Write programs for PICs in C using SDCC and Code::Blocks on Linux

From Curuxa

If you prefer to use graphical development environments to write and compile your PIC programs in C on Linux, a good choice is Code::Blocks. These are the instructions:

System requirements

A working Linux installation
SDCC
gputils
Code::Blocks

Compilation

Setup Code::Blocks

These steps have to be done only once.

Open Code::Blocks
Go to Settings->Compiler and debugger...
Selected compiler->SDCC
Click on Set as default
Click on tab Toolchain executables
Make sure Compiler's installation directory has the correct path. It's usually /usr/bin

Create a project

Open Code::Blocks
File->New->Project
Category-> All categories
Choose Empty project
Click Go
Follow the instructions. On the last section you have to choose...
- Compiler: SDCC Compiler
- Uncheck Create Debug configuration
- Check Create Release configuration
Ignore the warnings about warning flags and optimization flags
File->New->Empty file
Save the new file (for example) as MyProgram.c into your project's directory
Write your program in C-language using SDCC syntax. See its documentation. Each Main Board and Module has some sample code you can use
Go to Project->Build options
Click on tabs Compiler settings->Compiler flags and the check [CPU] Microchip PIC 14-bit ... [-mpic14]
Go to tab Other options and write the parameter we have to send SDCC to choose your PIC model. For example if you are using a PIC16F887, you have to write -p16f887. Remember to put a dash at the beginning
Close that window
Now you can compile your program. Go to Build->Build

Now you've got a .hex file placed in [your_project_dir]/bin/Release. You can program/burn it into the microcontroller.
