1  Forum 2005-2010 (read only) / Troubleshooting / ATMEGA168 on: November 11, 2006, 09:42:37 am
I plan to build an ARDUINO serial board but using an ATMEGA168 in place of the AT MEGA8.

Where is the firmware ( HEX file ) to use for the AT MEGA 168 ?


             Best regards

It will be nice to use the interrupt to start a subroutine.

Like :  ON_INT myintfunction()


How can we use interrupts ?

I am using a L293D and PWM to set a motor speed.
But the frequency is too high.

How can I modify the freqency of the PWM ?
I need somethink like a few Khz ( 2 Khz for exemple )

Salut,

Voici mes recommendations :

0.1 µF ceramique à l'entrée et à la sortie ( indispensable ).
100 µF electrochimique à l'entrée.
47 µF electrochimique à la sortie.


             Salutations,

                     Georges

In the schematic version 1 and 2.
C8 is to be inverse.

A suggestion for Hardware and Software.

Add an I2C connecteur on the board ( 2 wires ) and add a library to read/write I2C peripherical
 like eeprom / Real Time Clock or Devantech Compass...


                 Best regards
