TMS570LS1224: TMS570LS1224

Hello,
If I am understanding right, you want to toggle GIOA pin.
To do this you have to configure MCU in HALCoGen as follows:
After selecting MCU and creating project,
- Go to Driver Enable TAB and Enable GIO driver, disable all others (if not needed);
- Go to PINMUX tab and check GIOA checkbox;
- Go to GIO Tab -> Port A tab and set desired pin as output by checking DIR checkbox (here you can set pull-up/down as well);
Generate code from File menu.

In CCS:
Create an empty CCS Project with the same name as one from HALCoGen. Include project path.
Add #include gio.h
In your main.c call gioInit();
Then you can use HALCoGen APIs to command desired pin.
For example:
gioSetBit(gioPORTA, 7, 1); // This will set GIOA[7] to 1 (pin #22 pf TMS570LS1224PGE)
gioToggleBit(gioPORTA, 7); //This will toggle GIOA[7];

Function description can be found in HALCoGen Help (Help->Help topics->Files->source->gio.c).

Hope this helps.

Best regards,
Miro
