Description:

There appears to be a leak in the touch_pad_isr_de/register functions. When continually registering and de-registering (don't need it to trigger right after sleep, seen in code below), I seem to be losing 32 bytes of memory each cycle.

This is just a small portion of code within a task called mode_task

Sketch:

if(cur_mode != MODE::SLEEP){
	ESP_LOGD(TAG, "Switching to SLEEP mode");
        touch_pad_isr_deregister(touch_ISR, NULL);
	for(int i = 5; i > 0; i--)
	{
		ESP_LOGD(TAG, "Sleeping in %d...", i);
		vTaskDelay(pdMS_TO_TICKS(500));
	}
}
else{
	ESP_LOGD(TAG, "Going back to sleep after infil");
}
esp_light_sleep_start();
touch_pad_read(TOUCH1, &val1);
touch_pad_read(TOUCH2, &val2);
if(val1 < TOUCH1_SENS || val2 < TOUCH2_SENS){
	xQueueOverwrite(mode_queue, &idle_mode);
	vTaskDelay(pdMS_TO_TICKS(1000));
	touch_pad_isr_register(touch_ISR, NULL);
}
