WIFIBLE - Dual WiFi 2.4-5GHz & Bluetooth Scanner

WiFi 2.4 - 5 GHz + Bluetooth Scanner whit RTL8720DN BW16 - TOUCH VERSION!

Arduino_GFX + Hardware SPI (40MHz) + Native U8g2 Fonts + English UI + Touch

WIFIBLE is...

• ULTRA FAST: 50-100x faster than Software SPI (display only)!
• Hardware SPI @ 40MHz for Display
• Software SPI for Touch (separate pins, no conflicts!)
• Arduino_GFX_Library (optimation to AmebaD)
• Native U8g2 font support
• XPT2046 Touch Screen (resistive, manual Software SPI)

Information of WiFi's: SSID, MAC, Channell, RSSI, Encryption and Type.

Information of BLE's: Name, MAC, RSSI, Manufacturer and Services.

Wiring: ST7789 Touch Screen TFT Display (HARDWARE SPI):

• VCC -> 3.3V
• GND -> GND
• SCK -> PA14 (pin 19) - Hardware SPI1
• MOSI -> PA12 (pin 20) - Hardware SPI1
• CS -> PA27 (pin 2) - Display Chip Select
• DC -> PA25 (pin 7) - Data/Command
• RST -> PA26 (pin 8) - Display Reset
• BLK -> PA30 (pin 3) - Backlight (lookup the J1 in back of you TFT for VCC 3.3V or 5V)

Touch Screen (SOFTWARE SPI - separate pins!):

• T_VCC -> 3.3V
• T_GND -> GND
• T_CLK -> PB2 (pin 5) - Software SPI Clock
• T_DIN -> PB3 (pin 6) - Software SPI MOSI
• T_DO -> PB1 (pin 4) - Software SPI MISO
• T_CS -> PA8 (pin 1) - Touch Chip Select
• T_IRQ -> (NOT in use)

Display rotation: 180° (pins at TOP!). Touch calibration: 90° rotated vs display.

REQUIRED LIBRARIES:

• GFX Library for Arduino (by moononournation)
• U8g2 (by oliver)
• WiFi (built-in AmebaD)
• BLEDevice (built-in AmebaD)
• SPI (built-in)
• NO need for XPT2046_Touchscreen library!
