Need help with component gpio definition

Hi Bob,

Attached is a demo component with variable number of buried pins (1 to 10).

Have a nice weekend

Bob,

there is another solution available (project attached).

I have a question though. In such arrangement, pins can be accessed like

CyPins_SetPin(myPins_1_REG_0_0);

which is not very convenient.

Is there any way to access pins through their index? like

CyPins_SetPin(myPins_1_REG_0[0]);  // this won't work

Bob,

I managed to itemize pins in non-contiguous (spanning) mode. It is not quite the same as you mentioned above, but it works. Demo Project attached. The pointer array declaration came out way ugly, but it was the only way I managed it to work. Problem was due to the fact that the number of pins is variable, so its impossible to make pointers to non-existing pins.

Appreciate if you can point to a better solution.

It is matter of taste of-course: you could use one control register of PSOC3/5 and wire connect the bits to the pins you want. Then you may need to modify the specific bit of the control register or can modify several bits at once.

It will get much more difficult as needed indeed but SHOULD still be possible for up to 32 IO-s. Some more hints: combining UDB-s and preprogrammed muxes which can be configured according to the selection from user. Never mind if no help from it.
