Discussion - EVE / Porting ESD to esp32-s3
« on: March 02, 2023, 10:48:32 AM »

I am wokring with an BT815 and want to port the code generated from the ESD to esp32-s3 (at least I want to try). I have studied the AN_73 (porting guide for stm32) and think I got a rough overview how the porting could work with esp32-s3.
Hay anyone done this already?


Discussion - EVE / BT815 - Wake-Up via interrupt
« on: April 10, 2022, 07:43:47 PM »

I have a question about the possibilities of the interrupt pin. I want that any touch event triggers the interrupt. Especially when the display is in power-down state. From the docs I get, that in power-down state my wanted behaviour should be default. But nothing happens, I get no interrupts at all. Where do I have to set up the interrupt in the eve3-code? (I am using Rudolphs library)
Also I test the ISR from my MCU with a random button as interrupt source and this part works just fine. When I power up the display and do the init process I also get 2 interrupts, why? I can not find the source for them...


Discussion - MCU / BT815 RGB-to-MIPI Converter and alternatives
« on: March 22, 2022, 03:22:32 PM »

I am developing a small system which includes an 5 inch display with 800x480 resolution and based on a BT815. So my setup looks something like that:
MCU <-> BT815 <-> Display/Touchscreen
Now I am thinking about bigger displays with higher resolutions. So one way is to get an BT817, which can handle these resolutions. But would it also be possible to get an RGB-to-MIPI bridge an control higher resolutions? If yes, this would be a valid way to control for example 1080p displays with an BT815 which would be great.

On the other hand I am wondering how other MCUs are working like the stm32 ones. There are controllers, which have a MIPI interface directly. But I can not find display-controllers like the BT815 with MIPI interface and also no ready-to-use modules. Why is that so? Is it more common for tablets and stuff to have just a big MCU which can handle high resolution displays and not to split it up into a smaller MCU and a separate graphics controller?
