  1. Oh,It seems you have built a STC ISP software.
    here is my software:http://www.rwzy.co.cc/archives/1196
    I have test 1 week to test it.such as options….checksum…..
    and test options bits….
    now i want to decode STC15 series MCU protocol.

  2. —QUOTE——
    Since the baudrate switching involved is still somewhat a mystery right now, it ONLY works with a 12 Mhz quartz. Well, not a complete mystery, but it’s hardcoded right now. Sorry.
    Implemented in trunk. 3 bytes are still unknown, so not all baudrate/frequency combinations work

    Setting the MCU options is NOT supported yet. You’ll still need the stock ISP software to do so.
    The last ‘encrypt’ step is omitted. I’ve got no clue what it does (lock the flash?), but it works without it.
    ——QUOTE————-
    发送数据 8F xx yy zz aa dd ee

    xx= ab00 0000
    a=T1x12
    b=Double baudrate

    yy is Reload value for BRT

    zz is Setting check sum.(zz=~xx)

    aa is Reload check sum ,aa=2 * (0×100 -yy)

    dd is Delay value.to change MCU ;’s delay time

    ee is IAP timer.In fact,use 0×83.

  3. By the way.
    MCU model number(magic number) format:
    I write a program on BASIC to parse the model:
    PUBLIC FUNCTION GetMCUType(Model AS Byte, Size AS Byte) AS String
    DIM tempStr AS String
    DIM v AS Byte
    DIM iapF AS Boolean
    iapF = FALSE
    IF BTst(Size, 0) THEN
    tempStr = “IAP”
    iapF = TRUE
    ELSE
    tempStr = “STC”
    END IF
    SELECT CASE (Model)
    CASE &HD1 ’0xD1
    tempStr = tempStr & “12″
    END SELECT

    IF BTst(Size, 7) THEN
    tempStr = tempStr & “LE5A”
    ELSE
    tempStr = tempStr & “C5A”
    END IF
    v = Lsr(&H1E AND Size, 1)
    IF iapF THEN
    tempStr = tempStr & “62″
    ELSE
    IF V > 9 THEN
    tempStr = tempStr & Str(v * 4)
    ELSE
    tempStr = tempStr & “0″ & Str(v * 4)
    END IF
    END IF
    IF BTst(Size, 6) AND BTst(Size, 5) THEN
    tempStr = tempStr & “S2″ ‘S2
    ELSE IF BTst(Size, 6) = TRUE AND BTst(Size, 5) = FALSE THEN
    tempStr = tempStr & “AD” ‘AD
    ELSE IF BTst(Size, 6) = FALSE AND BTst(Size, 5) = FALSE THEN
    tempStr = tempStr & “X” ‘X
    ELSE
    tempStr = tempStr & “CCP” ‘CCP
    END IF
    RETURN tempStr
    END

  4. oh by the way.STC hasn’t encode…
    because ISP protocol is DISABLE to read.

  5. I decode the STC protocol is using Virtual Box and USB to RS232 bridge PL-2303.and a Saleae Logic Analyzer

  6. typical payload: 8F C0F3 3F1A 2883

    8F – packet type?
    C0 – PCON value, sets SMOD bits.
    F3 – Sets the actual new baudrate
    3F – checksum of PCON and AUXR value(=~0xC0)
    28 – Switch to new baudrate ‘s delay time
    83 – IAP Timer

    By the way,0×68/0x6A,0×00 it is means IDENT.Length is only 1 byte long.
    I think STC frame format is :
    |46 B9|68/6A 00|length|command|checksum|0×16

  7. I want to tell you I have been to build kSTC-ISP on GUI.using GAMBAS.

    > I want to tell you I have been to build kSTC-ISP on GUI.using GAMBAS.
    My point was avoiding any GUI, and doing a commandline tool to use from Makefiles.

    Thanks for the info, just don’t post such long messages in comments, some pastebin or email would do. It’s pain to read otherwise.
    I have figured out most of the baudswitching stuff and it’s pretty reliable right now. Thanks for the tip regarding the checksumming of the settings (although, it looks like mcu doesn’t care much about it, I’ll implement it some time soon). EEPROM writing will be in trunk some time soon.
    I don’t think parsing the magic bytes like that is a good idea, since:
    a). I got a good mcudb right here right now: https://github.com/nekromant/stcdude/tree/master/src/lua/mcudb obtained from original ISP tool
    b). The point of mcudb is to merge it with info from Keil CDB file, which was done up there.

  10. EEPROM ‘s address is after FLASH ‘s address.
    so you can only use a BINARY FILE to write the STC EEPROM.

  11. By the way,STC15 series and STC89 series writing Protocol is not the same .
    such as Parity…checksum….

  13. By the way…. I want to say.STC MCU is a shit…..
    Please open the AD-manual,and search OP table.
    you can find 1T complete OP is only just 12.and it include NOP!
    And for wider working voltage……I think it is not called wider.
    ISP speed is too slow.Handshake is waste a lot of time.
    And IAP module has been malfunction..such as Earse all Flash memory.
    I think some chip.Such as AVR-compat chip.like LGT8F08A,it is cheap than STC.
    and can get higher performance than STC.
    I ‘m reverse engineering LGT SPI ISP protocol now.It writing very fast.could use 10S write all of the FLASH(SPI Speed 1.4Mbps).Earse just 20mS.it just like ATmega168.I think it is a great chip.
    Here is LGT ‘s website.http://www.mcugreen.com
