- - Char 1 - Driver (A-4988, T-TMC220X)
- - Char 2 - Z Stop(B-BLTouch, E-Endstop)
- - Char 3 - Screen(L-LowRes, H-THighRes)
- - Char 4 - Bed (A-AC, D-DC)
- - Char 5 - Endstop(O-Optical Y, M-Mechanical Y)
- - Char 6 - Extruder (T-Titan, B-BMG, L-LGX, S-Basic)
+This branch adds support for the Creality touchscreen machines and was split off from the standard Creality branches due to specific custom changes not found upstream. This includes extensions to the EXTui framework among other smaller tweaks that we have been working towards getting submitted upstream. Machines supported here are :

+Ender 3V2 has a dedicated file set. CR10 Smart has a dedicated high resolution screen set. Portrait displays use the CR6/E3 Touch variant and landscape use the combined set.
+
+Screen files are archived with [7-Zip](https://www.7-zip.org/) simply because it came out 1/5 the file size of a zip file. That added up fast!
+
+There is a limitation with Windows systems and path depth so the file names need to be shorter than we would prefer. If you get an error compiling due to the path limit, move the folder to the root of your hard drive. Here is a legend to help decode the files:
+
+- BLT = BLTouch
+- BIL = Bilinear Leveling
+- UBL - Unified Bed Leveling
+- DZ = Dual Z Steppers
+- Fil = FilamentRunout
+- Slnt = Creality Silent Board
+- H = E3D Hemera Extruder
+- MC = Mosquito Creality mount
+- ME = Mosquito E3D mount
+- Melzi Host option disables local SD card to allow more features and buffer for Octoprint control
+- NF = Noise filtering for machines with cable extensions - reduces homing accuracy!
+- LR = Stock runout replaced with Lerdge
+- ZM = BLTouch connected to ZMin port instead of Probe pin 5 connector harness

 Insanity Automation Discord - https://discord.gg/TKmJ85PyG4

+## Primary Notes for DW7.4.8
+   - Added Linear Adv and Input Shaping Screens
+   - Signifigant improvement in response times following changes to new generation machines
+   -- The DWIN OS 3.5 had an option to enable NOACK with an addon bin file. 4.0 has a specific throttled response OS revision. 4.5 needed a totally different UI image flashed. No way it could all live together without completely confusing users so we set about figuring out how to keep universal support and found a balance in data send cycles that the 2560 buffers could still handle the replies without overunning.
+   - Added support for changing runout sensor type on the LCD
+   - Added toggle to change babystepping increment on the LCD
+   - Thanks to EvilGremlin for some of the icon and display graphics work
+
 ## Primary Notes for DW7.4.7
   - Added IDEX screens
-   - Added Branch / support for Tenlog IDEX machines with LNL Solutions
   - Fan adjustment now numeric instead of simple on/off
   - Tap Z offset on adjustment screen to type numeric value
   - Sync to 2.1.2 with LA now on for all builds, Silent specific builds eliminated

+# Testing Marlin
+
+Marlin included two types of automated tests:
+- [Build Tests](../buildroot/tests) to catch syntax and code build errors.
+- Unit Tests (this folder) to catch implementation errors.
+
+This document focuses on Unit tests.
+
+## Unit tests
+
+Unit testing allows for functional testing of Marlin logic on a local machine. This strategy is available to all developers, and will be able to be used on generic GitHub workers to automate testing. While PlatformIO does support the execution of unit tests on target controllers, that is not yet implemented and not really practical. This would require dedicated testing labs, and would be less broadly usable than testing directly on the development or build machine.
+
+Unit tests verify the behavior of small discrete sections of Marlin code. By thoroughly unit testing important parts of Marlin code, we effectively provide "guard rails" which will prevent major regressions in behavior. As long as all submissions go through the Pull Request process and execute automated checks, it is possible to catch most major issues prior to completion of a PR.
+
+## What unit tests can and can't do
+
+Unit tests can be used to validate the logic of single functions or whole features, as long as that function or feature doesn't depend on real hardware. So, for example, we can test whether a G-code command is parsed correctly and produces all the expected state changes, but we can't test whether a G-code triggered an endstop or the filament runout sensor without adding a new layer to simulate pins.
+
+Generally speaking, the types of errors caught by unit tests are most often caught in the initial process of writing the tests, and thereafter they shore up the codebase against regressions, especially in core classes and types, which can be very useful for refactoring.
+
+### Unit test FAQ
+
+#### Q: Isn't writing unit tests a lot of work?
+A: Yes, and it can be especially difficult with existing code that wasn't designed for unit testing. Some common sense should be used to decide where to employ unit testing, and at what level to perform it. While unit testing takes effort, it pays dividends in preventing regressions, and helping to pinpoint the source of failures when they do occur.
+
+#### Q: Will this make refactoring harder?
+A: Yes and No. Of course if you refactor code that unit tests use directly, it will have to be reworked as well. It actually can make refactoring more efficient, by providing assurance that the mechanism still works as intended.
+
+#### Q: How can I debug one of these failing unit tests?
+A: That's a great question, without a known immediate answer. It is likely possible to debug them interactively through PlatformIO, but that can at times take some creativity to configure. Unit tests are generally extremely small, so even without interactive debugging it can get you fairly close to the cause of the problem.
+
+### Unit test architecture
+We are currently using [PlatformIO unit tests](https://docs.platformio.org/en/latest/plus/unit-testing.html).
+
+Since Marlin only compiles code required by the configuration, a separate test binary must be generated for any configuration change. The following process is used to unit test a variety of configurations:
+
+1. This folder contains a set of INI configuration files (See `config.ini`), each containing a distinct set of configuration options for unit testing. All applicable unit tests will be run for each of these configurations.
+2. The `Marlin/tests` folder contains the CPP code for all Unit Tests. Marlin macros (`ENABLED(feature)`, `TERN(FEATURE, A, B)`, etc.) are used to determine which tests should be registered and to alter test behavior.
+3. The `linux_native_test` PlatformIO environment specifies a script to collect all the tests from this folder and add them to PlatformIO's list of test targets.
+4. Tests are built and executed by the `Makefile` commands `unit-test-all-local` or `unit-test-all-local-docker`.
