I would like to make available using the MAX7219 example with 7 segments
button and sound or watch would be very useful to learn
tried to put together the sound matriz8x8 but is catching all need some more examples of a conjugate function have a pic Easy v7, thank you!

*/
#define IMG_SIZE 20
#include "8X8 FONT.h"
#include "LED_Driver.h"

// Serial 7-seg Display connections
sbit sfr Chip_Select1 at RE0_bit;
sbit sfr Chip_Select_Direction1 at TRISE0_bit;

sbit sfr Chip_Select2 at RA5_bit;
sbit sfr Chip_Select_Direction2 at TRISA5_bit;
// Serial 7-seg Display connections

char i;
const unsigned char intro[] = " mikroElektronika 8x8Rclick"; // Text to display
void main() {
SPI1_Init(); // Initialize SPI module
max7219_init(1); // initialize max7219
max7219_init(2); // initialize max7219

slide_text_double(intro); // Text slide animation

while(1){
for(i = 0 ; i < IMG_SIZE ; i++){ // Play graphical sequence forward
display_image_const(img1[i], 1);
display_image_const(img2[i], 2);
Delay_ms(120);
}
Delay_ms(600);
for(i = IMG_SIZE-1 ; i > 0 ; i--){ // Play graphical sequence backward
display_image_const(img1[IMG_SIZE-1-i], 1); // Reverse and play forward 8x8 R click in first mikroBUS socket
display_image_const(img2[i] ,2);
Delay_ms(120);
}
}
}

THIS TYPE

Hello !, Cool would like to see a change
message by the computer, a sound beep type like this:

void Melody() { // Plays the melody "Yellow house"
Tone1(); Tone2(); Tone3(); Tone3();
Tone1(); Tone2(); Tone3(); Tone3();
Tone1(); Tone2(); Tone3();
Tone1(); Tone2(); Tone3(); Tone3();
Tone1(); Tone2(); Tone3();
Tone3(); Tone3(); Tone2(); Tone2(); Tone1();
}

or type this:

UART1_Init(4800); // initialize UART1 module
Delay_ms(100);

while (1) {
if (UART_Data_Ready() == 1) { // if data is received
UART_Read_Text(output, "OK", 10); // reads text until 'OK' is found
UART_Write_Text(output); // sends back text
}
}

thank you!

50 hz pwm atmega 16

i want to simple 50hz code for atmega 16
without library alredy i have code but it not wirking

void main()
{
//Configure TIMER1
TCCR1A|=(1<<COM1A1)|(1<<COM1B1)|(1<<WGM11); //NON Inverted PWM
TCCR1B|=(1<<WGM13)|(1<<WGM12)|(1<<CS11)|(1<<CS10); //PRESCALER=64 MODE 14(FAST PWM)

ICR1=4999; //fPWM=50Hz (Period = 20ms Standard).

DDRD|=(1<<PD4)|(1<<PD5); //PWM Pins as Out

while(1)
{

OCR1A=97; //0 degree
Wait();

}
