Sample Driver Mask

At InitF cn time, no variables in the mask exist yet. You cannot pass them

into the

InitFcn. H ow ev er, in the function, you can get the string values

using the

get_param function. For ex ample:

function [baseDec, maskDisplay, maskDescription] = ...

maddiamondmm32(phase, configuration, firstChan, numChans, range, base) %#ok

vendorName = 'Diamond';

deviceName = 'MM-32';

description = 'Analog I nput';

maskType = 'addiamondmm32';

if phase ~= 2 % assume InitFcn unless phase 2

base = get_param( gcb, 'base' );

blocks = find_system(bdroot, 'FollowLinks', 'on', ...

'LookUnderMasks', 'all', 'MaskType', maskType, 'base', base);

if length(blocks) > 1

error('xPCTarget:DiamondMM32:Block',...

'Only one Diamond Systems MM-32 A/D block per ...

physical board allowed in a model - each block of ...

this type must have a distinct ISA address.');

end

return

end
