The idea Discord on a calculator.
An ESP8266 goes online and talks to the TI-Nspire over USB serial. The calculator shows a friends list and the chat, and sends messages back.
My first project with serial, an ESP, C and Lua all at once. The code is rough on both sides, and the README says so.
Connecting
- Update the friends list in discord.tns and the token in the ESP project
- Start the program on the calculator
- Plug in the ESP and wait for Wi-Fi (the light stops blinking)
- Press Enter to start listening to serial data
Friends list One channel per friend.
friends = {
"FriendName1:channelId_1",
"FriendName2:channelId_2",
"FriendName3:channelId_3",
}
Serial protocol
- Chat message
- <m:CHANNEL_ID>MSG1||MSG2||MSG3</m>
- Internet update
- //UPDATE//ssid||password
- Channel update
- //CHANNEL//channel_id
The dock connector Built, never used.
Besides the USB-B cable I made a custom dock connector adapter from a lab cradle’s connector and a 3D-printed case. It needs system version 3.1 or older, or Ndless, and my calculator is on v6.
