I2C port on 7" hmi elecrow esp32 display
so this is the reference of the product:
7"hmi elecrow display: https://wiki.elecrow.com/index.php?title=Wizee-ESP32_7.0''_Intelligent_Touch_Screen_Wi-Fi&BLE_800*480_HMI_Display
datasheet: https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf
chip of the model: ESP32-S3-WROOM-1-N4R2
picture of the screen: https://drive.google.com/file/d/1eXFTtBIQK_FXhMClNBrtX-EPmpdgcZ1q/view?usp=sharing
so i just realise that there are no I2C port on this model, i want to use the hmi to connect mpu6050 (accelerometer) and show vibration curv.
how do i manage to connect my I2C divices?. what is the i2c pin on this model?
is there another way to connect the sensors??
im ok with doing modification the display, i dont want to buy a new one.
thanks for future answer!

Hello @the_forgeron ,
We're sorry your board is the first version and does not reserve an IIC interface.
If you need to connect an IIC device, you can use the UART0 to simulate the IIC port, but you need to connect an external pull-up resistor to ensure that it is at a high level when the bus is not occupied. And note to design a circuit to prevent short circuit damage to IO ports or I2C devices.
How do you program the UART port as an I2S port? Pin #, etc.
I was surprised to see my board did not have the ports shown in the documentation. Help please

The GPIO of UART0 are IO43, IO44
