Tasmota supports several I2C devices. To use them I2C and the device need to be enabled at compile time. I2C and some devices are supported also in the official releases. Devices can be de/-actived on runtime to solve possible address conflicts. (e.g. address 0x27 is used by multiple devices) Using command I2cDriver individual drivers can be
sure - but checking the status of 2 pins takes only a few micro-seconds --> that won't kill your performance even if it's just a WeMos (compared to wifi latency and other operations) I'm sure you check in the main loop() the value of your counter --> so you do execute a test anyway each time you run the loop.
Wemos d1 mini adalah sebuah board mikrokontroler dengan tambahan fungsi untuk bisa dihubungkan ke jaringan Wifi. Wemos jenis ini merupakan versi paling rendah dimana versi tertinggi dari board mikrokontroler ini adalah Wemos D1 R2. Akan tetapi wemos d1 mini ini sangat banyak peminatnya dikarenakan bentuknya yang sangat simpel, tipis dan praktis.
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.
Description. This Realtime clock and microSD shield is designed to be used with the WeMos mini & mini Pro ESP8266 based development boards. Adding this shield to your WeMos mini development board provides it with the ability to store data in a microSD card as well as use on board RTC for time keeping. Included with the shield is a set of header
WEMOS D1 R32 Contents. WEMOS D1 R32. Hardware. Configuration. Uploading. Debugging. Frameworks. Hardware Platform Espressif 32: ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and Bluetooth. ESP32 integrates an antenna switch, RF balun, power amplifier, low-noise receive amplifier, filters, and I2C Interface with communication speeds up to 1 MHz and two user selectable addresses. I bought the following module. If you’re using an Wemos simply connect the VIN pin to the 3v3 voltage pin, GND to ground, SCL to I2C Clock (D1) and SDA to I2C Data (D2). Here is a layout drawn up in fritzing to illustrate this. Layout . Code based ESP32-C3 WIFI & Bluetooth LE RISC-V Single-Core CPU. Type-C USB. 4MB Flash. 12x IO. 1x WS2812 RGB LED. 1x LOLIN I2C Port. 1x Battery port with 500mA charging. ADC, I2C, SPI, UART. Compatible with LOLIN D1 mini shields. Pinterest. This is a 2.4 inch TFT shield for a Wemos, its a large shield thats more than twice the size of a D1 mini but its an excellent little TFT screen and there are a couple of example to let you get up and running quick unlike some of the Arduino TFT shields which I have had trouble with in the past. This is a picture of the shield. .
