About my MiniPOV, need suggestion pls

Post by Anjang »

I've made my Mini POV v3.
all route've been checked twice, all connected.

But when it turn on, LED 1 and 5 dimmed. Is there OK?
And I couldn't connect to serial port.
Any suggestion? what should I do?

Is there any differences between ATtiny2313V-10PU and ATtiny2313V-20PU?

I really need help. Any suggestion would be appreciated.

Rgds,

Anjang

bad solder joints or wrong resistors. do the other six leds come fully on?

bad solder joints or wrong resistors. diode orientation. host configuration.

not as far as the minipov3 is concerned.

it sounds as though you may have scratch built your minipov. if the chip is not yet programmed and leds 1 and 5 are coming on dimly, there is something seriously wrong with your wiring.

No. the other six is off, btw, i used 47 Ohm resistors for the LED. Not 100 Ohm.

I've double check all connection. And i'll do it again.

Thanks :D 'cos i used 20PU for the MiniPOV not 10PU.

That's exactly what i want to find out.

Any other suggestion :?:
