To fix two bugs :) I make one (two patches) I don't know if is it possible to give the link on my page web
This is the read me If it is allowed and someone is interested I will write the link (it is free of course)
1) Sometimes when topwin is opening you can find the error message E ACCESS VIOLATION This is due to a cfg file created by topwin.
2) Topwin has a bug when it reads the data eeprom of microchip pic. Infact, topwin reads the data byte as opcode byte, for example
This is a opcode line :10 000000 3E29 1007 8207 3F34 4834 5234 5B34 6334 4E Topwin reads correctly the opcodes byte (4 units) (3e29 1007 etc)
But this is a dataeprom line :10 420000 0100 0200 0300 0400 0500 0600 0700 0800 8A
the correct way to read this data is: 01 02 03 04 05 06 07 08 (2 units)
Topwin reads in a wrong way 01 00 02 00 03 00 04 00 05 00 06 00 07 00 08 00 ---- How to resolve. a) Intall topwinen in default path (c:\top\topwinen\)
b) copy opentopwin.exe into topwinwn folder
c) create a opentopwin.exe link and copy it where you want (for ex. into start program folder) If you use this exe to open topwin you'd resolve the problem 1 (see below to explication) d) to resolve the problem 2 follow the same steps (point "c" it is not obligatory), copy Patc_ee_TW.exe into topwinen folder create a link and put it where you want.
e) using Patc_ee_TW.exe you can charge a hex file (for pic) and you will find another file hex (in the same folder of first file hex) called like this topwin_dd_mm_yy-hh_mm_ss_oldname.HEX
f) it is possible to open topwin using the special icon directly from Patc_ee_TW.exe
------ How they work
Both are vb6 programs
**opentopwin.exe**
is very simple
just few lines of code
>>>>>>>>>>>>>>>>>>>>>>>> Private Sub Form_Load() Dim Ritorno As Long On Error Resume Next Kill (App.Path & "\top2004.cfg") <<<< delete the file cfg
Ritorno = Shell("c:\top\topwinen\topwinen.exe", vbNormalFocus) <<<<< open topwinen If Ritorno = 0 Then MsgBox "Si è verificato un errore nell'apertura", vbCritical + vbOKOnly, "Errore!" Unload Me End Sub >>>>>>>>>>>>>>>>>>>>>>>>
** Patc_ee_TW.exe ** Read the hex file and copy the opcodes lines to another hex file. When it finds eeprom data save only the valid ones. Then using valid data it makes new hex line and find a new checksum byte. For ex.
EEpom data lines of original hex :02400E00F23F7F << config bit :10420000010002000300040005000600070008008A :1042100009000A000B000C000D000E000F0010003A :1042200011001200130014001500160017001800EA :1042300019001A001B001C001D001E001F0020009A :10424000AA00BB00CC00FF00FF00FF00FF00FF0042 :10425000FF00FF00FF00FF00FF00FF00FF00FF0066 :10426000FF00FF00FF00FF00FF00FF00FF00FF0056 :10427000FF00FF00FF00FF00FF00FF00FF00FF0046 :00000001FF << ending string
EEpom data lines of modify hex :02400E00F23F7F << config bit :104200000102030405060708090A0B0C0D0E0F10DB :104210001112131415161718191A1B1C1D1E1F20D9 :10422000AABBCCFFFFFFFFFFFFFFFFFFFFFFFFFFCF :10423000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFC9 :00000001FF << ending string
In this way because of topwin reads all bytes you will find the data eeprom bytes in correct location.
Tested up pic 16f84a but should works in several kinds of microchip's pics
