Jaakko Hyvätti Picprog 1.7 documentation
See the hardware section. This device is connected to a usual serial port of your PC, and is thesame device as used with many DOS PIC burning programs.
This program is written in C++, so you need a C++ compiler to compile it. This you should already have installed on your Linux system or Windows/Cygwin system.
Linux kernel version 2.0.32 or 2.1.45 or later.
PIC16 and PIC18 microcontroller programmer for Linux and Windows/Cygwin.
This programmer needs some functionality in Linux serial driver that as of kernel versions 2.0.32and 2.1.45 is available in standard kernels. The programmer uses TIOCSBRK and TIOCCBRK ioctl to control the state of TxD serial port output accurately. These ioctl’s are standard on BSDflavor unixes, like SunOS 4, but they still are unimplemented on many serial drivers in Linux kernel. Only the standard serial port is known to work by me.
(For Windows installations only) Earlier Cygwin versions do not contain the necessary TIOCSBRK and TIOCCBRK ioctl functionality.
Your assembler, or C compiler, or whatever, should produce either Intel IHX32, IHX16, or IHX8M format hex files. For assembler on Linux I recommend GNU PIC Utilities gpasm.

Use a serial port programmer device with the following pinouts: 11. Other available programmers12. Available languages PICmicro microcontrollers, or MCUs, are fine chips that are especially easy to program with a simple A very good programmer like this is for example PIC-Programmer 2 designed by Jens Madsen. I have device attached to a parallel or serial port. Because of the EEPROM or Flash memory, they are also heard that other programmers work also, for example TE20 and Olimex PG2C have been tested with easy and fast to erase and reprogram without need for UV equipment. This makes them very popular The description below is based on old version of JDM hardware. There is a new version of the PCB At the moment this is the second implementation of a PIC programmer for Linux that works with the available on Jens Madsen site. It supports more chips without jumper wires: PIC-Programmer 2. Please very simple and cheap serial port programmers. The first one I know was made by Ralph Metzler in use that one instead. Note however that his PCB does not support for example PIC16F628A that need 1996. My programmer was originally designed for PIC16C84 and PIC16F84 chips back in 1997, and to have pin 10, RB4/PGM grounded. Please modify the PCB to ground this pin if your chip has PGM since then I have implemented other chips without access to most of them. I have tested PIC16F628, PIC16F676, PIC12F675, PIC16F88, PIC16F876A, PIC16F76, PIC18F1320 and PIC18F458. Othershave used many other models.
I made a minor modification to the jdm84v23 schema and pcb mask, because I thought D4 was stressedon positive clock pulses - it short circuits the rs-232 RTS pin to GND. I added a 10k resistor between 1. Background reading
D4 and D3. But it also is not absolutely required, as the clock pulses are short and rs-232 is protectedfor short circuits anyway. Now I have noticed that this resistor makes the programmer less reliable,especially with later PIC chips, like PIC16F76 and PIC18 family. If you have built the hardware I You really should take a look at the Microchip www-pages and read the device datasheets and previously suggested, and it does not work, please short circuit that resistor or build the new PCB from Maybe the best source for PIC information is the home page of PICLIST discussion group. Also To support for example PIC16F628 and PIC16F88, which have a low voltage programming mode, the historically a good collection of links and software for PIC was in David Tait’s PIC links page and in circuit was again modified to ground the RB3 pin 9 and the RB4 pin 10. This prevents the chip from GNUPIC pages. I have also documented here the software I took a look at back in 1997. I have focused entering the low voltage programming mode. To support for example PIC12F675, PIC16F630, and into Linux support, so I have never used any DOS software mentioned.
PIC16F676, pin 1 was connected to Vdd. Other jumpers need to be installed as described below.
Jaakko Hyvätti Picprog 1.7 documentation http://hyvatti.iki.fi/~jaakko/pic/picprog.html Jaakko Hyvätti Picprog 1.7 documentation http://hyvatti.iki.fi/~jaakko/pic/picprog.html above pcb. You need to connect pin 16 on the socket to clock (same as pin 12), pin 17 to data (same aspins 11 and 13), and pin 18 on the socket to Vss (same as pins 5-10). Note that pin 1 is alreadyconnected to Vdd in the above PCB mask. If this connection is missing on your older PCB, connect pin1 to pin 14 with a wire.
Always check the correct pinouts for your chip from the datasheets also! 4. Installation
There are binary packages available that have been prepared by helpful users and operating systemvendors. I know of the following, but cannot offer any support for them. They might be for olderversions, but even if they are, check for the 10. Changes section below if you really need a laterversion. Some new versions of Picprog only fix small specific bug, which may not affect you at all.
FreeBSD includes Picprog port.
Gentoo has Picprog as a package.
Jan Wagemakers made a Debian package.
Linux i386 rpm compiled on Red Hat 9 by Maarten Blomme To install from source, download the picprog-1.7.tar.gz package, if you do not already have it.
Check your system against the requirements mentioned above. Untar the archive and change to the source file directory. You should only have to type: and the program should compile without errors or warnings. If it does not, please check that yourcompiler, c and c++ libraries and utilities like make are of a reasonably recent, bugfree and compatibleversion.
After compilation you can, as a root user, just type: to install the program and manual page to /usr/local. Or just copy the files picprog and picprog.1 manually.
The Linux emulator for Windows, Cygwin, allows Picprog to be compiled on Windows plattforms.
To install Cygwin, go to www.cygwin.com and follow the instructions there. In short, download To support for example PIC16F876A and 16F76, which have different pinouts for programming setup.exe and run it. You need to install at least the Developer packages Gcc C compiler, Gcc C++ signals, you need an adapter that connects to the external connector of the above programmer.
compiler, Make, and Binutils in addition to the default install.
Alternatively you could redesign the pcb layout, but maybe it is easier to just solder the adaptor. Solderthe pins like this: To install Picprog on Cygwin, follow the above instructions for Linux compilation from source.
Windows 2000 installations that I have tried work fine. Windows 98 installations worked sometimes, connector 3 -- data -- 28 (RB7) socket 5 -- Vss -- 8,19,24 and I suppose the timing routines of Picprog do not work well on Windows 98, they even lock the computer sometimes. I suggest using Windows 2000 or later.
To support for example PIC12F675, PIC16F630 and PIC16F676, which have different pinouts for programming signals but do not conflict with PIC16C84 pins, you can solder jumper wires on the Jaakko Hyvätti Picprog 1.7 documentation http://hyvatti.iki.fi/~jaakko/pic/picprog.html Jaakko Hyvätti Picprog 1.7 documentation http://hyvatti.iki.fi/~jaakko/pic/picprog.html To get information about the usage of the program, just type the program name.

