Introduction
The ESP8266 module can be used to control an I2C OLED SSD1306 Display. Mainly to display sensor values locally.
We currently only support text messages, 8 lines of 16 characters.
Hardware
Connect the OLED Display to the I2C interface. This display works with 3V3 and can be connected directly to the ESP module.
Connections
LCD ESP-01 GND GND VCC - SDA GPIO 0 SCL GPIO 2
Software
Custom sketch
ESP Easy
Use the device tab on the ESP Easy webinterface and create a new task by editing one of the available tasks. Select "Display - OLED 1306" from the dropdown box.
Enter template texts into lines 1 to 8. Plain text will be shown on the display exactly as entered. If you want to show a value, enclose <task name> and <value name> between brackets, separated by a hashtag.
So if you have a dallas sensor running, with taskname "Dallas", to get the temperature value, use this:
[Dallas#Temperature]
Check this sample on how to get it done:
(The IDX field will be stuffed with '1', because it's needs a value. But nothing will be send with this device)
