Jan 21, 2016 · If you leave TXD0 (UART0's TX pin), IO2, and IO5 floating, then IO0 determines the chip's mode. I wired up an SPDT switch to toggle the state as I needed. Here's a quick diagram of my simple ESP32 hookup, including a reset button, run/program switch, and a status LED:
ESP32 has three Serial ports. UART0, UART1 and UART2.. This function is used to configure the UART pin in ESP32. Using this function we can select any pin as a TX, RX, CTS and RTS. This API is used to read the data from UART buffer.
A new small size OLED, display on 128*64, and two types of interface IIC and SPI (on two different boards). Features: Drive IC is SSD1306, easy to find arduino library for it. Wide input voltage: 2.5V-5.5V Wide display agnle 160 degree. Super low power consumption only 0.06W on regular display, not TFT display can compare.

Learn how to use ESP32 PWM with Arduino IDE: ESP32 PWM with Arduino IDE. I2C. The ESP32 has two I2C channels and any pin can be set as SDA or SCL. When using the ESP32 with the Arduino IDE, the default I2C pins are: GPIO 21 (SDA) GPIO 22 (SCL) If you want to use other pins, when using the wire library, you just need to call: Wire.begin(SDA, SCL);
There are three UART controllers available on the ESP32 chip. They are compatible with UART-enabled devices from various manufacturers. All UART controllers integrated in the ESP32 feature an identical set of registers for ease of programming and flexibility. In this documentation, these controllers are referred to as UART0, UART1, and UART2.

ESP32 supports 3 Serial ports so you need not to use SoftwareSerial as in general Arduino. It has some important interfaces: - HardwareSerial(int uart_nr): this is the constructor of HardwareSerial where uart_nr is 0, 1 or 2 so we have maximum 3 Serial ports.
