#1046 Support of Raspberry SPS

[Gerd Kainz]

There exists a nice system called Raspberry SPS (raspberry-sps.de). The attached paches implement support for the provided I/O boards. The support has been added to the IDE and FORTE.

Vorgänger: 1503 (3b44c7cd674d) Merge with 1.7.x
Vorgänger: 144 (70aea06a1af5) Merge

Attached is a type correction of the IW and QW blocks.

Corrected the access method for the ADCes of the Raspberry SPS.

Now, everything works fine.

thank you for the patches I added patch 146 in cset[fordiac-lib:19ed6a] the other patches will be added soon

[Zoitl Alois]

I finally found some time to review the FORTE patches. First of all thanks for the work it is great to have more I/O support. There are some issues I would discuss with you before applying the patches:

• From a code reuse perspective wouldn't it be better to merge the CWordAccess with CProcessInterface?
• You implemented only the REQ/CNF interface for IX. In the latest version there is also in IND output event. Would it be much effort to add it?

BR,
Alois

• Merging CWordAccess and CProcessInterface would make sense, but this requires the implementation of IX, QX, IW and QW on all platforms. Alternatively, a common base class of CProcessInterface and CWordAccess would make sense.
• I know about IND but not how it works. If I get that information, implemenation shall be easy.

Merging CWordAccess and CProcessInterface would make sense, but this requires the implementation of IX, QX, IW and QW on all platforms.

Not necessarily. If IW and QW just use two additional functions of CProcessinterface (i.e, writeWord, readWord) only the platforms providing IW and QW need to add these function blocks. As the design pattern we are using here is half template based this should scale quite flexible and platforms not supporting IW and QW would not be affected.