Before interfacing with the PIC chip, Picprog calibrates its delay loops by checking the clock speed ofthe CPU and whether the CPU supports the TSC feature. On Linux, /proc/cpuinfo is read. On Windows/Cygwin, /proc/cpuinfo is read and CPU clock frequency is estimated. Therefore the clock class picport: manipulates the serial port hardware. With this class you can execute programming frequency displayed on Windows is not necessarily exactly the true clock frequency.
commands like read a word, program a word, increment address etc. Look at picport.h for details.

10. Changes
1. Insert the PIC chip into the socket in the programmer, or connect the in-circuit programming 2. Connect the programmer device to a serial port.
This document has not changed much since it was first released with the 1.0 programmer. The changes include some information about new software and more accurate links to PIC information. New optionsto select type of device other than pic18c84 are also present.
picprog --output ofile.hex --pic /dev/ttyS1 With help from Taneli Kalvas changed the schemantics diagram and pcb mask to ground the RB4 pin,selecting high voltage programming on for example pic16f628. --output-hexfile path, -o path Implemented preservation of OSCCAL and other calibration data. Specifies the output hex file. The file will be written in IHX16 format, unless otherwise specified Added automatic detection of devices based on location 0x2006. by the --ihx8m or --ihx32 options. For PIC18 family devices, file will be written in IHX32 format.
Merged Bart Goossens’s changes to implement PIC16F73. I hope it works.
When reading the PIC device, do not consider the all-ones memory locations to be programmed, and skip them in the hex file output. For 14 bit devices, this skips the program memory locations Autodetect more chips. Fix programming of chips with OSCCAL. Fix erasing some chips - erasing and that have hex value 0x3FFF, and for PIC18 family devices, this skips byte values 0xFF. In data resetting code protection is now performed the hard way: all methods are tried regardless of chip type.
memory locations that have hex value 0xFF are skipped.
--erase now works also without --input-hexfile flag.
Select the output hex file format to be either ihx16 or ihx8m, respectively. The default is ihx32 for PIC18 family devices and ihx16 for others.
Add option --force-calibration to program OSCCAL and BG bits. Implement programming algorithms for --pic-serial-port device , -p device 16f87/16f88 and 16f87Xa. Revise some timings on programmer reset to avoid operating voltage to dip.
The device name of the serial port the programmer is connected to. Default is /dev/ttyS0.
More verbose output on how many locations actually were burned.
