Hey everybody, I am wondering why the OLED 0.66" displays (64x48 pixels) are somehow buggy for the D1 Wemos. After analysing a few tutorials, I realized that the display is set-up wrongly for some reason and I had to make a workaround to get the right position data. Example given. If I define the display like that (as it should be - in my opinion) Buy Wemos D1 Mini - IOT ESP8266 Based Development Board online at lowest price in India with best quality only on ElectronicsComp.com.

If you have a datasheet or sample code that uses 8-bit address, you’ll want to drop the low bit (i.e. shift the value one bit to the right), yielding an address between 0 and 127. However the addresses from 0 to 7 are not used because are reserved so the first address that can be used is 8.} The ESP8266 has an operation voltage of 3.3V that matches the needed operation voltage of the SD card module. Because the SD card module has an internal voltage regulator and logic-level shifter you could also use the VIN pin of the ESP8266 NodeMCU or the 5V pin of the ESP8266 WeMos D1 Mini to operate the SD card module, when the microcontroller board is powered via Micro-USB. . 14 56 477 58 441 283 360 89
