![]() During uploading the code if “ Connecting…._” text appears then press the RESET button of ESP8266 ESP01 until the code start uploading.After selecting Board and Port click on the Upload button.Connect Arduino and ESP01 as per the circuit (refer pic 1).Which board to you use The arduino mega 2560 is not the same as the esp8266. The i2c bus is also for short distances (because of its weak pullup signals). Check the GPIO-0 and GND pin is Connected. The spi bus is ment to be used on the same board, or else for a very short distance.Disconnect the supply from the ESP-01 module.To resolved the esptool.FatalError please do the following steps: ![]() While uploading the code to ESP8266, you may get this error “ esptool.FatalError. Here I have used Arduino UNO just to give the 3.3V supply to the ESP-01 module. Then restart the ESP-01 or you can also press the RESET button of ESP01.Īs per the code, I uploaded, the LED connected with GPIO-0 starts blinking. Si queremos iniciar una comunicación, primero debemos activar SPI con el siguiente código Arduino SPI. ![]() Also, disconnect GPIO-0 from the GND pin. I keep seeing ESP8266 projects where theyre simply being sent data from an external microcontroller, or people are attaching peripheral devices via bit-banged i2c. I have disconnected TX and RX pin from Arduino. Sketches are packed in a ZIP file: ESP8266_ILI9341_Adafruit_demo_Bodmers_clock_demo.Here, I have uploaded a simple blink example sketch to ESP8266. ESP8266_ILI9341_Adafruit_Bodmers_clock.ino, a real time analog clock example adapted from Bodmer’s TFT_eSPi library examples (display visible in figure 3). ![]()
