TMS570LS1224: How to disable notification of GIO

Hello,

gioDisableNotification() disables the GIO interrupt for your selected pin. Did you give the correct bit when calling this function?

When you disable GIO interrupt, is there any pending GIO interrupt?

Hello QJ,

Thank you for your  help. The bit of gioPORTA is 5. I think it is correct for my configuration. Enabling and disabling are as below.

gioEnableNotification(gioPORTA, 5);

gioDisableNotification(gioPORTA, 5);

Do you mean that pending GIO interrupt looks like failing to disable GIO interrupt ?

I'd like to watch it longer after calling gioDisableNotification.

Kind regards

Hello,

I don't recommend to call gioInit(), gioEnableNotification() in _c_int00() which is used for startup. Please call gioInit(), gioEnableNotification(), and gioDisableNotification() in main().

After you called gioDisableNotification(), can you please check the value of GIO Interrupt Enable Set Register (GIOENASET)? If the bit 5 of GIOENASET is cleared, the GIOA05 interrupt is disabled. 

Hello QJ,

Many thanks for your recommandation. I will try it.

Warm regards

Ok, Please let me know your test result.

Hi QJ,

Thank you for your help. I'll try it and report my result. However, might I have more time ?

Kind regards
