    yes i used ponyprog2000. i have this STK200. i setted the fusebits i locked 2 uP but i think i got it wright now. if you check out a function it means unprogrammed bit (0). so in the schematic if it is written 1 it means no tick wright? i triedthe other way around and i locked the uP iwill try the RS232 interface that you posted as soon as i get the MAX chip probably tomorrow

    Probe it this:

    4 pin (Xtal 2) - 5 pin (Xtal 1) = 16MHz quarz
    4 pin - GND = 22pF
    5 pin - GND = 22pF

    and read the chip.

    I can help you only in bascom.
    Screenshot's help you?

    i don't have truble with the programming. the uP is programmed without any errors. and the processor is running i just have trouble connecting it to the PC i thing there is something wrong with the chip that is in the schematic i'm reading strange voltages. i will try your interface.
    i know that the uP is working because the leds switch between the orange and the red.

    ok i got the max232 chip i assembled the circuit and connected it correctly to the tiny and still nothing. i don0t know why but i have a feeling that the comport doesnt send signals.
    and i don't really understand the Hypreterminal! So if everything is working when you press the connect icon what happens? because i dont get anything and if i try to type no letters show up on the screen and the crusor freezes for a second or two.
    i setted the com port and the baudrate and nothing. i bought some fresh TINY's and still no luck

    3. now connect 5V to chip

    then its all ok, send the chip to a terminal:

    Servo Controller.......


    Simple com port test: connect old com port pc mouse. When it work, com port is ok, or measure the port with scope (when you have it).

    What terminal program use you?

    Try it bray terminal (see attachments) the following properties:

    baud rate: 38400
    data bits: 8
    parity: none
    stop: 1
    handshaking: none

    connect the chip, connect the terminal, pover on (rs232 board...)

    when you see zig-zag characters, try change RECEIVE - hex - string mode (when run the program)

    Just an idea. Have you checked your MAX232? Is it working correctly?

    tak out the chip, and make short PIN 2 - PIN 3

    you make a "serial loop"
    when you send a command from terminal program, this is command com back now

    this give results on com port

    Try other test (rs232 board):

    take out the uC from the circuit - short PIN 2 - PIN 3

    when you send out the terminal program, this com back now
    this is a "serial loop", you can test with the com port

    mcan tnx for the link this helped allot but it still doesn't work.
    ok here is what i found out.
    the schematic is wrong but i corrected it (ok the connections but not the caps) the caps in your circuit are rate 1uf but on the web site they are 0.1uf anyway a made a loop-backand discoverd that the if i type in a character in the terminal the ascii code is transmitted and goes trough the MAX and back to the computer. so the terminal should repeat the character but it doesnt. so something else is wrong with the software but i can't figure-out what!
    any ideas?

    i switched the connection between the max and AVR and in your program i can see the data in the terminal that you attached ( 8D 45 5A 2A B5 0A 41 9D 90 5A 46 F9 BF 90 B3 43 DD B2 90 D8 EB F1 B2 CB D9 B5 79 48 A5 E2 E1 B5 B6 5C AA A8 D4 52 55 )
    but the hyper terminal doesn't repeat the letter what did i forget?

    In short:
    --------------------------
    You have a lancos stk200 programmer, with at2312-20PU.
    In ponyprog was set 16MHz outer crsystal.
    Apply 16MHz crystal (4 - 5), 2 x 22pF ( 4 - gnd, 5 - gnd).
    Use max232 circuit, what i was link.
    ...and not work.
    So far is correct?
    --------------------------

    Have you final board, to servo circuit?
    Try therewith connect to terminal.

    What results give the short in rs232 circuit?

    tady,
    If you can not have terminal software repeat the keys you pressed, when you shorted pins 11 and 12 of MAX232, then most probably you have an issue with your serial cable. Check each cable individually if there is a problem. If there is no problem with the cable, then check whether MAX232 pins are connected to PC com port correctly. Check from http://www.moxa.com/product/accessor...al_Pinouts.htm
