GPIO.output(resetPin, GPIO.HIGH) # restore voltage on RST pin GPIO.cleanup() # reset pins on RPI to prevent future runtime warnings 编程模式:要将MCU置于编程模式,我们需要为ESP8266供电GPIO0接地,或者在引导时将其复位并接地GPIO0(再次,确切的电压降持续时间我不太清楚,因此请不要严格按照使用的值进...

我们可以通过进入一个宏UART_PIN_NO_CHANGE来代替引脚号,这样当前被分配的引脚将不会改变。如果管脚确认没有使用,也可以用这个宏。 // Set UART pins(TX: IO16 (UART2 default), RX: IO17 (UART2 default), RTS: IO18, CTS: IO19) ESP_ERROR_CHECK(uart_set_pin(UART_NUM_2, UART_PIN_NO_CHANGE...
3个UART接口 2个I2C接口 16个脉冲宽度调制输出通道 2个数模转换器(DAC) 2个I2S接口 10个电容传感GPIO ADC(模数转换器)和DAC(数模转换器)功能分配给特定的静态引脚。但是,您可以决定哪些管脚是UART、I2C、SPI、PWM等,您只需要在代码中分配它们。这是可能的,因为ESP32芯片的多路复用功能。
so it all needs to be connected separately. For my own use, i did not bother using switches, but instead simply used two male-female jumper cables connected to the GPIO_0 and RESET pins of the ESP-01 module and plugged them into the breadboard's common Ground pins from the Arduino UNO...
The pins for ESP8266 is also labeled as diagram 2. After done uploading the code to ESP8266, simply connect it to ESP01/01S Relay Module. Step 3: Uploading the Code For coding part, change the SSID and PASSWORD to your WiFi SSID and Password respectively. In the code, it is mentioned...

And through the pins are 5 V tolerant they are meant to work with 3.3 V ,so use them at 5 V at your own risk .And the problem which i face often . Power Issue . The Module draws a lot of current , that why best is to use external source (with common ground very important) ....
