Avr Gcc Download Mac

Posted on by admin

Dec 28, 2011 Download and install WinAVR, which includes the AVR-GCC toolchain together with some other useful tools for programming the AVR processor series. WinAVR is actively maintained and has the latest patches as well as some improvements of its own (like the -format=avr option for the avr-size tool). To program AVRs in Mac OS X, you will need the free avr-gcc compiler, avr-libc, AVRDUDE, and other associated tools. Download the CrossPack for AVR Development, which is packaged as a.dmg file. Open the.dmg file, and double-click on CrossPack-AVR.pkg. This document contains instructions to build AVR and ARM cross compilers on Mac OS X from source packages. Note, that precompiled binaries are available in our download area. So far, only the ARM toolchain had been tested on Leopard, running on a PPC.

This section explains how to program our 32U4 family of boards using the avr-gcc toolchain and AVRDUDE. This section is intended for advanced users who do not want to use the Arduino IDE as described in the previous section.

Getting the prerequisites

If you are using Windows, we recommend downloading WinAVR, which contains the avr-gcc toolchain and a command-line utility called AVRDUDE that can be used to upload programs to the A-Star bootloader. If the version of GNU Make that comes with WinAVR crashes on your computer, we recommend using the Pololu version of GNU Make.

If you are using Mac OS X, we recommend downloading the CrossPack for AVR Development.

If you are using Linux, you will need to install avr-gcc, avr-libc, and AVRDUDE. Ubuntu users can get the required software by running:

After you have installed the prerequisites, open a command prompt and try running these commands to make sure all the required utilities are available:

The environment is written in Java and based on Processing, avr-gcc, and other open-source software. You may want to check out more software for Mac, such as Arduino Create Agent, Mpide or visualino, which might be similar to Arduino.

If any of those commands fail, make sure the desired executable is installed on your computer and make sure that it is in a directory listed in your PATH environment variable.

Compiling an example program

Copy the following code to a file named “main.c”:

In the same folder, create a file named “Makefile” with the following contents:

Make sure that the PORT variable in the Makefile is the name of the device’s virtual serial port. In Windows, .GLOBALROOTDeviceUSBSER000 should work if the A-Star is the only USB device connected that is using the usbser.sys driver, but you can change it to be the actual name of the COM port (e.g. COM13).

In a command prompt, navigate to the directory with the Makefile and main.c. If you run the command make, the code should get compiled and produce a file named “main.hex”.

Programming

To program the A-Star device, you will need to get it into bootloader mode first. One way to do this is to reset the AVR twice within 750 ms. Most of the boards in our 32U4 family have a reset button that can be used to reset the board. On any of our 32U4 family of boards, a pushbutton can be connected between the GND and RST pins to serve as a reset button, or you can use a wire. Once the device is in bootloader mode, quickly run the command make program to program it. If you wait longer than 8 seconds, the A-Star bootloader will exit and the AVR will go back to running the user program.
