Need help Propeller clock with ATMega16

[Coita Petru-Daniel]

I want to build a propeller clock using ATMega 16 . Does anyone have a schematic file for this king of project?

I want also to use 3 74hc59581 latches for my Rgb Leds and i also need some help with the code. If anybody has done this , please share

yes

im working on the same project

first i made it with 8051 later i developed it with atmega16L

 

currently im working to stebilize the display using a IR slot sensor and interrupts of atmega16,

 

if you want to make a simple one

you need to work on delay calculations as per your motor.use the delay functions given in util folder in winavr

#define F_CPU 16000000UL

// as per your working frequency

#include<util/delay.h>

 

the functions are

_delay_ms(1000);//1000milliseconds delay

_delay_us(1000);1000micro seconds delay

Thank you for the advice . I’ve read your blog and it hink you did a great job . 

I also read the comments , you offered the code in C . Could you please send it to me on my email [email protected]?

Have you used the IR emitter to activate the main interuption ( when the propeller completes a full rotation)?

Thank you again

if we use IR led and photodiode the switching will not be accurate. and it wont work properly at high speeds
