Circuit design  

TP6706 gyro module offers high performance and accurate gyro circuit.

1. Power supply

The operating power of TP6706 is recommended between 2.7V and 3.3V. The power is shared by the gyroscope and TP6706, if the power is output of regulator which voltage is compatible with the gyro sensor. To avoid power noise, we add two bypass capacitance. 

2. SPI bus interface

The TP6706 SPI is used for the slave mode. The SPI allows to write and to read the registers of the device. The Serial Interface interacts with the outside world with 4 wires: CS, SCK, SDI and SDO. When the SPI clock is at the raising edge, the data will shift/output, when the clock is at the falling edge, the data will be latch/read. 

3. Sensor signal

We support one input voltage reference pin and two analog input pins to receive the gyroscope signals. The Master SPI function to asses Digital Accelerometer. The two analog signal pins will transform the signal to USB HID mouse report format data and the data output from the SPI of TP6706. We can use the data to control cursor of monitor easily. 

4. Voltage Detector

For more and more connected devices, the issue of detecting battery voltage is important. For example, one pin is used to detect power voltage especially. If the power is below the certain voltage, TP6706 will send a message from SPI to MCU to inform that the system is close to low power. 

5. Busy State

The busy State pin is a very important pin. During the setup time for the gyroscope, the SPI transmission will not work until the busy State pin is enabled. Initially, the pin pull low, the master can select slave device by CS. The busy state pin pull high again, which means the SPI and gyroscope is ready. At this time, the TP6706 can wait for the master SCLK to receive data from MOSI.
