SX9306 Evaluation Kit WIRELESS & SENSING Microcontroller (µC) The microcontroller (C8051F387) implements the firmware that provides the USB communication to the SX9306 (through I2C) and drives the associated LEDs. 2.4 LEDs 1. D1, on the left side is the Power LED. When the EVK is connected to USB port of a computer, this LED is 2. -
Page 8: Jumpers
User’s Guide SX9306 Evaluation Kit WIRELESS & SENSING 2.5 Sensors FPC and Jumpers 2.5.1 Sensors FPC There are two individual sensors (CS0, CS1) and a pair of sensors for the smart SAR engine (CS2/CS3): Figure 5 Sensors FPC 2.5.2 Power Supply Jumpers VDD and SVDD can be utilized in two ways. -
Page 9: Microcontroller To Sx9306 Header And Jumper
Diode D10 (picture above) in EVK circuit is used for protection as SVDD cannot be higher than VDD. It should be noted that even though an external supply is used for the SX9306, a USB cable is still needed for powering and communicating with the microcontroller. -
Page 10: A1, A0 And Txen Jumpers
User’s Guide SX9306 Evaluation Kit WIRELESS & SENSING 2.5.4 A1, A0 and TXEN jumpers A1 and A0 can be individually connected to high or low through the jumpers as shown in the figure below to either voltage levels. The default values set in the EVK’s GUI and firmware for addressing the device is A1 = A0 = High (or “1”... -
Page 11: Sensor Status
User’s Guide SX9306 Evaluation Kit WIRELESS & SENSING 3.1 Sensor Status Figure 10 Sensor Status a- Combined mode OFF, Smart SAR engine OFF b- Combined mode OFF, Smart SAR engine ON c- Combined mode ON, Smart SAR engine OFF d- Combined mode ON, Smart SAR engine ON Here, CS (Cap Sensor) is labeled as Channel so we have CS0 being Channel 0, CS1 being Channel 1, and so on. -
Page 12: Registers
User’s Guide SX9306 Evaluation Kit WIRELESS & SENSING 3.2 Registers The Registers section allows reading and writing to the registers directly. Registers are either read only or read/write capable which is shown by the “Read” and “Write” buttons on the Access column. To write to a register that is read/write capable, you should double click of the data area of the same register and type your desired value of that register. -
