Besides from the compiler you also need to take into consideration the IDE. Microsoft Embedded Studio or something like that is excellent if you're already used to the Visual Studio 6 methodology of writing c code.

Using Large Data Arrays in Microchip C18 Compiler

I'm going to try Microchip C18 compiler first and then I'll swallow hard and get HighTech which seems pretty solid from reviewing the trial version and samples. To avoid messing with the default linker script, take a copy of it and place it in your project folder, then mlcrochip it to the projects list of files. Fortunately, it is easy to modify comiler standard linker definitions to create a data bank large enough to hold a variable or array much larger than bytes.

Perfect for professional use. Micfochip Embedded Studio or something like that is excellent if you're already used to the Visual Studio 6 methodology of writing c code.

You may be able to purchase one from here: I have been using CCS for many years. PetPaulsen 2, 2 2 gold badges 17 17 silver badges 30 30 bronze badges. So all in all I'm feeling quite a bit better about my choice of tools. Here is the complete file.

Haven't received registration validation E-mail? Notice that bank gpr15 is only 0x5F 96 bytes in size, this would have given us a total of bytes - perfect. PIC-compiler, mikroC is gr8!

You cannot allocate variables which are larger then bytes without editing a linker script. Are you referring to Microchip's compiler? Dario Solera Dario Solera 4, 3 3 gold badges 25 25 silver badges 33 33 bronze badges. It really depends on the size of the project you are working on.

If a compiler vendor really wants to be nice, allow pointers to accept bank qualifiers, so that a pointer which would only ever point to things in a certain psect could be stored in 8 bits. All automatic variables and parameters throughout the program must fit in a byte page they are allocated statically at link time.

Well, the code size sure seems smaller than the competition. Asked 11 years ago. Here is the compileer linker script for this microcontroller. Please note that because our array is chars, you will need to use an int not a char as the index variable.

Global and static ints and structs, and arrays thereof, whose size ranges from bytes will each be allocated into psects on a per-module basis; each module's psect must fit in a byte page.

I think most people that decide to go with Microchip C18 compiler only because fompiler see it when they go to the microchip website and are already familiar with MpLab from doing assembly which is a terrible IDE IMHO. You have to specify which ram bank to allocate variables to.

C18 worked much better, but still had problems. Michael Michael 1 1 gold badge 9 9 silver badges 24 24 bronze badges.

Jessica Shaw I am looking for C18 version 3.

In order to have const string be allocated to Program space instead of ram you have to use the rom keyword. If you do not have your original C18 compiler release CD you may have to buy it from old stock or search the internet for some kind of hack. While I appreciate not having to hand-place all variables into banks, the rules used by HiTech's compiler are annoying, bizarre, and goofy. Stack Overflow works best with JavaScript enabled. Be aware that the C compiler may also put variables in our data bank.
