XtsTiESP

Xtase - fgalliat @Aug 2020

• try tu reuse a Ti92(model 1-no asm) as Keyboard for an ESP32 + ILI9341 + SDCard

• it uses my other project : https://github.com/fgalliat/XtsTiLink_gh.git (for the calc & link part)

• libraries :

  • SdFat
  • TFT_eSPI

• hardware :

  • ESP32 mini
  • Adafruit ProtoShield (for UNO)
  • ILI9341
  • SDCard reader
  • Buzzer / LED
  • -- Ti92 / Arduino ProMini 5v (328P) --

• devboard :

  • TODO:

    • Board wiring diagram
    • Soldering
      • SCL & SDA
      • maybe Aref to Vcc (SCL,SDA,Vcc,GND ~kinda GROVE)
      • 8pins headers for Screen on lower-board
      • SDCard Reader on upper board / cut pins @ bottom
      • SDCard to SPI SD (code wrote / works!)
      • Screen SPI missing solders (MISO,MOSI, SCK)
      • some solders between lower & upper boards
      • SPI Screen just next SPI 8pins headers (test it)
      • Additional Button (PULL_UP)
    • test SDCard custom SPI config
    • test ILI custom SPI config
    • test all UARTs (0, 1, x) - fixed UART1
    • protect SerialX from 5v logic (switchable)
    • BUZZER / LED

  • Diagram :

    • DevBoard !! NOT UNO Compatible !! (even if same form factor)

    

    • ESP32 mini (HW665) (Arduino IDE : WEMOS D1 MINI ESP32)

      

      !! BEWARE RX1 is on GPIO16 now

• ideas :

  • webServer w/ DnD + UPLOAD
    • secure POST request w/ a token (~AUTH form) (done)
    • emit onERROR u_send() message & lock process (done)
    • add SoftAP / STA mode switcher (w/ SoftAP fallback)
    • add SoftAP / STA - SSID:psk file support + API (? /etc/wifi.psk ?)
  • BT Server / HID Server
  • connected to XtsTiLink/Ti92 system (of my own)
