The higher-level functions are on the left side. While most of the options are available in the preferences menu, the application places them, and many others, in one location for easy customization. Online search: Easily accessible with a few clicks through the menu bar, the online search works flawlessly. Overall, the application performs well despite being a Windows port.

This is the usual operation sequence in interactive mode for command-line mode, see another chapter : Start the programmer and, if required, connect a 13V-power supply Select the device type if necessary because different PICs require different programming algorithms Load a HEX-file with "File.. The software will always show the success or errors of all actions.

After programming, reading, or successfully verifying the PIC device, the programmer or ICSP-adapter can be completely disconnected from the target for test code runs. The "disconnect control signal" is D7 on the LPT port, explained in the appendix. Batch Programming "loop" To program a whole bunch of devices with the same data, load a hex file once, then select "Tools" Once in this mode, the following steps are repeated over and over until you stop the batch mode by pressing ESCAPE or via menu.

The program will ask you to insert the next device to be programmed, or connect the ICSP in-circuit serial programming adapter to the target. When ready, press the "Enter" key on the PC keyboard or if exists a pushbutton on your programming adapter. Programming will start then, taking a few seconds.

WinPic will go back to step one. Note: A pushbutton on the programmer and the two LEDs are only available on certain programming interfaces for the parallel port. Command Line Arguments You may call WinPic from a batch file, or an integrated development environment to do an automated job without any user intervention. For example, you can tell WinPic to load a program from a hexfile, write it into the target device, and terminate itself afterwards. If the file cannot be loaded, the evaluation of the command line is cancelled immediately; you can try to load the file "manually" then.

Compares the contents of the device with the specified HEX file. Should be the last argument, if you want to terminate WinPic after the job is done automatically. Without this command, you must close WinPic manually, even when running in command-line mode. This can rescue a chip, because it allows you to terminate the erase-programming operation if you have started the wrong batchfile by mistake, etc.

No space characters are allowed in here! The parameter XXXX is as a four-digit hexadecimal value. The main menu will be enabled anyway. Selecting certain menu items also cancels evaluating the command line. HEX, programs it into the connected device, and terminates WinPic "quit". Terminates automatically. Interface settings The interface type must be set once after program installation, then forget about it - because WinPicPr saves the interface type along with other settings in an INI file.

You can select the interface type from a list on the "Interface" sheet. Depending on the interface type, you may also select COM The default interface type is the "COM84" interface which is connected to the serial port.

If you have a simple programmer for the parallel port which is not listed, you can add support for your own interface by adding a few lines to the SETTINGS. INI files as described in the appendix. Since November , it does not need such a port driver for the serial port. The programmer does a crude "interface test" at program start to check if the interface is installed. If an error is reported, either the interface is not connected properly, or power turned off, or wrong port selected.

A crude interface test can be performed by clicking the "Initialize! The result of the interface test can be viewed on the Messages sheet the last message is displayed in the status line, clicking it will switch to the Message sheet with an error history. So it is your duty to set the correct programming- and supply voltage for your PIC. Thus, in Usually requires an extra power supply because the voltages from the serial port are often not sufficient to switch the PIC into programming mode.

Caution: recent reports seem to indicate a problem with the Tait interfaces, so beware..
