wa hari sabtu adalah hari yang menyenangkan. Hari ini aku mencoba membuat aplikasi proyek pertama menggunakan winavr. Biasanya aku memprogram menggunakan codevision. Iseng-iseng beberapa bulan yang lalu aku menemukan situs compiler avr menggunakan bahasa C yang bisa di download dan dikembangkan sourcenya. Percobaan pertamaku adalah membuat lampu berkedip yang sudah nempel diport D. Untuk itu port D harus aku inisialisai menggunakan mode output dengan perintah
DDRD=0xFF;
langkah berikutnya adalah membuat lampu berkedip dengan membuat port D bernilai 1 dan bernilai 0 secara bergiliran. Karena itu aku perlu delay. Wa bagian ini memang bikin pening kepala karena yang kuharapkan tidak berjalan dengan mulus.Cari-cari resource delay akhirnya dapat di folder c:\WinAVR\avr\include\util\. O iya resource input-output ada di c:\WinAVR\avr\include\avr pustaka tersebut di masukkan dalam program dengan perintah
#include <util/delay.h>
#include <avr/io.h>
pustaka delay adalah pustaka delay loop, sehingga untuk memastikan bahwa hitungan timing bisa tepat perlu diperintahkan agar compiler mengerti kristal yang digunakan dengan perintah
#define F_CPU 4000000UL
definisi diatas menerangkan bahwa kristal yang digunakan sebesar 4Mhz. Definisi tersebut boleh juga di gantikan oleh parameter waktu saat dilakukan proses kompile.
Bagian yang lain adalah memastikan lampu berkedip dengan menggunakan fungsi _delay_ms() yang terdapat pada library util/delay. Yang di inginkan adalah delay sekitar 1 detik dengan perintah _delay_ms(1000). Ketika di gunakan delay diubah dari 500ms sampai 10 detik ternyata tidak ada perbedaan yang cukup mencolok. Wa sepertinya adalah masalah. Lihat bolak-balik, kompile bolak balik tetap aja tidak ada bedanya. Setelah buka dokumen pada file c:\WinAVR\doc\avr-libc\avr-libc-user-manual/group__util__delay.html ternyata delay maksimal adalah sekitar 262.14 ms .
O.. ini nich masalahnya
Yap akhirnya program diubah sedikit dengan menambah fungsi delay_dt yang didalamnya mengulang fungsi delay_ms(200) sebanyak 5 kali sehingga tercapai satu detik. program sebagai berikut.
#define F_CPU 4000000UL
#include <util/delay.h>
#include <avr/io.h>
void delay_dt (unsigned int param)
{
char i,j;
for (j=0;j<=param;j++)
{
for (i=0;i<=5;i++)
{
_delay_ms(200);
}
}
}int main (void)
{
DDRD=0xFF;
while(1)
{PORTD=0;
delay_dt(1);
PORTD=0xF0;delay_dt(1) ;
}
}
Untuk proses compile program digunakan bantuan program scripting make yang menjalankannya dengan menggunakan perintah
make all: digunakan untuk mengkompile program.
make clean : digunakan untuk menghapus file hasil kompile
make program : mendownload program lewat programmer avrdude
Langkah yang dilakukan buat file baru dan sisipkan script dibawah inii ke file baru tersebut dan simpan dengan nama nama Makefile. Kemudian jalankan perintah make clean, make all dan make program. Oiya untuk jenis mikrokontroller avr dan programmer yang berbeda terlebih dahulu menyunting file Makefile. beberapa item yang aku edit adalah :
MCU = atmega8535, option ini berhubungan dengan jenis uc yang digunakan
TARGET = firstproject, option ini adalah nama file hex yang di upload ke uc
AVRDUDE_PROGRAMMER = avr911, adalah jenis programmer yang digunakan
AVRDUDE_PORT = com1 # programmer connected to serial device
sedang bagian yang saya tambahkan adalah
AVRDUDE_BAUDRATE = 115200
AVRDUDE_FLAGS = -p $(MCU) -P $(AVRDUDE_PORT) -c $(AVRDUDE_PROGRAMMER) -b $(AVRDUDE_BAUDRATE)
parameter baud rate saya tambahkan karena programmer avr911 tidak bisa jalan kecuali baudrate diatur sebesar 115200 Bps
Bagian terpenting
tambahkan pada avrdude.conf parameter dibawah ini agar device tersebut bisa diprogram menggunakan avrdude versi 5
