Set_register(0X5A, ELE_CFG, 0x0C) // Enables all 12 Electrodes Set ELE_CFG to 0x00 to return to standby mode Section C - Sets touch and release thresholds for each electrode Section B - Controls filtering when data is < baseline. Wire.beginTransmission(0x5A) // select device with "beginTransmission()" I have a try with your code, and i think your code seems right, but the output data still begins from the first register:0x00.ĭigitalWrite(irqpin, HIGH) //enable pullup resistor Register5= Wire.read() // read next byte from the following register Register4= Wire.read() // read from the starting register Wire.requestFrom(DEVICE_I2C_ADDRESS, 2) // select number of bytes to get from the device (2 bytes in this case) Wire.endTransmission() // end write operation, as we just wanted to select the starting register Wire.write(0x04) // select starting register with "write()" Wire.beginTransmission(DEVICE_I2C_ADDRESS) // select device with "beginTransmission()" AD7390 DAC library : Arduino library for the AD7390 digital to analog converter (DAC) AD985X : Arduino library for AD9850 and AD9851 function generators. Typical I2C read from a selected start register goes like that for reading two bytes from register 0x04 and 0x05: #define DEVICE_I2C_ADDRESS 0x5A // this must be the I2C bus address of your device AD57X4R : Provides an SPI based interface to the AD5724R, AD5734R, and the AD5754R Quad 12-/14-/16-Bit Unipolar/Bipolar Voltage Output DACs. You will have to select the register by using a write command. for example, the i2c slave's address is 0x5A, the code Wire.requestFrom(0x5A,2) can read two 8-bits data from slave 0x5A, from the register address ox01 and 0x02.īut i want to read data from register address ,such as ox04, directly? how should i do? write internal register address - most significant byte first. The method Wire.requestFrom(address,numberofdata), the address is the slave's address, it is not the slave's register's address. TwoWire.cpp - TWI/I2C library for Wiring & Arduino. Arduino library for using PS3/PS4 controller with Hobbytronics USB host adapter & Bluetooth dongle in I2C mode - GitHub - semuconsulting/GamepadPS4BT.
