RE: PX41CX Firmware installation on macOS
As promised I have written a proper installation guide for macOS and Linux.

RE: PX41CX Firmware patch
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. https://calculator-scripts.sourceforge.i..._firmware/ Regards Martin https://uiq3.sf.net/rpn-45/ Developer RPN-45, FX-602P Simulator, FX-603P Simulator HP16C, HP35s, HP-Prime, FX-602P, FX-603P, PC-1403 |

RE: PX41CX screenshots
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:

RE: PX41CX
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:- Code: PX41 Ian HP-41CV HP-12C PX-15C PX-41CX HP-15C CE |

I'm currently working on a four-line display mode when in PROG mode.
If anyone is interested in testing it, please send me a PM. |

RE: PX41CX
As suggested by Alex, I have updated px41cx-utility to allow setting the date language of the firmware file.
Changes include: - specify firmware date language for English, French, German, Spanish, Italian or Portuguese - Display firmware date language with other firmware information - Display firmware version with other firmware information See the README in the Github repository above for more information. Please let me know if you have any issues or suggestions. Calculator Clique on YouTube |

RE: PX41CX - Pierre's Interface
Pierre's Interface (for Excel) is now very mature, and in some ways is now the most advanced way to program your PX41CX on BOTH Windows and Mac.
It supports compiling programs up to 1500 lines (DM41 Utility only supports 1000 lines) It can generate raw, bin and dump (.d41) files after compilation. It fully supports synthetic programming without needing any byte substitution gimmics. It can send and receive dumps to the PX41CX (on both Windows and Mac). It can fully decode a dump, or raw, or .bin file from either the PX41CX or DM41 calculator It can generate a Barcode print file for HP-41 users with the barcode reader. And it supports commands from the advanced ROM modules shipped with the PX41CX. It will happily use downloaded .txt programs, even those with line numbers and comments! Or you can copy and paste online code from the archives, or code libraries widely available. It now supports Mac versions of Excel from 2002 through to Excel 365, and all Windows versions of Excel. And it's free. |

Pierre has done an outstanding job with his 41CX Interface. Anyone using a PX-41CX, DM41L, DM41X, go41X or V41 must give it a try. I haven’t tested the Windows version yet, but it works perfect with Excel 365 on a MacBook Pro M3. |

RE: PX41CX
Moin!
I have been the happy owner of a PX41CX for 3 days now. Shipping from Mexico to Germany took only 3 days. But within Germany it was probably difficult... I am very excited about the device. I compare it in particular with the DM41X. I like the keyboard of the PX41CX much better. It is absolutely reliable, the force required is pleasant and there is a light click. I have switched off the key beep. The device feels like a palm flatterer in the hand. I really like the lettering, although the keys themselves are not labeled. If you hold the calculator almost vertically, you can see the alphabet particularly well, as if the letters were glowing. If you remove the battery, the memory is lost. This can be avoided by using the USB cable for the power supply. The display is crystal clear and extremely easy to read. There are so many positive things to report and I haven't discovered them all yet. I hardly use the DM41X at all. The keyboard and I are not friends. I've used the PX41CX more than the HP41CX since I got it. The device is simply fun. Thanks a lot, Alex, for this device! |

RE: PX41CX
Hi agarza,
Very interesting project, the main reason I'm interested is because I have tried to replicate the hp 45 in an 8051 mcu using Bascom compiler, after a great deal of work I have a rpn model. However, my compiler only supports 32 bit ieee 754 binary floats which are lousy at best and further more exponents are not displayed or cannot be entered. The reason I'm using the 8051 over the AVR is because the former supports bcd(low level) whilst the AVR does not. I'd be interested to know what floating point format you are using and whether you are coding in low level or you are using a compiler or both?, if you are using a compiler which one? Cheers Darren |

However, since the PX is emulating, it doesn't rely on the AVR's floating point routines. The AVR does have a half-carry flag, which helps with BCD arithmetic. |
