I did it! I found the one guy one youtube who is trying to do exactly what I was trying to do! You are a hero and a saint and if you want to have a sloppy make out session there is absolutely no pressure but I am available. Seriously though, thanks man. This video kicks ass and helped so much!
Thanks for this! I ran into an error whereby my codes task handler was causing the program to crash on an ESP32 board. This was my fault thought, I did not set my display driver as a static variable so it was overwritten. Silly mistake but thanks for the great video!
Jared, thanks for this great tutorial. Do you know if the default bus interface such as I2C or SPI will be in interrupt driven? Would it take advantage of DMA? I'm looking at ssd1681 the driver and couldn't find the option with DMA. Thanks.
Depends on what device you're using. I know Nordic bakes some of the DMA functionality directly in the drivers (Async UART for example). You'd have to dive into the code to understand how it works for either case.
You will have to check your devices specific driver to determine this. For Nordic parts the drivers, as far as I know, use DMA. But there are non-DMA options as well.
I have tried running this example with a esp32 wrover and a sh1106(i2c) modified with just the display, no sensor for testing lvgl. But cant get it to work. seems like the program hangs on lv_task_handler(); any idea what could be the issue? my esp32.overlay works with the cfb library
Hai sir, I'm praveen from india. I want mpu6050 sensor interface with nrf9160dk. actually i write the program but it is not statisfied in device address checking funtion.can you help me sir?

Had the same issue on the ESP32-2432S028 with an ESP32-WROOM. Increasing the Stack size fixed it for me.

Thanks for Reply,
Actually above link sample is nRF52 DK but i use the nRF9160 DK. How it's working sir?
