Create a new project in Uvision and then open the project properties

write fromelf --bin -o @L.bin !L in the "run user program after build" command.
This command generates the bin file from the elf file


Create a MBED_Flash.bat with the following content and place it in the project folder

Code:

:Batch file for copying to MBed
:argument 1: .bin output file

The atmega has a few different PWM modes, the frequency and duty ratio depend on the mode and values used, this is a description of the way to calculate them.

In fast PWM top=ICR1, the output PWM frequency=timer clock/(ICR1+1) and the duty=OCR1A(B)/ICR1
In fast PWM top=0h00ff, the output PWM frequency=timer clock/256 and the duty=OCR1A(B)/256
In fast PWM top=0h01ff, the output PWM frequency=timer clock/512 and the duty=OCR1A(B)/512
In fast PWM top=0h03ff, the

The following macro can be used to simplify the process of using the internal AVR EEPROM

Code:

#include <avr/eeprom.h>
// defines for eeprom access	
#define read_eeprom_byte(address) eeprom_read_byte ((const uint8_t*)address)
#define write_eeprom_byte(address,value) eeprom_write_byte ((uint8_t*)address,(uint8_t)value)
#define read_eeprom_word(address) eeprom_read_word ((const uint16_t*)address)
#define write_eeprom_word(address,value) eeprom_write_word
