[TUT] [HARD] Parallel Port Programmer STK200 STK300, alikes
I think, if you build correctly the PPPD described in this thread there will be no problem. Read all the post carefully. If there's still a problem maybe you should check your AVR...

Logic Level Shifting from 0-5 V logic to -5 - 5 V logic
Hmm, thats a good one but I have to reverse my logical thinking, sometimes it's make me confuse.

Logic Level Shifting from 0-5 V logic to -5 - 5 V logic
Exactly, with MAX232 I don't need negative power supply. About MAX202, I never heard that before and I'm not sure about availibility of this component in my rural town. Beside I...

Logic Level Shifting from 0-5 V logic to -5 - 5 V logic
Thanks for all your replies. I've found the solution. I was using transistor (common emitter mode -> NPN Transistor) before but it wasn't work. After examining, its because the...

Logic Level Shifting from 0-5 V logic to -5 - 5 V logic
well, I think its gonna cost to much if i used 232 (so many capacitor there), because there are 10 data to be shifted. I need this shifting to drive the IGBT. My IGBT driver need...

[TUT] [C] Newbie's Guide to AVR Timers
Oh...maybe thats the problem, I use external crystal to clock the avr, so the timer is not clocked by system clock. Can't wait your tutorial then. Deni

[TUT] [C] Newbie's Guide to AVR Timers
Hi dean, nice tutorial. I have some basic question. First, is the timer running on the cpu clock, or based on the instruction? I try to simulate the code in AVR Studio and find...

Ok then, I'll build that PPPD. Ok, how about unplug the board but not the dongle? It is still dangerous?

[TUT] [HARD] Parallel Port Programmer STK200 STK300, alikes
Hi all, I want to share my problem about PPPD. About three years ago I built my own development board for AVR using ATMega8535 as core. Because I want to see ports condition so I...

I'm sorry if this is out of topic. it's too bad I don't read this thread before, cause now my parallel port is damaged. maybe its because I often plug and unplug my dongle when pc...
