EASYMODE ~~~~~~~~ Version 1.00 RISC OS 3+ only and !NewLook compatible Written by G.J.Lee This program is Public Domain. Purpose ------- The purpose of this application is to allow the easy editing and creation of multiple screen mode extension modules. It is for people who perhaps already know how to create a mode extension module from scratch but who want the parameters required laid out in easy to edit fashion. The reason I wrote this program was because I wanted a mode editor whereby ALL the necessary parameters required to build a new mode could be fine tuned from the lowest level to my requirements. I felt that the high level approach of specifying the only the screen width, height, eigen values and pixel rates was indequate. I also wanted the created module to be able to cope with more than just one mode. How To Use ---------- Interactive help via !Help is provided so if you're confident, you don't need to read on but there are some subtle features that need to be pointed out. List formats should be zero, or one when using extended parameters. Specify a RISC OS base mode (0-63) so that all unused parameters will default to the value used for that mode. Now customise your new mode accordingly. If you want to test the mode then click on TRY MODE, if the screen goes haywire then Escape should reset the screen back to the configured wimpmode if you're lucky. You can also see the immediate effect of the VIDC parameters only, in the current mode, by clicking on VIDC ONLY. A useful feature is that you can see the VIDC changes in real time by holding Shift down whilst clicking on the arrows. Note that the display start/end values are also adjusted in real time to keep in touch with the logical screen size and the mouse pointer will become relatively offset, so use TRY�MODE periodically. A rough validation check on all values is carried out as they are altered because they all have their maximums and minimums and some can only be odd or even or be a multiple of something. You can validate/evaluate any particular value by pressing Return on it, use Tab or cursors to move between icons if you don't want this to happen. Loading And Saving ------------------ You can drag a module into !EasyMode to see if it can handle any screen modes itself. The information is extracted from the module by temporarily loading it into the RMA and repeatedly calling its service code handler, if it exists, directly with appropriate values. There is a slight risk when doing this of course, because the module hasn't been initialised so the call is unreliable but I figured that the risk is worth taking but worth mentioning. To see the list of modes currently stored, go to the submenu Main.Edit and choose a mode. Note that modes are MERGED when loaded not replaced, you can delete unwanted modes via Main.Delete. When saving your module, only the modes that have been ADDED to the list are used, NOT the one currently being edited. Add a mode to the list via Main.Add. Note also that the saved module is created using the information gathered, so if you load a module which wasn't created with !EasyMode in the first place, make sure that the module didn't perform any other useful functions before overwriting it. Miscellaneous ------------- The current frame refresh rate in Hz can be calculated and viewed via the submenu Main.Frame Rate. Remember that modes 0 to 63 are reserved for RISC OS so only add as one of these modes if you want to replace it. Modes 64 to 95 are for applications and 96 to 127 are for the user. Example modules are given in the subdirectory !EasyMode.Examples. Either drag them into !EasyMode to edit them or double-click on them and find out via *Help which modes they support. Limitations ----------- The VIDC control register cannot be used as a parameter, but you don't need to use it anyway if you correctly specify the base mode and use the extended parameters. Interlacing and sync can be controlled via *TV and Configure. Sensible values will have to be worked out by yourself because explaining in detail what each one does is beyond the scope of this document. If you don't know what a parameter does, just leave it blank at first. See the bibliography for where to get further information. Modes can only be defined for one particular monitor type, whereas the PRM states that mode extension service code is allowed to return different VIDC parameter lists for different monitor types but must always return the same Mode Variables. The test mode used is mode 127 so beware of clashes. If you get an error 'Bad Wimpmode' it means that the Wimp Manager doesn't like the mode variables so you could try typing MODE 127 from BASIC instead to try it out.
