New OS Update for Casio Classpad II

New OS Update for Casio Classpad II

Per TIPlanet:  Casio has released a new OS version (2.01.7002).   Among the changes includes the new off-screen when the Classpad is turned off with Casio's new logo "Boost Your Curiosity".  

The updates do not include the Python programming language (I don't think).

The calculators included are the fx-CP400 and fx-CP500.

HP Prime Python: Complex Number Arithmetic and Lambert Function - and Firmware Update!

 HP Prime Python:  Complex Number Arithmetic and  Lambert Function

HP Prime Python:  Complex Number Arithmetic and  Lambert Function - and Firmware Update!

Firmware Update!

There is a new firmware update (10/1/2021) - v. 14596 for both the Hardware versions (Version 1 and Version 2) of the HP Prime.   The link to the MHPoC entry and download links:  

HPMoC Thread:

https://www.hpmuseum.org/forum/thread-17538-post-152707.html#pid152707

HP Prime Hardware 1 Download:

https://www.hpcalc.org/details/7469

HP Prime Hardware 2 Download:

https://www.hpcalc.org/details/7783

Now on to complex numbers and the Lambert function.

Python File Introduction

A work around of having separate Python files is to create separate apps for each application.  Both applications are available to download at the blog. 

Complex Number Arithmetic

The HP Prime App "Python-Complex Arithmetic" performs the four arithmetic functions on two complex numbers.

Script:

from cmath import *

print("Complex Number Arithmetic")

x1=float(input("real_1: "))

# input values are not auto printed

print(x1)

y1=float(input("imag_y: "))

print(y1)

z1=complex(x1,y1)

print("z1 = "+str(z1))

x2=float(input("real_2: "))

print(x2)

y2=float(input("imag_2: "))

print(y2)

z2=complex(x2,y2)

print("z2 = "+str(z2))

print()

print("z1 + z2 = "+str(z1+z2))

print("z1 - z2 = "+str(z1-z2))

print("z1 * z2 = "+str(z1*z2))

print("z1 / z2 = "+str(z1/z2))

Example:

x1 = 9

y1 = -8  (use [ +/- ] to enter negative numbers)

x2 = -1

y2 = 4

Results:

z1 = 9-8j

z2 = -1+4j

z1 + z2 = 8-4j

z1 - z2 = 10-12j

z1 * z2 = 23+44j

z1 / z2 = -2.411764705882353-1.647058823529412j

Lambert W Function

The HP Prime App "Python-Lambert W Function" approximates the Lambert W function.   The Python script estimates w given complex number z using Newtons Method:

w * e^w = z

Script:

from cmath import *

print("Lambert W Function - approx")

print("w * exp(w) = z, find w")

zr=float(input("z_real: "))

print(zr)

zj=float(input("z_imag: "))

print(zj)

z=complex(zr,zj)

w0=complex(1,1)

w1=complex(1,1)

while abs(w1)>1*10**-10:

 w1=(w0*exp(w0)-z)/(exp(w0)+w0*exp(w0))

 w0=w0-w1

# round low parts to zero

# z.real, z.imag are read only

wr=w0.real

if abs(wr)<1*10**-10:

 wr=0

wj=w0.imag

if abs(wj)<1*10**-10:

  wj=0

w0=complex(wr,wj)

  

print("w = "+str(w0))

Example:

Input:  -1.57079362679 (about π/2)

Result:  approx -1.223152769062088e-06+1.57079554811127j  

Input:  2+3j

Result:  approx 1.090076534485791+0.5301397207748389j

Firmware Update: Swiss Micros DM42 - DMCP 3.21/DM42-3.19, Free42, and Offscreen Images

Firmware Update:   Swiss Micros DM42 - DMCP 3.21/DM42-3.19, Free42, and Offscreen Images

Firmware Update

Swiss Micros released a firmware update to the Swiss Micros DM42 calculator.  The current versions are:

* DMCP 3.21

* DM42-3.19

Download the file here:

https://technical.swissmicros.com/dm42/firmware/

This firmware brings the DM42 in alignment with Firmware 3.0.3 of Free42 by Thomas Okken.  Click here for details:

https://thomasokken.com/free42/history.html

Furthermore, you download the latest version of Free42 here:

https://thomasokken.com/free42/#doc

Steps:

1.  Plug in the DM42 into the PC.

2.  Activate USB Disk.  Press [ shift ] [ 0 ] (SETUP), 1. File, 3.  Activate USB Disk.

3.  Transfer the file (see Tip below) to the root directory of the calculator (hardware).

4.  Exit USB Disk on your calculator.  The firmware should update itself automatically.

Detailed instructions and other ways to update firmware can be found here, refer to sections 6.2 for the quick update or 6.3 for an alternative method:

https://technical.swissmicros.com/dm42/doc/dm42_user_manual/#quick_update_guide

Tip:  When transferring the bin file to the calculator, you want to transfer the combination bin file DCMP_flash_3.21_DM42-3.19.bin.   You need both the DCMP and DM42 files for the calculator to run.   

New Comparison Functions

X=?, X>?, X<?, X≤?, X≥?, X≠?

These tests compare the contents of the X Register to any other stack (T,Z,Y,L) or variable.   

Example:

R01 = 33

X:  25

X>? 01 returns No (next program step will be skipped)

X<? 02 returns Yes (next program step will be executed)

0=?, 0>?, 0<?, 0≤?, 0≥?, 0≠?

These tests are similar to the above except this comparison of any target stack or variable to zero.   

Both can be found in the CATALOG-PRGM menu.  In CATALOG, scroll to the PRGM submenu.

Writing Program Lines with X2LINE and A2LINE

Found in the CATALOG-MISC menu, X2LINE and A2LINE creates a program line from the X-stack and Alpha register, respectively.  This allows the user to create program lines outside of the program editor.  I don't know how this can be effective when it comes to executing functions, but they are here.

Enhanced VARMENU Command

The VARMNU1 allows the user to select variables without having to assign values to other variables first.  Found in the CATALOG-PRGM menu.

Longer String Creation with XSTR

I think this going to be my new favorite command besides the new comparison functions.  The XSTR allows for creation of strings of any length, beating the six-character limit of ASTO.  Found in the CATALOG-PRGM menu.

Example:

CLA

XSTR "FREE 42/DM 42"

ARCL ST X

XSTR " 2021"

ARCL ST X

Alpha Register:  "FREE 42/DM42 2021"

Off Images for the DM42 and DM41X

Off images must be the size of 400 x 240 pixels and be 1-color (monochrome) .bmp files.
