Hello,
The interface of the Sequencer requests a bit mask for all API.
In app_entry.c, you wrote
void HAL_GPIO_EXTI_Callback( uint16_t GPIO_Pin )
{
// switch (GPIO_Pin)
// {
// case BUTTON_SW1_Pin:
UTIL_SEQ_SetTask(1<<CFG_TASK_SW1_BUTTON_PUSHED_ID, CFG_SCH_PRIO_0);
//// break;
//// default:
//// break;
//// }
// return;
}
which is correct but in p2p_server_app.c, you wrote
void P2PS_APP_Init(void)
{
/* USER CODE BEGIN P2PS_APP_Init */
UTIL_SEQ_RegTask( CFG_TASK_SW1_BUTTON_PUSHED_ID, 0, P2PS_Send_Notification );
/* USER CODE END P2PS_APP_Init */
return;
}
which is not correct because you have been using the enum value and not the bit location.
It should be fixed this way
void P2PS_APP_Init(void)
{
/* USER CODE BEGIN P2PS_APP_Init */
UTIL_SEQ_RegTask( 1<<CFG_TASK_SW1_BUTTON_PUSHED_ID, 0, P2PS_Send_Notification );
/* USER CODE END P2PS_APP_Init */
return;
}
Generally speaking, the only way to get an HardFault with the Sequencer is to jump to a NULL callback.
There is most of the time only two reasons for this :
1/ The enum has been used in the interface whereas 1<<enum should have been used
2/ The interrupt that calls UTIL_SEQ_SetTask() is generated before UTIL_SEQ_RegTask() has been called to register the callback.
Regards.
