ESP-07 and i2c LCD
Posted: Tue Nov 15, 2016 4:20 am
Hello everyone,
Recently I started playing with an esp and a lcd but I can not get it to work.
First, I made this http://ediy.com.my/blog/item/133-upload ... rduino-ide and I can turn leds on and off and connect it to my wifi.
When I connect my i2c lcd 16x2 (sda=gpio04;scl=gpio05;vcc=5v), it turns one row dark and the other empty (for what i see on some videos this is normal), I upload the code but nothing works.
I tryed:
- http://www.prometec.net/esp8266-display-i2c/
- https://github.com/agnunez/ESP8266-I2C-LCD1602
- http://imaginen4tion.blogspot.pt/2015/1 ... a-i2c.html
- ...
I tested this example(https://github.com/agnunez/ESP8266-I2C- ... I2CLCD.ino) with 2 LED and one blink but the other no (maybe is too fast).
What am I doing wrong?
Thanks!
