mikroC vs BASCOM AVR

By WillFleischer

April 14, 2012

A few days ago I was going to try some programming in C using mikroC. So far I have been able to blink a LED... mikroC is primarily designed to support the circuit boards MikroElectronica makes and does very little for the Arduino (and they plan on keeping it like that). It is still a great (but expensive!) C, just not one for the Arduino.

Universal AVR ISP

By BiohazardRoboIn...

April 27, 2011

Hi to all, I'm quite new to AVR MCUs and I have the chips (ATmega32 16PU), but no programmer.

I'm obsessed by the word "universal", because I don't wanna buy a programmer every time I'm working with a different chip, so the question is: which is the really universal ISP for AVRs, possibly with USB connector?

Thx in advance ;-)

atmega32 INT2

By djhesit8

March 17, 2011

Hi...

I have an atmega 32... I want to use all of the 3 interrupts... I got problems with INT2...

I set it up as a falling edge and via a 10K resistor put the button to ground...

while(bit_is_set(PINB, PB2));

_delay_ms(5000);

//init interupt

GICR |= (1<<INT0) | (1<<INT1) | (<<INT2);

sei();

the problem is that after the while... when the interrupts are initialized... the pull-up drops out...

Hi!

Just found some interesting game where the avr is the "robot", connected to the PC and therefore the internet. There you can fight against other players robot and level up and so on. Or you can modify your actual hardware and increase your game-stats.

It's in alpha-state but i like the idea!

Last night I was building my next bot, Hammer, and I got to the point where I had all the electronics more or less completed and some mechanics done too. With some help from my dear friend hot glue I managed to build a shaky test platform. I hoped I could test Sharp IR distance sensor and motors. Maybe even do some simple navigation stuff. Here are a couple of pictures how Hammer looks like right now.

Hi all,

This may be stupid but I need to understand.

The problem:

We have two microcontrollers:

1 Arduino based on ATMega168

1 ATTiny2313.

Link three pins of your choice between them, for example

Arduino Tiny

9 - PB5

10 PB7

11 PD3

We want the tiny to respond to low/high states on the Arduino pins.

Bricked! ATTINY2313 Repair with HV Rescue Shield

By John_NY

February 18, 2010

Summary

This blog post contains my build of a "HV Rescue Shield" by MightyOhm. The High-Voltage Rescue Shield is a high-voltage programming shield that fits on an Arduino. The Rescue Shield works on 28-pin ATMEGA ICs and on 20-pin ATTINY2313 ICs. My use/instructions for now only concern resetting the LFUSE (clock fuse) so that the IC can be used with a 16MHz crystal.

Introduction

I bricked my $3 µC IC on my first attempt at programming. Recently I found some DIY AVR HV programmers that could be made from stuff in my lab.
