☂️ Wemos D1 Mini I2C Example

The I2C communication is one out of three possible communication protocols, the Arduino / ESP8266 is able to communicate with other devices like OLED displays, barometric pressure sensors and so on. The two other communication protocols are SPI and UART. I2C stands for Inter-Integrated Circuit was invented 1982 by Philips Semiconductor, now NXP ESP8266-Hack – Piggybacking OLED display on WeMos D1 Mini. Daniel Eichhorn on 9. June 2016. Inspired by Mike Rankin’s ( @mikerankin) beautiful crossovers between an ESP8266 ESP-01 and an 0.96 Inch OLED I2C display I decided to try if there wasn’t an easy hack to marry the two components with as little soldering as possible. What is the Wemos D1 mini Pro. The Wemos D1 mini Pro is an Arduino-like board that runs using the ESP8266 microcontroller. One of the key differences to an Arduino is that because the ESP8266 has wireless capability this can natively connect to wifi. One important difference to note is that the Wemos analogue input does not accept the same as Below is the specs. of the OLED display used: - Driver IC: SSD1306 - Resolution: 128 x 64 - Interface: I2C Wire up the OLED display to WeMos D1 Mini according to the below diagram. Using Arduino Project Guidance. Kfo April 14, 2020, 1:44am 1. Hi, So I have a Arduino Mega hooked upto a Wemos D1 Mini, Im using the Wemos as a Wifi shield as I wanted to stop using ethernet for more simplicity. I have the devices connected on SPI, I actually use the SPI header on the Arduino but couldn't get Fritzing to connect to it so did Including a while loop that puts the Chirp into sensor mode. Made for wemos, but a little bit skilled person can change it for other devices If you are planning to use it for other devices, then please consider changing HIGH and LOW for the LED and reset signal. A mini wifi boards based ESP32-S2FN4R2. Features ; based ESP32-S2FN4R2 WIFI IC ; Type-C USB ; 4MB Flash ; 2MB PSRAM ; 27x IO ; ADC, DAC, I2C, SPI, UART, USB OTG ; Compatible with LOLIN D1 mini shields ; Compatible with MicroPython, Arduino, CircuitPython and ESP-IDF ; Default firmware: MicroPython Tutorials Wemos and DS3231 RTC example. The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. Features. The Wemos ESP32-S2 is a small Wi-Fi module based on the ESP32-S2FN4R2. The S2 is a new version of the well-known Wemos D1 Mini. The biggest update to the S2 is about twice as many I/O pins in the same form factor. This means that most shields intended for the Wemos D1 Mini can also be used for this module. The Wemos S2 Mini is easy to program .
