Lets add some pre-made files: right click on the Source Files folder and choose New-Other Select Microchip Embedded-SDCC Compiler-main.c to create an example main file Youll get the following code: Dont worry about the warnings MPLABX give on the interrupt 1 and interrupt 2 keywords.I really like to thanks Eduardo Casino and Volker Schilling-Kstle and the people from microchip forum (mainly on this thread ) Hope you all enjoy it.
Legacy Peripheral Libraries For Mplabx Free Programming ToolchainsIntroduction The main objective of this project is to promote the use of free programming toolchains for anyone. When Microchip first shipped MPLABX, based on netbeans I thought it would be really great if we could join all three and distribute a complete IDECompilerProgrammer which can run on any operating system, at least on the three major ones (win, linux, mac). With the help from Microchip developers the SDCC toolchain plugin was developed. So any doubtsproblemsbugs on the plug-in can be sent to me (rmaalmeida gmail. If you want to help improve the plug-in just enter in contact. It is possible to use SDCC and GPUTILS on MPLAB 8.XX, although it is a little buggy. Legacy Peripheral Libraries For Mplabx How To Setup MPLABIve a guide on how to setup MPLAB 8.XX and SDCC available in Portuguese. Installation The toolchain needs 2 programs to be downloadedinstalled ahead SDCC and GPUTIS. The compiler can also generate code for other architectures besides PIC16 and PIC18, but it is not addressed in the plug-in. The GPUTIS is a collection of GNU tools to link and generate machine code from the ASM files. The installation is pretty straight forward, just download the setup and run. They maintain versions for WinLinux (SDCCGPUtils), and Mac (SDCC only). But you can download the source code and configure make make install them. If installing in windows double chech if Add C:Program Filesgputisbin (for gputils) and Add C:Program FilesSDCCbin (for SDCC) are checked at the end of the installation. This is really important for them to communicate with MPLABX. After installing both tools, open the MPLABX go to Tools-Options-Embedded-Build Tools, and press Scan for Build Tools, the MPLABX should be able to retrieve information from all the installed toolchains: Just make sure that the SDCC version is visible after the SDCC Toolchain entry. In the picture I was using 2.9.0. Otherwise go manually to set the Base Directory. Remember that the base directory is the bin folder inside the directory you choose to install the SDCC compiler not the GPUTILS. If the scan does not works, try uninstall SDCC and GPUtils and reinstalling them making sure to add their directories to the PATH. If youre using the SDCC compiler from versions 3.0 onwards you need to check the Use non free libraries option. This is done after creating a new project go to File-Project Properties- Conf:default-SDCC Toolchain-sdcc-Option categories-General: Creating and compiling a new SDCC project with MPLABX: This example was made using SDCC 2.9.0, GPUTILS 0.14.0 and MPLABX beta 7.0. ![]() Note that MPLABX will create a directory with.X extension automatically for the project. Another point to pay attention is encoding, mainly if youre going to use non ASCII characters as accents or other non-English letters.
