Perfect, I will add a link to your documentation on the PX-41CX website.

Being Python the tool should work on Windows and Linux as well. It's just that I didn't try it. I updated the Documentation to make that more clear. Now I just need someone to actually try it out.

Just replace line 60 in Receive.py

Quote:print (Line.decode ("Latin1"), end='')

by

Quote:print (Line_Array.decode ("Latin1"), end='')

and everything works under Windows!

My Windows command files :

(1) px41cx_Receive_Dump.bat

Quote:@echo off
:start
cls
@echo +====================================+
@echo ! RECEIVE PX41CX DUMP !
@echo +====================================+
SET USB_Serial_Device=COM8:
SET USB_Serial_Speed=115200
SET dump=Dump.px41
SET /P dump="DUMP file ? (name.ext)"
if "%dump%"==" " GOTO enddmp
cd..
python tools/px41cx_Receive.py %dump%
pause
:enddmp

(2) px41cx_Send_Dump.bat

Quote:@echo off
:start
cls
@echo +====================================+
@echo ! SEND PX41CX DUMP !
@echo +====================================+
SET USB_Serial_Device=COM8:
SET USB_Serial_Speed=115200
SET dump=Dump.px41
SET /P dump="DUMP file ? (name.ext)"
if "%dump%"==" " GOTO enddmp
cd..
python tools/px41cx_Send.py %dump%
pause
:enddmp

to adapt according to your own context.

As promised I have written a proper installation guide for macOS and Linux.

Linux, of course, is untested.

Hello,

I updated the firmware flash script to also patch the firmware first. Now you can download the newest version, apply a patch and flash a new firmware in one go. On macOS and Linux that is.

Hello,

Pierre (mostly) and me (a little) created a python script which will download screenshots without the need of copy paste. It can store multiple screen shots so there is no need to restart the program. Usage is fairly simple:

Code:


export USB_Serial_Device=/dev/tty.usbserial-14440
export USB_Serial_Speed=115200

Screenshots.py Image 

For screen shots use «MENU» ⇒ «SHIFT» on the PX-41CX
Press `Ctrl-C` to end the program.

Hi,
Thanks Alex for a great kit. I bought myself the PX-15C a few months ago, and my daughter bought the PX-41CX for my recent birthday. I enjoyed the build process on both very much.
I've managed to get my head around the python tools to a) upload new firmware and b) to modify the firmware with personalised settings - I've updated the "info" text and am using 0902 firmware.
I have also worked out how to dump and load from and to the PX-41CX via the serial port (I'm using Windows 11 and CoolTerm as recommended).

<EDIT> I believe my problems were PEBKAC - my own fault. I suspect I was habitually pressing the lower-right button expecting to hit R/S, but of course the ON button is there now. <insert facepalm>
I have a program on the PX-41CX that behaves incorrectly. At a certain point in the program, the calculator turns itself off, but turning it back on and pressing R/S gets it going again and the program resumes. Depending on the answers to the early questions my programs ask, this behaviour can happen once or twice, but there after, the program runs fine. The program I wrote was to track the progress of T20 or 50-Over cricket matches. If you want to upload and run it (the program name is "RPO" for Runs Per Over), the calculator dump is:-
