    Arduino Morse Decoder

    Hi kangetsusorry for late reply, I am not sure how to upload the entire code, check the connections between the Arduino and the LCD, they should be smthg like:LCD Arduino/protobrdK GNDA 100ohm resistor to vcc (5V)D7 D2D6 D3D5 D4D4 D5E D11RW GNDRS D12V0 100ohm resistor to GNDVDD Vcc - 5VVSS GNDResistor values could be changed to adjust the backlight and char light to your needshope it helps!!

    Just to be more precise, I had to use a different library for the 1602A:#include <LiquidCrystal.h>Initializing the LCD with pins:LiquidCrystal lcd(12, 11, 5, 4, 3, 2);Then take into account it has 2 rows and 16 columns in the setup lcd.begin(16, 2);And also in the upd function x++; if (x >= 16) { if (y >= 2) {I hope it helps!

    Finally managed to do it with a D1 Mini instead, with this connections taken from examples:/* ###################################### * Hardware Wemos D1 mini SPI pins D5 GPIO14 CLK - D0 pin OLED display D6 GPIO12 MISO (DIN) - not connected D7 GPIO13 MOSI (DOUT) - D1 pin OLED display D1 GPIO5 RST - RST pin OLED display D2 GPIO4 DC - DC pin OLED D8 GPIO15 CS / SS - CS pin OLED display#########################################and the following libraries (just in case it helps):#include <Wire.h>#include <SPI.h>#include <SH1106Spi.h>#include <OLEDDisplayFonts.h>#include <OLEDDisplayUi.h>I also sorted out the icons issue. I was having quite a big mess with the libraries. It would be great to have SH1106 examples with ESP8266. Many thanks to everybody!

    Also tested with ESP-07, same connections as with the D1 Mini and// Pin definitions for SPI// ESP8266 -07#define OLED_RESET 5 // RESET#define OLED_DC 4 // Data/Command#define OLED_CS 15 // Chip selectJust in case it helps!!!!!

    I finally managed to make it work with the sh1106 library from Renemthttps://github.com/rene-mt/esp8266-oled-sh1106and a D1 Mini but the icons do not look good even when using the WeatherStationfonts.h, any ideas why?thanks once more

    Now I'm on the same page as you. I can see the Weather data downloaded but it is not shown in the Display. I have found this info:http://www.waveshare.com/wiki/1.3inch_OLED_(A)similar the adafruit link you posted below. I'm using SH1106 with I2C and ESP8266-01. As I understandSDA - GPIO0SDC - GPIO2CS should go to LowRES not sure DC or SA0 not sure eitherRgds

    thanks limeg, I got it thanks to solar767, now I do not get anything in the display, most probably because I'm using SH1106 together with ESP01, many thanks once more

    sorry, cannot find arduinoweatherfont.h anywhere, may you please let me know the library name?thanks!

    hi limeghow did you fixed it? I'm having the very same problem ...Thanks!

    Hi solar767,Sorry but I'm having a similar problem, trying to use 1,3" OLED with ESP01, no luck for the moment, ...
