[Flashforth-devel] ff-shell3.py question

[Mark E. <mar...@gm...>]

Hi sorry..somewhat frustrated at the moment im sure there is something dumb i am doing / not doing but..

I *cannot* get the ff-shell3.py shell working at all .. M1 Mac, python 3.9.0

USB serial on /dev/tty.usbmodem13201

I changed tried running the ff-shell3.py with ‘python3 ff-shell3.py /dev/tty.usbmodem13201’ and get the dreaded “No such file or directory: /dev/tty.usbmodem13201’  even though I can connect to it with screen no issues.

So them I was looking at the code and see its got a serial port object “class Config(object)” and it so i changed default serial port to /dev/tty.usbmodem13201’ in it but still same issue.

hmm…. this should not be so difficult.

so i played with some simple python code inside the repl. just using see = serial.Serial(PORT, BAUD) using same port /dev/tty.usbmodem13201 and then ser.open() and I get “serial port is already open” .. so i do ser.close() first them ser.open() and it works, it sees my serial port just fine.

so why isn’t the ff-shell3.py seeing my serial port ??

TIA
Mark

So I added the close() and open() to serial_open(config) and it works 
just fine on linux, maybe then also on OSX.
Like this:

   try:
     config.ser = serial.Serial(config.port, config.rate, timeout=0.5, 
writeTimeout=1.0, rtscts=config.hw, xonxoff=config.sw)
     config.ser.close()
     config.ser.open()

Does that help ?

[Mark E. <mar...@gm...>]

thanks Mikael,

well… so after putting some debug prints in the code i found out the “No such file…” error message was due to the fact that its trying to find this file that did not exist and had nothing to do with the usb serial port !

  histfn = os.path.join(os.path.expanduser("~"), ".ff.history")

so once i ’touched’ ~/.ff.history  it ran until I hit this snag

local variable 'e' referenced before assignment

which… ‘e’ is used for the “try…except” ’s  and not sure why python is complaining about it since its always something like 

except Exception as e:  kind of thing

weird

So did you have to change some python statements to get it working on 
OSX ?

Something I could incorporate in the distribution ?

Re: [Flashforth-devel] ff-shell3.py question

[Mark E. <mar...@gm...>]

Hello Mikael,
OK…so chalk up this mostly to operator error..

the only thing I *really*  needed to do is create the “.ff.history” file before running the script.

the “missing file” error message I originally ran into was caused by that *but* I went down a rat-hole thinking there were other issues.

at one point though I did get the error message about  "local variable 'e' referenced before assignment”  BUT that is gone now and I cannot explain why except that maybe while playing with the code I did something bad..

but right now its working fine.

On to the tcl script though I cannot get that to work on my M1 MacBook air for some reason even though tcl/tk is installed.

i’ll start a different debug thread on that.

thanks
mark

Re: [Flashforth-devel] ff-shell3.py question

[Peter J. <p.j...@uq...>]

Mark, Mikael,
Until today, I have used the Tcl script only on Linux and Windows computers.  Your note prompted me to try it on a mac mini (M1) but I find that it becomes unresponsive once to tries to open the serial port.  Note that I start it from the command line as "wish ff-shell.tcl" so that I get the homebrew-installed Tcl/Tk 8.6 rather than the older 8.5 that seems to come with macOS.  I'll have to read the documentation to see what is different on a mac and to work out how to get the right environment when starting a script with a shebang.
Regards,
Peter J.
