Before starting on our upgrade, we do need to make one small change to the hardware on the board. This is the addition of header pins for TX, RX and GND connections to UART2, to allow us to connect to the serial console of the device. LuckFox Pico Pro with SD-Card, RTC-Battery...

Since the software implementation of ESP8266 I2C is internal, the I2C class (written for hardware I2C) of MicroPython is used for managing I2C communication in ESP8266. The default I2C pins in ESP8266 are GPIO4 (SDA) and GPIO5 (SCL). Following is a valid example of using I2C class for...
The internal calibration inside the crystal oscillator ensures that a wide range of crystals can be used, nevertheless the quality of the crystal is still a factor to consider to have reasonable phase noise and good Wi-Fi sensitivity. Refer to Table 3-1 to measure the frequency offset....

Alarms with DS3231 RTC: Setting HTTP webserver on the ESP8266: Serving HTML from the ESP32 (did not test it on the ESP8266 but it should work): Note however that what you are trying to do has some complexity, and may be difficult if you are inexperienced. Furthermore, if you are ...
2.2.5. GPIO16 Related APIs Different from other IO interfaces, GPIO16(XPD_DCDC) belongs to the RTC module instead of the general GPIO module. It can be used to wake up the chip during deep-sleep; it can be configured to input or output mode; but it cannot trigger the IO interrupt. ...
time from an NTP server using the ESP8266 NodeMCU with Arduino IDE. Getting date and time is useful in data logging projects to timestamp readings. To get time from an NTP Server, theESP8266needs to have an Internet connection and you don’t need additional hardware (like an RTC clock)....
