- Tue Jul 24, 2018 9:07 am #77372 Hello ,
I have tested the ESP-07 using a FTDI cable and work in AT mode - and I saw it't working
now I want to upload to it a arduino code ,
wanted to know to be sure :

1. in order to upload I need :
GPIO 0 -GND
CH_PD-VCC
GPIO 2 - VCC
RST - VCC

is that true ?

2. if I want to connect a I2C LCD display to the device - can I use this setting ?

Code: Select all#include <Wire.h>

void setup() {
  int sda=2;// qui SDC del sensore
  int sdc=14;// qui SDA del sensore

  Wire.begin(sda,sdc);
}

is this the right way to create a I2C display to the device ?

3. if I want to return to AT mode , how do I upload it to the ESP-07? where can I download it?

Thanks ,
