feature request get tick rate

[unsigned_char_array]

 

You can currently set tick rate using setVsyncInterval().

I want to be able to get the tickrate using getVsyncInterval(). This would make timing things in the gui easier (blinking cursor, animation speed, boot logo, etc.).

 

I made a topic about this earlier, but it got closed.

One important nuance first: setVsyncInterval() is a simulator-only API. It controls the simulator's tick pacing, but it is not the source of truth for the tick rate on target. On hardware, the tick cadence is driven by your VSYNC/display-ready signal (via OSWrappers::signalVSync), so a getVsyncInterval() would only reflect the simulator value, not the actual target frame rate.

For the use cases you mention (blinking cursor, animation speed, boot logo), the most portable approach is to define your own timing constant in application code and derive tick counts from it, so the same logic behaves identically in simulator and on target. For example:

// Single source of truth for your project's frame rate
static const float FRAME_RATE_HZ = 40.0f;
static const uint16_t ticksFromMs(uint16_t ms) { return (uint16_t)(ms * FRAME_RATE_HZ / 1000.0f); }

This avoids depending on a simulator-specific value and keeps timing consistent across both environments.

But resolution is also available: 

 

#include <touchgfx/hal/HAL.hpp>

uint16_t width = touchgfx::HAL::DISPLAY_WIDTH;
uint16_t height = touchgfx::HAL::DISPLAY_HEIGHT;

// or:

touchgfx::HAL& hal = touchgfx::HAL::getInstance();

uint16_t width = hal.getLCD().width();
uint16_t height = hal.getLCD().height();

It would be nice if there was also a frame rate available.
