ESP32
Shaving the Yak
I had some trouble with conflicting libraries(?), so I decided to do a fresh install of the Arduino IDE (OSX)
- Delete Arduino IDE from Applications
- Backup/delete Arduino folder from Documents
- Tried to install new IDE in user Applications, didn't work
- Updated Java, didn't work
- Moved IDE to top-level Applications, worked
- Looks like old board defs are still there, more research required
Setup
- Install ESP32 Arduino Core
- Open Arduino IDE, select Board > Heltec Wifi Kit 32 (or match your hardware)
- Install ACROBOTIC SSD1306 Library via IDE library manager
- Note that included ACROBOTIC 1306 examples do not work out of the box (source)
ThingSpeak
- Sign up for a Matlab account
- Sign in to Thinkspeak
- Create a new channel
- Locate and copy its Write API key and Channel ID
- Edit Arduino > ESP32_Thingspeak_OLED to reflect your network's SSID/PW and your Thingspeak channel info
