Sure, here’s a step-by-step plan table to verify the functionality of your WeMos_D1_mini (U1). This table will help you systematically check different aspects of the microcontroller module.
Table
Step
Description
Expected Outcome
1
Power Supply Check
1.1
Connect the 5V power supply to U1:5V and U1:GND.
Power LEDs should light up.
2
Basic Communication Check
2.1
Connect a USB-to-serial adapter; RX to U1:RX and TX to U1:TX.
Serial data should be visible in the serial monitor.
2.2
Open a serial terminal at 115200 baud rate.
Receiving boot-up messages from the ESP8266.
3
GPIO Functionality Check
3.1
Write a program to toggle GPIO U1:D4 and observe the output with an LED.
LED should blink as expected.
3.2
Repeat for other GPIO pins: U1:D3, U1:D2, U1:D1, etc.
Corresponding LEDs should blink.
4
Analog Input Check
4.1
Connect a variable voltage source to U1:A0.
Analog values should be correctly read in the ESP8266.
5
I2C Functionality Check
5.1
Connect an I2C device (e.g., an I2C sensor) to U1:SCL and U1:SDA.
I2C communication should work and data from the sensor should be correctly read.
6
SPI Functionality Check
6.1
Connect an SPI device to U1:MOSI, U1:MISO, U1:SCK, and U1:CS.
SPI communication should work and data exchange should be successful.
7
WiFi Functionality Check
7.1
Write a program to connect to a WiFi network.
ESP8266 should successfully connect to the WiFi network.
7.2
Ping a known server or access a web resource using the ESP8266.
The ping/web access should be successful, demonstrating functional WiFi connectivity.
Would you like more information on any specific step, or should we proceed with writing the necessary code for some of these tests?
