As with most peripherals, UART1 is configurable to use almost any GPIO the ESP32C3 has; just initialize it with the pins you want to use it on. If a pin is said to have a function wrt a peripheral, generally you can see that as the 'default' pin, not the pin that you mandatorily...
In esp32c3 technical reference 26.4.2, there is: UARTn can access FIFO via register UART_FIFO_REG. You can put data into TX FIFO by writing UART_RXFIFO_RD_BYTE, and get data in RX FIFO by reading UART_RXFIFO_RD_BYTE. If I get it right, it means that reading the lower 8 bits ...
How to use I2C in ESP32 || Interface LCD16x2This is yet another tutorial in the ESP32 series using the ESP-IDF, and today we will cover the I2C Peripheral. For the demonstration purpose, I will use the LCD1602, which is connected via the PCF8574 I2C expander....
Check this tutorial:How to use push button with ESP32 Note: The maximum operating current which GPIO pins can sink and source is 40mA according to the datasheet of ESP32 chip. But it is recommended to keep it below 20mA. All GPIO pins on initial boot-up or reset remain in the active...
ESP32 is a smart microcontroller board with built-in Wi-Fi and Bluetooth capabilities. ESP32 comes with an internal RTC, but its working is dependent on power. So if you want to design projects or circuits that you want to run even when there is no power, you must use any external RTC...

a computer, you select the board, you are using. There are many types of ESP32 boards available on market. But we are using the Dev kit in this tutorial. But you can use any board you want. To select board , go to tools>>Boards and click on Dev module as shown in picture below...
From the esp32-c3 datasheet: 'ESP32-C3 has two UART interfaces, i.e. UART0 and UART1' Note that in the ESP32 series, a lot of peripherals don't have dedicated pins (even if some have default pins) and the same goes for UART1. You can re-route the UART signals to any ...
Open that file, and change the esp32.upload.maximum_size for the board of your interest. I’m going to use the ESP32 Dev Module. Therefore, I will change the maximum upload size for the Dev Module. Now let’s see the impact in the Arduino IDE. Since we have changed the default par...
