(self):
                _section = 'FLIR'
                _device = self.parse.getSectionOption(_section, 'device')
                _baudrate = int(self.parse.getSectionOption(_section, 'baudrate'))
                _parity = self.parse.getSectionOption(_section, 'parity')
                _stopbits = int(self.parse.getSectionOption(_section, 'stopbits'))
                _bytesize = int(self.parse.getSectionOption(_section, 'bytesize'))
                _timeout = int(self.parse.getSectionOption(_section, 'timeout'))
                _inter_byte_delay = float(self.parse.getSectionOption(_section, 'inter_byte_delay'))
                self.ser = serial.Serial (port = _device, baudrate = _baudrate, timeout = _timeout, \
                           interCharTimeout = _inter_byte_delay, parity = _parity, stopbits = _stopbits, bytesize = _bytesize)
                self.ser.flush()

        def receive(self, _bufsize):
                _buf = self.ser.read(_bufsize).encode('hex')
                self.flush_buffer()
                return _buf

        def serial_write(self, _cmd):
                self.ser.write(_cmd)
                print "wrote: " + _cmd

        def serial_read(self, _bytes):
                return self.ser.read(_bytes).encode('hex')

        def get_serial_conf(self):
                print self.ser.getSettingsDict()

        def flush_buffer(self):
                self.ser.flush()

This is what the conf file looks like, note the INTER_BYTE_DELAY required for TAU 3xx:

[FLIR]
DEVICE=/dev/ttyUSB0
BAUDRATE=57600
PARITY=N
STOPBITS=1
BYTESIZE=8
TIMEOUT=0
INTER_BYTE_DELAY=0.1

This is how the command is written to serial, as an example:

_serial_FLIR.serial_write(libFLIR.camera_reset())

We use a piece of code that is like an RPC server listening on UDP, bunch of async threads that get data in/out of the RPC<->Queues and write to serial, let me know if you need any further assistance and I will be happy to assist you there.

Thanks.

Hi, That is some good work, if possible could you please share the code updates and maybe few tests with us? Thanks, Weqaar A. Janjua

Understandable, only if possible I would like to merge your changes/additions in libflir, I can put in the effort for this. Please let me know if there is any possibility otherwise no worries at all. Thanks, Weqaar A. Janjua

I'll have to ask my boss about it I'm reviewing the code and it feels large and kinda messy. At first glance, I don't think it'll merge nicely with yours even though the core of it is fairly similar. PS I've been looking at @Aelphy <https://github.com/Aelphy> and his python code. Its footprint is quite small and so I'd like to look into that as well. — You are receiving this because you were mentioned.
