"Wireless Made Easy!" - This example application acts as a TCP Server to which a TCP Client can connect and visualize QT7 Touch Xpro data. The touch data are also printed on an OLED Display.
Devices: WFI32E01

The sample project has been created and tested with the following Software Development Tools:
- MPLAB X IDE v6.00
- MPLAB XC32 v3.01
- MPLAB Harmony v3.6.4
- mhc v3.8.2
- csp v3.10.0
- core v3.10.0
- wireless_wifi v3.6.1
- dev_packs v3.10.0
- touch v3.11.0
- wireless_system_pic32mzw1_wfi32e01 v3.6.1
- wolfssl v4.7.0
- net v3.7.4
- crypto v3.7.5
- CMSIS-FreeRTOS v10.3.1
-
Connect QT7 Xplained Pro to Xpro Header of the WFI32E Curiosity board
-
J211 jumper shorted between pin 2-3 to get IRQ line
-
J209 open that disconnect on-board temperature sensor thus one of the slider Y-line is sharing the same pin
-
Order the OLED W click board
-
Make sure the RST pin of the OLED W click is not connected to the WFI32 Curiosity board (RB6 signal) but connected to a permanent 3.3V (here connected to J402 3V3_IN).
The RB6 signal is already connected to the QT7 Xplained Pro board and used for the Capacitive Touch Driven Shield.
With this modification, the WFI32 does not control the RESET line of the OLED W click and the display is ON all the time.
- Then attach the OLED W click to mikro BUS Header.
QT7 uses one slider and two touch buttons

The OLED W click carries a 96 x 39px white monochrome passive matrix OLED display. The display is bright, has a wide viewing angle and low power consumption. To drive the display, OLED W click features an SSD1306 controller. Check out the SSD1306 datasheet for more details.
In this demo, the OLED W click communicates with the WFI32 MCU through SPI lines.

Touch Configuration
- Clone/download the repo
- Open the
wifi_touch_oledproject with MPLAB X IDE - Build and program the code
- Follow instructions of the Wi-Fi Touch Demo to setup the interaction between the TCP Client and the TCP Server
In this sample application, the QT7 Xplained Pro LEDs are not driven. Replacing the LEDs, the OLED Display is used to visualize the Capacitive Touch data from the buttons and the slider.
