ok heres the example that adafruit put out for the feather wing joy. #include "Adafruit_seesaw.h" Adafruit_seesaw ss; #define BUTTON_RIGHT 6 #define BUTTON_DOWN 7 #define BUTTON_LEFT 9 #define BUTTON_UP 10 #define BUTTON_SEL 14 uint32_t button_mask = (1 << BUTTON_RIGHT) | (1 << BUTTON_DOWN) | (1 << ...

Ive been working trying to learn more about the esp32 does and ran across the battery monitor. And i dont understand how it works. Do i need to add a wire to a pin on the battery to the board? How does it indicate battery life? Is there a way to see it on a tft? Where can i find example code?

Im having the same problem. I want to use two featherwing joys with a huzzah32. I read up on the hardware part so i know what its doing there. I cant find the programming part or where the pins are named. I also dont see any thing called sensor.begin in the wire.h library. Im new to I2c and need a w...

Im using a Huzzah 32 esp32 board that comes with one I2c configured but i need two so i can use two I2c devices. I know i can pretty much change any pin to any thing but i cant find any example code for how to do so.

I've been studying the NES emu for the esp32 and I have a few questions. I found the nes inputs files here... https://github.com/espressif/esp32-nesemu/blob/master/components/nofrendo/nes/nesinput.h and the playstation controller stuff here.... https://github.com/espressif/esp32-nesemu/blob/master/c...

What I mean is using the ESP32 as a serial communication device or bridge to update firmware on another device. I could have swore I read that this could be done but oh well.

Hi guys I need an FTDI adapter for a project I'm working on. I know that the esp32 can be used as an FTDI but I can't find any info on doing so. Do I need to flash the drivers onto the board first? Where can I find them? Which pins do I need to use? Is there a tutorial or any thing? Any help would b...

Hi guys Ive been playing around with my esp32 for a few days now and just noticed a couple things in the uploading area. First when i compile the white messages ar the bottom after compiling only show a million and five hundred some odd bytes. But the wroom chips are advertised as 4mb. I also notice...

Ok I'm trying to use the digital IO's on the board as button inputs. I was told I could name any pin on the board as what I wanted it to be. So my program above should read the settings file for the PIN numbers then configure them to work as inputs with it set as input pull up. Don't really know muc...

Any thing? Clues, hints, suggestions, links, explanations, etc. Maybe I have the ground pin for the pad wrong? Also I moved my whole game sketch into the esp32 and when I compile it says its using 2 points more storage space than what the teensy 3.6 uses. Plus it costs 110,000 some odd more bytes th...
