(Travis CI status)

CESE, FI-UBA project template for CIAA-NXP / EDU-CIAA-NXP

CESE, FI-UBA: http://laboratorios.fi.uba.ar/lse/cursos.html

IMPORTANT

This environment is under construction!!

Always use the released versions because in these all examples are tested and the API documentation is consistent. The master branch may contain inconsistencies because this environment is currently under development. See the Travis CI tag above to know the status of this repository.

Available libraries:

• CMSIS 5.4.0 (Core and DSP).
• LPCOpen v3.02.
• sAPI v0.5.2.
• FreeRTOS Kernel V10.0.1.
• LPCUSBlib.
• Elm-Chan FatFS. Support for SD Cards (SSP) & Pendrives (USB MSD).

Supported boards

• CIAA-NXP (LPC4337).
• EDU-CIAA-NXP (LPC4337).

Supported toolchains

• gcc-arm-none-eabi

Usage

Make sure you have an arm-none-eabi-* toolchain configured in your PATH. If you don't have it, download GCC ARM Embedded.

• Define PROJECT_NAME and PROJECT_PATH variables in project.mk according to the project you want to compile (PROJECT_PATH is relative to this folder, leave void if the project is in this folder).
• Compile with make.
• Clean with make clean.

Make sure you have an openocd configured in your PATH.

• Download to target via OpenOCD with make download.

Create a new project

Each project consist in a folder (with a non-spaces name) that includes inside 2 folders, one named src (here go, .c, .cpp or .s source code files), and another one named inc (here go, .h or .hpp source header files) and one file named config.mk, where you may configure which libraries you include and compiler options.

Add a new library

The libs folder allow you to include 2 types of libraries:

• Simplie library. Consist in a folder (with a non-spaces name) that includes inside 2 folders, one named src (here go .c, .cpp or .s source code files), and another one named inc (here go .h or .hpp header files). This kind of library compiles automaticaly by the Makefile.
• Advanced library. Consist in a library whit a complex folder and files strcuture, i.e. LibUSB. This case reuire make your own makefile. You can inspire from sAPI makefile to do that.
