How to connect Atmega88P ? It is working? (by Matthew)

Hello!

I'm Matthew and i'm from Poland :) I'm very happy of LDmicro. Unfortunately, in spite of a simple program (leds) my Atmega88 don't work. Therefore, if anyone could give wiring diagram button and LED, and say how I should set up LDmicro to ATMEGA88PA? (I have external quartz 8mhz). I think it should work setting for Atmega8, but it's not working.

Hi Matthew ..
Image for switch is wrong .. you use 1M ohm resistor for protection ?? it's too big ..
use less .. for example 1k or maximum 10k only ..

and here you can download latest complete source code (with special function) what support atmega88 too..

this code works fine :

#include <avr/io.h>
#include <util/delay.h>

int main(void)
{

DDRD = 0xFF;

DDRC = 0x00;
PORTC = 0xff;

for(;;)
{

PORTD = PINC;

}
}

THIS IS NOT WORKING:

LDmicroM=1
LDmicroS=1
MICRO=Atmel AVR ATmega88 28-PDIP
CYCLE=10000
CRYSTAL=1000000
BAUD=2400
COMPILED=C:\Users\Mjelec\Desktop\atmega88.hex

IO LIST
Xpd1 at 2
YB5 at 23
END

PROGRAM
RUNG
CONTACTS Xpd1 1
COIL YB5 0 0 0
END

i don't know what to do...:(

LDmicro.exe is only in directory "Release". I downloaded program in .C (with Eclipse):

#include <avr/io.h>
#include <util/delay.h>

int main(void)
{
DDRD = 0xFF;
DDRC = 0x00;
PORTC = 0xff;
for(;;)
{
PORTD = PINC;
}
}

It's working, LED is ON and when i push the button it goes to OFF.

I opened ldmicro.exe, wrote program like (screen)
NO REACTION :(

Dear Dzairo Sir,

Thanks for sharing your version of LDMICRO.

I liked and appreciate your version for AVRs.

Can you guide me step by step procedure to create hex file for atmega88 only simple blinking LED program.

I always use pic16f887 and never used Atmega mcu with LDMICRO.

For pic mcu LDMICRO create hex file which works very well but for Atmega little complected.

Please also tell me which best IDE for Atmega.

Thanks & regards,

Rajeev
