@teastain2 Hello,
Fine with Pin 15 setup output high, LCD is working fine with only a 5V supply on the +5V pin
Have a nice day

@teastain2 Hi,
Thanks for the support, I will add the command and test
regards

Hello,
If I connect the USB cable on the display, I can measure 5V on the pin labeled 5V.
However if I connect 5V on the pin labelled 5V, the display is not working. I suppose that this pin is only an output pin or we need to activate a Gpio Pin nr XX to HIGH or something else.

Hello, is it possible to use the T display S3 pin labelled 5V as an input power supply? Or it is only an output pin…..

@caz Of course all is ok regarding UART communication...I canuse the GPS mode, the GPRS mode, wifi...AT commands , send and receive SMS..but unable to read and write to the SD card

@caz It is exactly what I have in my sketch (look at my first post)
Thanks

@caz hello, do you have a sketch to test the SD card on the SIM7600...other than the examples (they are not working here)
Regards
Papbo

@caz Yes The SD is on the right side..

@caz Hello,
Thanks for your reply.
Unfortunately I have tested my board with all the different exemples from the Arduino library and the result are always the same "SD card mount fail".
I have formated the various SD card on Windows 10 and MAC OS as FAt32 with the same result.

Hello, I try to read SD files on the T-SIM7600E, but I have only "Card Mount Failed".
in my config file I have
#include "FS.h"
#include "SD.h"
#include "SPI.h"
#define SD_MISO 2
#define SD_MOSI 15
#define SD_SCLK 14
#define SD_CS 13

and in my setup

SPI.begin(SD_SCLK, SD_MISO, SD_MOSI, SD_CS);

if(!SD.begin(SD_CS)){
Serial.println("Card Mount Failed");
return;
}
uint8_t cardType = SD.cardType();

if(cardType == CARD_NONE){
    Serial.println("No SD card attached");
    return;
}

When I run the sketch it stops at "Card mount failed"

I have tested with several SD card with a Fat32 format.
Any idea about the problem
Regards
Papbo
