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:

The name of the software regi- ster as found in the regs.h file. Could directly be used by C and C++ compiler

The decimal value of the software register. Also found in the regs.h file. This value must be used with all programs or compilers that cannot use the header file directly.

Describes whether the register can be read (r) and/or writ- ten (w).

Short description of the functio- nality of the register. A more de- tailled description is found above or below this register.

Register

Direction

Description

SPC_COMMAND

0

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.

Any constants that can be used to program the register directly are shown inserted beneath the register table.

The decimal value of the constant. Also found in the regs.h file. This value must be used with all programs or compilers that cannot use the header file directly.

Short description of the use of this con- stant.

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“.

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.

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 uses can easily use the handle

that is given back for the according board by the initialization function.

//Windows users must set hDrv to the according board number before.

//Assuming that there is only one Spectrum board installed you’ll

//have to set hDrv like this:

hDrv = 0;

SpcGetParam (hDrv, SPC_LASTERRORCODE, &lErrorCode); // Any command just to show the hDrv usage

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.
