How can I activate UART1 on ESP-12E
Posted: Wed Jan 30, 2019 2:38 amHi. I'm making small-sized mobile robot controlled by ESP-12E
I need to use two UART line and saw GPIO8 and GPIO2 can be used as UART1 pin.
But in a datasheet published by AiThinker, Pin map table doesn't show GPIO8 can be used as UART1RX pin. So I tested if I can use Serial1 class on Arduino IDE. I could compile the code but it seemed that it doesn't work when I connected it with PC via FT232 module.
Is it possible to use UART1 RX/TX on ESP-12E? If so, how can I set those pins on Arduino IDE?
Below tables were captured from ESP-12E datasheet (https://www.kloppenborg.net/images/blog ... -specs.pdf)
