LoCAD Hack 6.1 + Redeem Codes

This update fixes a bug regarding the language setting.

Due to the problem with the text display when rotating in portrait orientation, which occurred in some cases, the rotate function is omitted from this version and the Book button is inserted instead.
This can be used to display the text selected under ‚Settings‘.
By using Mac Catalyst, this iPad app can now also be run on a Mac. However, this reduces the signal speed.

This update speeds up the loading of complex circuits.

• This update fixes a switching problem at AND and OR gates that can occur in special individual cases when two similar signals arrive at two inputs almost simultaneously.

• In this version, the switching behavior of the tri-state gates has been made more realistic and a matching short-circuit detection has been integrated.
If two connected tri-state outputs are activated, where one output is on H and the other on L, a short circuit exists.
To avoid unclear line conditions, care should be taken with the improved tri-state gates to ensure that an active gate is first deactivated before a gate connected to the same line is activated.
A circuit containing previous tri-state gates will still work.

• A detection of problematic connections (interconnection of outputs of two gates) has also been integrated, which is activated in the operation mode.

This update prevents the program crash that could previously occur under special circumstances when the app was moved to the background after using the magnifying glass with the home button and later reactivated.

This update fixes the following issues:

• When deleting lines via the edit mode, possibly existing coupling diodes at vertical line sections are not removed. This does not affect the functionality of the circuit, but it looks irritating.

• When copying a section, an error occurs that can lead to a program crash.

In this version
• The problem with the dark mode, which is possible from iOS 13 and later, has been fixed.
Previously, activating the dark mode resulted in the meaningless setting "white font on white background“.
• The problem with the access rights caused by the change of the download procedure from iOS 13 and later has been fixed.

 The link "open in LoCAD" in the books "How computers work" and "Building a microcomputer" could not load the circuits from iOS 13 and later.
• Fixed the program crash that occurred from iOS 13 and later when pressing the button for displaying a book text in the "show in portrait orientation" section of the settings menu.

Due to the changes in the Books app, instead of displaying in portrait orientation, the 4-finger swipe to switch between book and LoCAD is provided for convenience.
• The access to iCloud Drive is realized.

Unfortunately, shortly after the release of version 4.4, the following problem with the NSSecureCoding protocol recommended by Apple and used from version 4.3 became known:
In versions prior to iOS 13, a circuit with a text object on the workspace cannot be loaded. The problem was fixed with this version.

After the enabled use of the switches during the signal run (since version 4.2) and some hints (many thanks for the feedback) the behavior of the coupling diodes was revised.
Now it is realized that a 1-signal of a coupling diode transmitted to the perpendicular line is maintained even if it was superimposed by a following 0-signal of another coupling diode.
In circuits without appropriate signal timing, the previous procedure led to the impression of a malfunction.

This update
• fixes the error that occurs under iOS 13 and later when sharing a circuit
• prevents a program crash when starting a circuit with illogical 1-states on some lines, which could have been caused by an unintentional interruption of the simulation run
• contains further stability improvements.

This update
• allows the activation of a switch during the signal run
• fixes the error that occurs when switching off the continuous pulse when set to independent clock puls..

This update fixes a bug in the short circuit detection algorithm.

This update contains
• an improvement in IC creation.
• a change in the algorithm to speed up the switching process
• bug fixes and stability improvements
• a link to the book "Building a microcomputer - From basic circuits to a programmable computer"

This update fixes an issue that may occur in edit mode that may cause the program to crash.

This update
• fixes an error that can occur when viewing nested ICs
• adds the missing crosshairs in the magnifier
• fixes a moving error of the magnifier with a larger workspace
• fixes a problem with accessing the photo library for a circuit shot

In this version
• when switching off the operation, all lines are “current-free“
• the line elements that may protrude beyond the grid points are automatically removed when the cutting process is terminated.

This simplifies further editing/changing of a circuit.

This update includes
• an activity indicator for the signal run
• an improvement of the signal display in ICs when using the clock generator and with deep nesting
• a change in the sequence of the basic elements (adaptation to the Mac version)
• the delay button is moved to the right next to the on/off button
• bug fixes and stability improvements

This update includes
• an improvement of the user interface (toolbox)
• a revision of the algorithms for creating and viewing ICs
• a simplification for testing circuits (Lines can now also be set to the other state by tapping on the line beginning without a switch having to be present there)
• an improvement of the section editing
• bug fixes and stability improvements
• further small program improvements

• The book "How computers work - Introduction to basic principles of computer hardware" announced in version 2.1 is now available in the Book Store. Among other things, it explains how the individual components can be interconnected to form functional units. In the submenu of LoCAD it can be viewed in extracts or purchased directly.

• Minor bug fixes and stability improvements.

• Minor bug fixes and stability improvements.
• To simplify the exchange of circuits between the MacOS and iPad versions, the text objects have been adapted.

• Adaption for iPad Pro.
• Improvement and simplification of the interior view of an IC. A step back is now also possible with a touch on the circuit.
• To adapt to the MAC version, individual input and output designations have been adapted for some components (HA, VA, MUX, DMUX).
• Further components are available
- for the basic elements: tri-state gate and delay element
- for the block elements: Binary counter and 16 x 4 bit RAM
• The explanatory note "How do computers work? - Introduction to the basic principles of computer hardware" is currently in preparation. It explains how the individual components can be interconnected to form functional units.

• A problem with drawing and deleting lines has been fixed.
• With the share extension, files can be stored in a cloud memory or distributed via AirDrop.

• A problem with the color of the "Edit" and "Done" menu items in iOS 11 has been fixed.
• Corrected the orientation of the tutorial when starting the program in portrait orientation.

- The last update did not fix the problem with the photo button for all devices. But it should now work on all devices.

- Fixed a problem that could occur when an IC filename contains a leading space.

Fixed a problem with the photo button.
