Just a short update – in my ESP8266 code I have a driver for the SSD1306 – and one of our readers had difficulty with this some time ago. Today I read the manual. Ooh, err.
It turns out I’d put the wrong command in place – it worked if you referred to it as an OLED but not as an ssd1306.
The command for that lot incidentally is…
Well, that’s all fixed and along the way, as I happened to be testing a WEMOS + OLED Chinese rip-off board today (successfully after changing the programming mode – again for these particular boards), I’ve added some new ssd1306 commands which should make good use of this combined board.
As well as other commands – the VOLTAGE command available in the general esp8266 code is now added to the display code – handy perhaps for a simple voltmeter or keeping an eye on batteries etc.
It’s all in the project – documented, OTA available (currently version 2.2.14)
