In PSoC Creator 3.0 whta is the error E702: Cant handle expression ''U'' in th efinal expression for
Can you show us the offending line or even post your complete project so that we all can have a look at? To do so, use
Creator -> File -> Create Workspace Bundle (minimal) and then attach the resulting archive. (do NOT use chrome, will not attach a file)
ooops! Probably a bit too much having about 230 signals with only 24 UDBs. This is a PSoC and not an FPGA.
An additional error you made is to connect one pin to an 8-bit bus which will not work.
So independent of what the meaning of the error 702 is, your design will not fit.
Thanks for your time.
actually i dont want all those pins to be connected to output. pls tell me
1. how can i pass values from USB to component i created?
You will have to use DataPath (much new to learn).
In the "Component Author Guide" are shown the register naming patterns of DataPath registers which you should re#define in your component's .h template file. There are videos concerning DataPath. I can see, that English is not your native language, but there is much material to read when you want to use DataPath objects.
This might help -

Thanks for the link.
pls tell me how many such datapath i can instantiate within a single component.
Datasheet and TRM of PSoC 3 state: there are 24 UDBs within the chip, each containing 1 DataPath (and some more stuff).
