Forum Index : Microcontroller and PC projects : Setting a default "OPTION" when compiling MMBASIC

Hi, I am about to recompile MM-BASIC to make some customisations to the source code, and I would like to alter the default "OPTIONs" that the device starts new-born with. For example, I wish to have my device already have "OPTION KEYBOARD US", "OPTION LCDPANEL CONSOLE" and "OPTION LCDPANEL SSD1963_5 ..." configured. It is not a big issue, but I expect to compile MM-BASIC multiple times to get my customisations working, and I don't want to hassle with USB-ing to a PC every single time to set up exactly the same thing time and time again. Where in the source code (using the "MicromiteSource.zip") is where I can set my default OPTIONs? I am having great trouble finding it/them. Cheers, |

Instead of a re-compile, take a virging MM, make the changes you like then read the flash back into your IDE and save it as your standard build MMBasic I think the options are included - the basic program is |

Thanks for the reply. My intent is to make some changes to the LCD "SSD1963_5" code, but that will likely take me several attempts to get it right. From what you say, I should read just the flash where the options are stored (after setting my option parameters) and write it back after re-flashing the MM-BASIC code itself...? I'll have to check out the memory map (if there is one) that shows the separation of the MM-BASIC firmware and where the OPTIONs are stored. I thought they were in the same block, but...

Get a virgin MM, make your changes (even upload a prog too if you like, with stuff in the library etc...) then just read back the entire memory image and save it as a HEX file. No need to hack the memory to bits - just snag the whole lot - basic prog will become part of the HEX image too, options, everything. this then becomes your customised build. Take a look at the section "Single, Secure HEX File" on page 16 of the Micromite User Manual. I think this will probably do what you want without all the pain of a recompile.

@CaptainBoing Thanks for the suggestion & your assistance, but I will need to recompile because I want to make changes to the BASIC interpreter itself. I could possibly write a Cfunction to do what I want, but my changes are a long way down (as in almost at the base level - altering one or more of the defines/constants in "SSD1963.c" to use a different screen SSD1963 with 'super wide' 800x320 LCD panel ). The changes have nothing to do with the BASIC program that sits on top. @matherp Thanks for the pointer - I found a map of how the flash memory is used, but sadly no hint on where the OPTIONs get stored. Perhaps I'll have to trace a particular OPTION and find out where it gets put... Cheers, |
