General information
1.1
Introduction
Thank you using the Velleman produkts. The VM134 (K8076 kit version) us a multifunctional and
instructional programmer, aimed at programming a selection of
. These FLASH controllers can be reprogrammed
many times, making them an appropriate tool for teaching a PIC programming language. Another
advantage of reprogrammable controllers is that software of a device where it is implemented can
easily be updated.
The VM134 PIC programmer is a ready-to-use version of our unassembled K8076 programmer.
Hence, the VM134 can also be referred as the K8076 in this manual and software.
There are 2 important stadiums in the use of this programmer. First, a programme code needs to
be written, usually in a graphic environment (IDE). For PICs that is MPLAB(™) by Microchip. This
. An
easier method is writing a programme in an ASCII word processing programm like e.g. Notepad,
installed on every Windows PC.
Information concerning the commands used in the assembler language for every controller type
can be found in data sheets on the Microchip website. An exemple programme is included on CD.

Connection cable
Connect your programmer to a free serial RS232 port of your PC. This serial port must be 100%
IBM compatible and 16550 UART compatible. This kit does not use the RS232 protocol but an
emulated I2C protocol via handshaking.
A UART, universal asynchronous receiver / transmitter executes the main tasks in the serial
communication of computers. The chip converts incoming parallel information into serial data
which can be sent through a communication line. A second UART will be used to receive the
information. The UART executes all necessary tasks like e.g. timing, parity control etc. needed for
the communication. The only extra chips needed are the line drivers converting the TLL-level
signals into line voltages and vice versa.
