Write to output port of ESP-WROOM-32
Posted: Mon Feb 19, 2018 5:55 pm
I am new to ESP32. Using freeRTOS in C language for my application, I notice that the chip has individual IO pins. I need to write to an LCD character module display. This devices need the computer to write to a data port (4 or 8 bits wide) plus a couple of clock lines. I can't find the way to configure a group of lines as an output por to make a byte or nibble write. Which is the correct way to do this in C ? A small piece of code as example will be very much appreciated. Thank you.
