PT7682W/PT7686W-SAOPTC0 HDK User Guide 1. Introduction PT7682W/PT7686W-SAOPTC0 HDK for real-time operating system (RTOS) is a low-cost and easy to use Internet of Things (IoT) development platform to design, prototype, evaluate and implement IoT projects. The platform supports PT7682W/PT7686W-SAOPTC0 hardware development kit (HDK) by SAC.
PT7682W/PT7686W-SAOPTC0 HDK User Guide Figure 2. Jumpers and connectors on the PT7682W/PT7686W-SAOPTC0 HDK The description of pins (Figure 2) and their functionality is provided below. 1). CON3001 is a USB connector to debug through UART, transmit and receive a signal and supply power from the PC. The USB connectivity with the PC is supported by the on-board MK20DX128VFM5. i. Set the jumpers J2002, J2003, J2004 and J2007 on, if the board is powered by a USB connector. 2).
PT7682W/PT7686W-SAOPTC0 HDK User Guide • On Windows 7 and 8, click Device Manager. • On Windows XP, click the Hardware tab and then Device Manager. 3). In Device Manager, navigate to Ports (COM & LPT) (see Figure 3). 4). A new COM device should appear under Ports (COM & LPT) in Device Manager, as shown in Figure 3. Note the COMx port number of the serial communication port, this information is needed to send command and receive logs from the COM port.
PT7682W/PT7686W-SAOPTC0 HDK User Guide sent to the UART0 port of the chipset and the code is uploaded to the embedded flash memory through UART0. 2). Connect the board to the computer using a micro-USB cable. The development board should now be connected to the PC, as shown in Figure 2. To run the project on the PT7682W/PT7686W-SAOPTC0 HDK: 1). Set the jumpers J2002, J2003, J2004 and J2007 on. • In this mode, if the power is on, the board will load firmware from the Flash and reboot. 2).

GPIO pins to activate the LEDs 4.4 Buttons The PT7682W/PT7686W-SAOPTC0 HDK is equipped with buttons with the following functionality. The push buttons are shown in Figure 2. 1). System reset button (S2001) resets the MT7682 HDK. 2). External interrupt button (S2005). Users can configure GPIO0 as an external interrupt pin. Press the button to wake up the system from the sleep mode. 3).
PT7682W/PT7686W-SAOPTC0 HDK User Guide Use the GPIO8 and GPIO9 pins as I2C0, add pull-up resistors on the HDK or on the I2C0 daughterboard. To add pull-up resistors on the HDK, refer to the resistor locations in Figure 7. The location of R2101 is for adding the pull-up resistor for I2C0_SDA (GPIO9). The location of R2102 is for adding the pull-up resistor for I2C0_CLK (GPIO8). Figure 7. Locations of I2C pull-up resistors 4.6 RTC The PT7682W/PT7686W-SAOPTC0 HDK features an RTC module.
