Hi,

This morning I came across with the following discussion.

PSoC Creator: Enable/Disable schematic page

In the discussion, /odissey1-san, suggested to refer to the following page

Are these rubbishy ideas?

In the last answer of series of questions, there was information about

when we disabled a schematic page.

If we disable a schematic page, for example Page_2,

and generate application, there will be an additional header called "cydisabledsheets.h"

And the contents of "cydisabledsheets.h" would be

=====================

#ifndef INCLUDED_CYDISABLEDSHEETS_H

#define INCLUDED_CYDISABLEDSHEETS_H

#define Page_2__DISABLED 1u /* Page 2 */

#endif /* INCLUDED_CYDISABLEDSHEETS_H */

=====================

This means we can refer to "page"__DISABLED definition to determine if we should enable a component

and/or its associated functions.

Now in my MCU_Tester project, I have 6 schematic pages, "tty", "pwm", "adc", "i2c", "gpio", and "spi."

Each of them has only the related component.

Figure 1. schematic pages

And in "main.c" I define the top_level functions of each component along with the menu table.

When the program started, we see the splash like below

Figure 3. Splash Screen (original)

So to support page enable/disable, I modified this part as below.

If "spi__DISABLED" is not true,

define function

void do_spi(void) ;

and add menu item

{ "spi", do_spi, "spi test" },

and did same for "pwm", "adc", "i2c", "gpio."

Since if I disable "tty" this program won't be functional,

I made it an exception.

Now to test if it works, the way I expected,

at first I disabled "spi".

Figure 6. "spi" page disabled

Then I generated the application with "generate application" icon.

There appeared "cydisabledsheets.h" in the Workspace Explorer.

The contents of "cydisabledshets.h" was

Figure 7. "cydisabledsheets.h" with "spi" disabled

Now the main.c looked like below.

Note: spi related function and menu are now disabled, too.

Then I compiled and ran the program.

NOTE: There was no more "spi" command.

I tried to disable all but "tty."

Figure 10. all but "tty" page disabled

020-all-but-tty-diabled.JPG

main.c now look like

Figure 11. function / menu definition in main.c (all but "tty" disabled)

021-main_c.JPG

But to  compile this, I had a few problems, as some source files are referencing the defined values for the component(s).

Namely adc and i2c had problems.

So for the" adc_utils.h" and "adc_utils.c"  I added #if !adc_DISABLED ~ #endif after the line #include "project.h"

And did similarly for i2c related headers and sources.

Figure 12. "adc_utils.h" with #if !adc__DISABLED added to support page enable/disable

023-adc_utils_h.JPG

The splash is now quite deserted.

Figure 13. Splash Screen (with 5 schematic pages disabled)

022-splash.JPG

Then to test "recover", I  enabled all the schematic pages, again.

Figure 14. All schematic pages enabled

030-all-enabed.JPG

The "main.c" seems

Figure 15. function / menu definition in main.c (all schematic pages enabled)

The splash screen also shows usual appearance.

Welcome back to the ordinary day!

Attached is the MCU_Tester project for CY8CKIT-044 with the page enable/disable ready.
