- what it is
- ----------
- This project is an built it yourself Eprom Programmer.The development
- was aimed at the Satellite amateur,but it can be used for other
- purposes of course.
- This is not a fast production programmer ,but it can program many
- different types.
- The double sided PCB is designed so that it can be home made relatively easy.
- The software is (hopefully) user friendly enough to be able to work
- with it fast and easy.
- You can also switch to the 'Henk Schaer' Compatible mode for advanced
- PIC 16C84 programming.
-
- types
- -----
- the programmer does the following types:
- parallel eproms
- 27C64 .. 27C040/4001
- 28C65 .. 28C040
- 28F64 .. 28F040
- 29F64 .. 29F040 (next update)
-
- serial eproms
- 24C02 .. 24C65
-
- PIC 16C84 and 16F84 microcontroller
- PIC 12C508 and 12C509
-
- not all types have been tested and some have yet to be added to the
- software.the most used types do work.
- new types will added in the future with coming software updates.
- to program the UV and Flash 51 family controllers there will be
- (built it yourself)adaptors soon.
-
- hardware
- --------
- the hardware is in fact only an extented interface for the printerport.
- all programming 'intelligence' is in the software.
- the working in short is as follows:
- Eprom addresses are send serially (max 18 bits) to the hardware and
- there converted to parallel with shiftregisters.reading is done with parallel
- to serial conversion.the data to be programmed is send through the printerport
- 8-bit databus.this system was chosen to keep the PCB as simple as possible.
- the use of serial communication through the printerport turned out to be
- reasonable fast and absolutely reliable.
- the serial Eproms and the 16C84 are programmed through a seperate I2C bus.
- Only cheap standard parts are used.
- The different types are selected with DIPswitches,these are not suitable
- of course for intensive day to day use.this programmer is not meant for
- that purpose.
-
- assembling
- ----------
- building this project is not difficult and can be done by everybody with
- some basic electronics skills.
- the IC's can be welded on the board directly or you can use precision
- DIL sockets(these can be welded on the component side).
- The programming sockets should precision types also of course,you can
- insert ZIF sockets (Textool or Aries) in these.
- The board can be used up to the XXX040 types Eproms.if XXX020 is enough for
- you,you can use a 10 pole DIPswitch.(bridge nr. 11)
-
- 2732
- ----
- to program the 2732 type Eprom ,you have to make a small modification.
- see 2732mod.pcx
-
- power supply
- ------------
- power supply can be both AC or DC: 15..20 V 100 mA.this is not critical.
- the voltage on C1 should be always above 15 volts.
-
- board
- -----
- you can make the double sided PCB yourself,if you have some experience
- with this.The dimensions are 160x100 mm (EuroCard).
- If you don't want to make the board yourself it can be ordered for 40.-
- guilders.P&P depends on destination.
- With this release(0.80 2/6/98) there are some changes:
- The reedrelay has been replace by a transistor switch
- the 25Cxx socket is now adapted for the PIC 12C508 and 509.
- the Henk Schaer mode switch has been removed.
-
- use
- ---
- this version works with Windows(95).you have to make a shortcut with
- idle_sensitivity setting at LOW(properties), otherwise reading will become
- extremely slow in some cases.
- most of the program should obvious(I hope).
- UV Eproms should be programmed with the 'express'(Quick pulse) mode.
- Some older Eproms may need the slow 'Normal' setting.you can experiment
- with different Burntime settings for this mode.
- alway first select the type and set the DIPswitches,then load the HEX or
- BIN file.Hex files can be off the HEX8M Intel or Motorola S1/3 type.
- Hex files should have the *.hex extension, Bin files the *.bin extension.
- these should also be in the same directory as the programmer.
- you can save a chipdump as a Hex or Bin file.the *.hex or *.bin extension
- will be added automatically.
- with "fasterase" flasheproms are erased much faster,if this doesn't
- work correctly set this option to "off".
-
- assembled and tested
- --------------------
- the programmer can also be ordered completely assembled and tested.
- inform for prices and P&P costs.
