Discussion - EVE / Concerns with ESD and generated source
« on: June 07, 2022, 08:40:59 AM »
* In contradiction to the EVE concept of a co-processor for offloading host MCU from graphics drawing,
the ESD generated source has an endless, fulltime burner loop for repeated Updates/Render (about each 5-20ms), even if the HMI didn't change!!??
What is the rational behind this?
Any chance for changing (in near future) to an event-driven (dirty-state => refresh) model?
Also note:
- what about the touch-input tags repeatedly getting swapped out+in?
- RTOS unfriendly.
- this is energy-unfriendly if battery powered.
- causes constant EMI on cables.
* the new 'Switch Page' concept is very under-documented! (e.g. hierarchical usage),
there is a 'Fill Display' show on a screenshot (Figure 44, PDF man 4.15), but undocumented!
Urgent need for new tutorial video explaining all this, sample page transition.
* There is a well hidden document BRT_AN_073 for porting ESD source to STM32L4.
Bad: the listed files are not available from bridgetek github anywhere, namely EVE_HalImpl_STM32L476GDISCOVERY.c !!??
(by pure chance I found an older 'clone' at https://github.com/kaetemi/nuklear_eve )
* please add an option to export (eclipse) source with alternative name for the entry fn, instead of main().
Thanks!
