Hi Ti team,
I followed the example to create a Task, but I've noticed that adding an extra Task increases power consumption. Is there a way to resolve this?
int main()
{
/* Register Application callback to trap asserts raised in the Stack */
halAssertCback = AssertHandler;
RegisterAssertCback(AssertHandler);
Board_init();
/* Update User Configuration of the stack */
user0Cfg.appServiceInfo->timerTickPeriod = ICall_getTickPeriod();
user0Cfg.appServiceInfo->timerMaxMillisecond = ICall_getMaxMSecs();
/* Initialize all applications tasks */
appMain();
sub_proc();
/* Start the FreeRTOS scheduler */
vTaskStartScheduler();
return 0;
}
void *emsThread(void *arg0)
{
/* Configure the LED pin */
GPIO_setConfig(CONFIG_GPIO_LED_0, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
GPIO_setConfig(CONFIG_GPIO_LED_1, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
/* Turn on user LED to indicate successful initialization */
GPIO_write(CONFIG_GPIO_LED_0, CONFIG_GPIO_LED_OFF);
GPIO_write(CONFIG_GPIO_LED_1, CONFIG_GPIO_LED_OFF);
while(1)
{
if(connection_LED == 0)
{
if (sem_trywait(&sem) == 0)
{
UART2_write(uart, (char*)"device disconnect OK!\r\n", strlen((char*)"device disconnect OK!\r\n"), NULL);
}
GPIO_toggle(CONFIG_GPIO_LED_0);
GPIO_write(CONFIG_GPIO_LED_1, CONFIG_GPIO_LED_OFF);
// UART2_write(uart, (char*)"Please connect device\r\n", strlen((char*)"Please connect device\r\n"), NULL);
usleep(250000);
}
else

UART2_write(uart, (char*)"device connect OK!\r\n", strlen((char*)"device connect OK!\r\n"), NULL);
