comparator problem...
still i dont get it why this doesnt work...
i using lm 339 as comparator ...
i already set voltage reference right between 2 condition of voltage input
but still the output is low(0V) with or without pullup resistor...
i already check the connection the circuit is right...
no output from avr ports
i'm using atmega 8535...
my minimum system avr is used to fine..but now its jams
in my minimum system avr, my microcontroller can programed but there is no voltage output...
to check the problem,i use simple program that only give all port high (255)
but still there is...

hi guys
i want to ask another dummy question...
common program but still i dont get it right...arrggghhh
my problem is no output in OC1A(PD5) dan OC1B(PD4)...
in my simulation in avr studio ...
TCNT1 is counting but no effect in PORTD but there is...
autotrax file format
hi guys
i'm using P*otel 99
i want to know what is autotrax format...
because if i open it with notepad...
i have something like this

hi guys..
i know this quite simple..but i still get trouble with this...
ok,first i have my old board(1 attiny 2313+ max232) which still work good (i assume... u can see why in my next explanation...) and my new board (1 attiny 2313+ max 232).
the problem are :
1. in my old board, the program...
mpcm txb8
answer nomor 3:
I am testing the MPCM mode(s) out just using a simple RS-232 between one attiny and one computer so i stil doesnt use max 491
answer nomor 4
if i using mpcm ...and mpcm bit is set then the slave cant communicate anything(i had test it...)
answer nomor 2
good...
Re: UART
i dont know that avr studio can do that...
but i know that code vision avr can uart and you dont have to use avr...
you can use terminal(computer icon) in code vision avr ...
but if you dont have the program ..you can use hyper terminal...
thats good enough:D
how set or reset a port attiny25 processor
the file is only 4kb...
vb code..
Private Sub Form_Load()
UartCom.CommPort = 1
UartCom.PortOpen = True
End Sub

Hi laktronics...
thx for your care...
yesterday i know where is my bug...
the bug is not in vb but my program in slave..(which i doesnt show to you..sorry)
for change the parity, i must have change TXB8...(in attiny2313):D:D
but will you help me again...
i have another problem...
here is the...
attiny to attiny communication
Hi guys..
thx for your care..
i have a project using computer as a master and 3 attiny2313 as slave..
they communicate with multi-processor communication mode(MPCM).
Right now, i just try one attiny as slave and a computer as master. Another two attiny still...
ya, its ASCII character...
M stand for i'm setting parity is mark....I use mark cause i'm using Multi-processor communication mode(MPCM) in AVR ... so i can talk to many address(uC) using RS-485.
In MPCM, first i must sending mark parity for give address of uC that i want to communicate...then...
hey guys...thx for your time ...
I have a project using another hardware device.The device communication with computer using serial port.
first,If i try to connect it with hyperterminal program from windows ... it doesn't have problem.(my hardware ok..)
but if try to connect to vb program the...
