FT6X36 ISR routine

[jonsmirl]

The FT6X36 ISR needs to use xSemaphoreGiveFromISR() instead of xSemaphoreGive().

void IRAM_ATTR FT6X36::isr(void* arg) { static BaseType_t xHigherPriorityTaskWoken;

xHigherPriorityTaskWoken = pdFALSE;
/* Un-block the interrupt processing task now */
xSemaphoreGiveFromISR(TouchSemaphore, &xHigherPriorityTaskWoken);
//xQueueSendFromISR(gpio_evt_queue, &gpio_num, NULL);

}

I'm trying to figure out how the gesture support works based on this code... https://github.com/focaltech-systems/drivers-input-touchscreen-FTS_driver/blob/master/ft5x06.c

I want swipe left/right.

If you find a way to make it better please add a merge request including that and optional software gesture. But it should be optional. For example that part will only return a gesture if: FT_GESTURE_ENABLE

Is defined.

@jonsmirl how is going? Could you achieve something?

I discovered that LVGL already had a FT6X36 driver so I didn't need to port this one. I have switched onto the LVGL one.

Github won't let me attach, send me an email at gmail.com and I will send you the register definitions for the chip. The gestures are very easy to use. First you enable them. And then there is a register where you read the gesture ID. All of the recognition is done on the chip.
