Hello Epichfallen,
Can you let me know which version of the IDE you are using?

I have tried to install the example project for ESP32 but the build process failed. I'm not quite experienced with esp-idf or eve.
The compiler is giving me some errors and warnings. I wonder if this is caused by the version of esp-idf. Or am I making a mistake during the process?

Hi all,
I've just tested this AN on my ESP32 and I had the same errors (ESP IDF 4.0.1)
In order to get it compiled I changed the following in the code:
- in file EVE_MCU_ESP32.c I added:
--- Code: ---#include "driver/gpio.h"
--- End code ---
- in file edian.h I placed the following lines in remark in order to suppress the warnings about redefinition:
--- Code: ---//#define __bswap16 __bswap_16
//#define __bswap32 __bswap_32
--- End code ---
After changing this I successfully compiled and flashed my ESP32 and the demo works fine.
Luckily this AN exists because it would have been too much work to get started!
Thanks for this!
PS: I also had to change the EVE_config.h to add my 3.5 QVGA display.

Hello korstiaan,
Thank you for your comments, we have passed these on to the developer to update the files according for release.

Hi,
I'm currently testing with the BT81X chip.
It all works fine BUT if my ESP32 restarts when the BT81X was in SLEEP mode, the program won't start and gets stuck at the first display list in the function EVE_Init(void).
So, it hangs in the
--- Code: ---EVE_LIB_AwaitCoProEmpty
--- End code ---
I solved it by adding the following code inside the HAL_EVE_Init(void) after HAL_ChipSelect(0) and before the // Reset the display
--- Code: --- // Set active, needed when ESP restarts when BT81X was in SLEEP mode
HAL_HostCmdWrite(0, 0x00);
MCU_Delay_500ms();
--- End code ---
Now the startup works fine and does not block when the BT81X was in SLEEP mode before the ESP32 restart.
I do not understand why the reset display won't work or is it the good way, but by adding this it works.
Complete beginning now looks like:
--- Code: ---void HAL_EVE_Init(void) {
MCU_Init();
// Set Chip Select OFF
HAL_ChipSelect(0);
// Set active, needed when ESP restarts when BT81X was in SLEEP mode
HAL_HostCmdWrite(0, 0x00);
MCU_Delay_500ms();
// Reset the display
MCU_Delay_20ms();
HAL_PowerDown(1);
MCU_Delay_20ms();
HAL_PowerDown(0);
MCU_Delay_20ms();
--- End code ---
