FLOW CODE AND C COMPILING IN MPLAB

[miguelmauricior]

Hello Ben,
I have a problem when I compiled the program in C. I used the HI TECH 9.6 compiler and when I tried to build the code this is the error MPLAB showed me:
Error [141] C:\PIC PROJECTS\SENSOR MAGNETICO.C; 23.19 can't open include file "system.h": No such file or directory

Then I double clicked in the error and the problem is in this line which is generated by FC:
#include <system.h>

Can you tell me what it is wrong? or what I am doing wrong?

I you need I can send you and image of the problem.

Let know please.

Thanks.

Hello

If you are moving the C code from Flowcode across into HI Tech C then you will have to do something called porting. This is essentially modifying the C code to allow it to work with the new compiler. This process can be a little tricky and requires a good working knowledge of C.

The system.h file simply sets up things like a few definitions and clock speeds etc.

Im afraid I have never used the HI TECH compiler so I will not be able to shine any light for you. Can I ask why you are using MPLAB if you do not have BoostC for it?

Hello Ben,

Can you be more specific. Let tell you that I am trying to do the same thing I did with the assembler, and despite I am not an expert in this area I supposed this tool would worked in the same way that MPASM did under MPLAB but certainly it did not. But if there any other way to get the same result please let know.
Anyway I use with MPLAB because as you know I have the PIC START and it came with a basic HITECH software.

I found a file called BOOOSTC which came with the FC software. Is this a basic C compiler software? Anyway I tried to run the software but in DOS windows appears an error that it says: Compiler can not be started with out a host program <code 118> this happens with PIC 16 and 18 so in this case what I must do?

Thanks.

To use BoostC with MPLAB, you need to buy a separate license for it.

To use HiTech C compiler, you need to "port" the C code from Flowcode to it. This is possible, but you would need to be fairly proficient in C.

Hallo Steve

I have a full version of boost-c compiler,but i have not a flowcode v3 c-file compile without an error.
It is not so easy,is there a example for the settings in the project-box?....

Hello Wolfgang

Ok firstly we have to setup MPLAB to use the BoostC compiler.

1) In MPLAB use the Project menu and select "select language toolsuite"
2) Set the active toolsuite to use the BoostC C Compiler for PIC16 / 18 depending on your target, click ok.
3) Use the Project menu and select "select language tool locations"
4) Expand the BoostC Compiler for PIC16
5) Check that the locations exist for the linker and compiler and search paths. The locations should point to files within your Sourceboost folder.

Linker - C:\Program Files\SourceBoost\boostlink.pic.exe
Compiler - C:\Program Files\SourceBoost\boostc.pic16.exe

Assembler Include - C:\Program Files\SourceBoost\include
Include - C:\Program Files\SourceBoost\include
Library - C:\Program Files\SourceBoost\Lib
Linker Script - C:\Program Files\SourceBoost\include

Then to create your project in MPLAB you will need to do the following.

1) Using Flowcode create your program and compile to C.
2) Open MPLAB and click on the Project Menu and click New.
3) Give the project a name and select a directory on your hard drive to store the project.
4) Click on Project menu and select Add files to project
5) Select your C code file created by Flowcode
6) Click on Project menu and select Add files to project
7) Select the internals.h file located inside the "Flowcode vX/FCD" folder
8 ) Click on Project menu and select Add files to project
9) Browse to the "Sourceboost/Lib" folder, type *.* into the File name parameter box and press enter, now select the "libc.pic16.lib" file and click open
10) Use the configure menu and select "select device" to specify your target microcontroller
11) Use the configure menu and select "configuration bits" to specify the microcontrollers configuration settings.
12) Use the Project menu and select Build to compile and create your source code files.

For the attached example project to work you must extract it to the root of your C drive. This will give you a folder with the path "C:\Example"

Hallo Benj

Thank you for the great help!!!!!!!!!
The example works inflowcode > mplab 8.33 with boost-c 6.95 ok.
Tomorrow i test my project with a 18F8722.

Hallo Benj

For my object i add:

source files : sa_ecio.c
header files : internals.h
library files : libc.pic18.lib

if i compile , i have:

Clean: Deleting intermediary and output files.
Clean: Deleted file "sa_ecio.OBJ".
Clean: Deleted file "D:\sachs_work\ECIO\V4\sa_ecio\sa_ecio.HEX".
Clean: Done.
Executing: "C:\Program Files\SourceBoost\boostc.pic18.exe" sa_ecio.c -O1 -W1 -t 18F8722

Hello Wolfgang

Great glad you got it working correctly., Sorry I forgot the floating point library include in my above post.

This should be all you need now as all of the Flowcode components etc are dragged into the main C code file so other files are not needed.
