Hi all.

when test MAX30105 sensor, if use: TDS3+max30105+OLED without use TDS3's TFT, it works well.

this time when initialize TDS3's TFT by TFT_eSPI.h, the TFT init OK, but OLED and MAX30105 not work(no need both OLED and TFT works, just for testing);

if disable OLED and use TDS3's TFT to show the content, TDS3 stuck at the first page;

please let me know if need the testing code.

Thanks
Adam

@teastain2

that means or 5v + USB ( when charging); or 3.3V + USB (when charging) are OK.

@teastain2

Thanks.
The reason to ask is saw some where online search indicated that the USB/power pin 5v/pin 3.3v/ can only use just one. like to make sure it is not for T-Display.

Hello,
the T-Display S3 comes with power jack in the back, I'll try to use one cell of Lipo battery to power it, is it OK?

and my question is how to change the battery, can it be charged by the built-in usb port?
thanks
Adam

Hi all.
the same code, same parts, ESP32 DEV Module + Mouse_Scroll_Wheel_Rotary_Encoder works well;
the T-Display S3 + Mouse_Scroll_Wheel_Rotary_Encoder doesn't work at all, why?
Used encoder library and example:

Thanks

@teastain2 Thanks.
not work.

The example/SD just define 3 pins, and I didn't find any where mentioned SD_CS, can be a problem?

I used SD card reader with 6 pins.

@teastain2 said in T-Display-S3 (touch version) trouble to connect SD card reader (SPI):

What exact board do you have?

Thanks.
I have T-Display S3 basic + SD card.
I heard that the Touch version more difficulty to work with SD?

any thing new for now?
I tested the code above not luck.
