Programming the Board
Overview
The following chapters show you in detail how to program the different aspects of the board. For every topic there’s a small example. For
the examples we focussed on Visual C++. However as shown in the last chapter the differences in programming the board under different
programming languages are marginal. This manual describes the programming of the whole hardware family. Some of the topics are similar
for all board versions. But some differ a little bit from type to type. Please check the given tables for these topics and examine carefully which
settings are valid for your special kind of board.

Register tables
The programming of the boards is totally software register based. All software registers are described in the following form:
If no constants are given below the register table, the dedicated register is used as a switch. All such registers
are activated if written with a “1“ and deactivated if written with a “0“.
are activated if written with a “1“ and deactivated if written with a “0“.
Programming examples
In this manual a lot of programming examples are used to give you an impression on how the actual mentioned registers can be set within
your own program. All of the examples are located in a seperated colored box to indicate the example and to make it easier to differ it from
the describing text.
your own program. All of the examples are located in a seperated colored box to indicate the example and to make it easier to differ it from

All of the examples mentioned throughout the manual are basically written using the Visual C++ compiler for Windows. If you use Linux there
are some changes in the funtion’s parameter lists as mentioned in the relating software chapter.

To keep the examples as compatible as possible for users of both operational systems (Windows and Linux) all the functions that
contain either a board number (Windows) or a handle (Linux) use the common parameter name ’hDrv’. Windows users simply have
to set the parameter to the according board number (as the example below is showing), while Linux users can easily use the handle

to set the parameter to the according board number (as the example below is showing), while Linux users can easily use the handle
that is given back for the according board by the initialization function.
Error handling
If one action caused an error in the driver this error and the register and value where it occurs will be saved.
The driver is then locked until the error is read out using the SPC_LASTERRORCODE function. All other functions
will lead to the same errorcode unless the error is cleared by reading SPC_LASTERRORCODE.

SPC_COMMAND

r/w
Command register of the board.
SPC_START
10
Starts the board with the current register settings.
SPC_STOP
20
Stops the board manually.
// Windows users must set hDrv to the according board number before.
// Assuming that there is only one Spectrum board installed you’ll
