I'm using arduino IDE to program an ESP32-WROOM-32D module. The code upload is successful however after uploading the code on the serial terminal I'm getting :

rst:0x8 (TG1WDT_SYS_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv ...

I was trying out the capacitive touch of ESP-32 using arduino IDE. this is my code :

void setup()
{
Serial.begin(115200);
delay(1000); // give me time to bring up serial monitor
Serial.println("ESP32 Touch Test");
}

void loop()
{
Serial.println(touchRead(T0)); // get value using T0
delay ...

Thanks @thorvard Now it is working well with digitalRead however if I put in the following code.
It does not work properly and digitalRead gives zero even at 3.3 v analog input. Can I use both digital Read and analog read on the same pin?

void setup() {
// put your setup code here, to run once ...

I have read about the linearity issue on esp forums.
I recently did a test on it and found the following result (I am using the analog read function on the arduino IDE) :

the excel sheet attached has the input value and the output no. of the esp.

It is pretty linear ...

I was trying to digital read (using arduino IDE) on my pin GPIO34 of esp32. However digitalRead(34), returns 0 irrespective of whether I press the button or not. I have connected the pin to 3.3 V sourse using a push button. Is there something I am doing wrong as the function works fine on pin 19 or ...

Can we connect the ESP 32 module with a FTDI (USB to serial converter) just the way we connect an esp8266?
If yes can anyone tell me how to do it. It would be a great help. Thanks in advance.
