JimP, I'll get back to you once I've identified the build required.
Thanks

I've looked at the links above and found the two calc_full.bin files, both showing as Revision 3905. I understand each file holds the complete build code information for the flashing procedure. Unfortunately I don't understand the differences between these versions sufficient to choose which file to apply to the programming task.

Up until four weeks ago, I was not aware of the WP 34s project. I came across it during a web search for a Tanh-Sinh numerical integrator. Dr Google brought me to the forum, and specifically to the T-S program developments provided by forum member emece67. The forum posts were dated early in 2017. Pauli confirmed the Tanh-Sinh program would be added to the next build.

I was fascinated by the WP 34s project overall, and managed to purchase a new HP 30b calculator. Forum members assisted my search for information describing the manner in which the HP 30b could be programmed via the HP flash cable and other connection methods (hand-made connectors, USB interfaces, the clock crystal and IR diode modifications, etc). It was at this point that I sought assistance with the programming task as I could not find any of the HP cables available, and both Pauli and JimP generously offered to assist me. Thank you both again.

At this point, the only thing delaying the calculator programming task is for me to determine which build file to use, as raised above by Jaco@cocoon-creations.com. Also, I've been unable to locate the emulator file sets for these two builds for running as an executable under Windows. Do the emulators contain the code for the build in a form which is viewable as RPN code lines in programming mode, or are the programs in the build always hidden from view in both the emulators and the physical calculator, and only accessible as functions called by their global label names? I'm unsure how to obtain the emulators or even what I need to obtain to try them!

Re the Tanh-Sinh program by emece67. Is this program contained in the two Revision 3905 calc_full.bin files? iF so, I'm still not sure how I make the choice between them due to insufficient knowledge of the WP 34s program development environment and build procedures, and the build differences between them. If the T-S program is in only one of those files, perhaps someone would be able to let me know which one.

Sorry for these very basic questions about the WP 34s project. Unfortunately, as an absolute beginner with the WP 34s, I very much don't know what I don't know!! Given the several-years time line of the project, my period of association is a dot at the far right end! Thank you for your patience and assistance. I still have a lot of knowledge and understanding to gather.
Regards


No expert here, but I would suggest to navigate up on each of the two url's up by clicking on the 1st row ("..") until you see a folder named "docs".
In the docs folder there is information that may answer some of the questions.

It seems that the 1st URL is a variant for complex lock mode that several members here found useful when compared with the standard "official" release found in the 2nd URL.

Also binaries exist for the different hardware variants (standard unmodified hp 20/30, installed xtal, installed ir port).

Concerning the t-s function, I would check again the docs folder in the standard official release, as it seems a pdf user guide is included as well, although I don't know if it is the approved official user guide. The later should be obtained from Walter. He used to distribute the latest edition on paperback. I believe he distributed a pdf format as well in the past.

Additional note on t-s integration:
Have a look to the source code for the standard official build:
http://svn.code.sf.net/p/wp34s/code/trunk/xrom/

One integrate.wp34s file is listed. Opening it and for me it looks like this ican be the t-s function you are looking for:


// Double Exponential Integration for the wp34s calculator
//
// v1.4x-412 (20180312) by M. C�sar Rodr�guez GGPL
//
//
// Remarks:
// - accepts +Infinite and -Infinite as integration limits. If none
// of the limits is infinite, the method applied is the tanh-sinh
// one. If both are infinite then the sinh-sinh method is selected.
// Otherwise the exp-sinh method is used.
