Compiling and uploading code without an IDE

Using Arduino Microcontrollers
#1

Hi everyone

These are my first forays into embedded programming. Is it possible to cross-compile the code and push it into an Arduino UNO/Mega without using the ide. I know that it uses the avr-gcc cross-compiler, but how do i push the binaries/hex into the board.

Thanks Sam

How to make a standalone code uploader for arduino projects

avrdude

but how do i push the binaries/hex into the board.

The included AVRDUDE is the tool used to upload a hex file to an attached board.

Example usage:

avrdude -p atmega328p -D -Uflash:w:"main.hex" -v -v -F -c avrisp -P /dev/ttyACM0


<br>-p atmega328p<br>

 Upload to an Arduino Uno, which comes with an ATmega328p


<br>-D<br>

 “Disable auto erase for flash memory” - Actually I have no idea why I am using that option…
-Uflash:w:"main.hex" Upload main.hex to flash memory


<br>-v -v<br>

 Very verbose output


<br>-F<br>

 ignore invalid signatures - This is because due to the Arduino bootloader, the signature avrdude is expecting isn’t the right one


<br>-c avrisp<br>

 The type of the programmer - avrisp works for the Arduino
-P /dev/ttyACM0 Path to the programmer device. On Windows/Mac this will look different.

Suppose i have a custom board for an embedded application, using let's say LPC1768 or STM32F2 ARM cortex M3 series of processors. How would i port binary.hex code onto it? Which compilers would you recommend?

for the ARM there is an IDE that look similar to arduino ide and lets you program the ARM using a language close to the one used in arduino check here for more detaisl http://leaflabs.com/devices/maple/
