Not likely as Android apps tend to work with phones which don't have the need for I2C or UART comms etc.
I wrote a couple of JNI libraries to handle GPIO, I2C and UART, you can find it here. This can be added to your project. http://www.axoninstruments.biz/download/gpioserial.zip This is just the library for I2C and UART. This is very basic code for the I2C (I omitted the required exception handling) Open the I2C device fileHandle = i2c.open("/dev/i2c-0"); Read I2C i2c.read(fileHandle, slaveAddr, buf, 3); Write I2C i2c.write(fileHandle, slaveAddr, 0, buf, 1); Close the device i2c.close(fileHandle); Buf is an int array. slaveAddr is the 7 bit address of the device you want to talk to. Serial Port is pretty much similar. I used this with a Modbus library. You only need to allocate the file handle to the streams for this to work. Search for modbus4j by Serotonin. This works great with Android. I hope this helps? On Tuesday, 30 June 2020 23:31:00 UTC+7, NANDAKUMAR S wrote: > > Thanks for your reply, > > I have tty in /dev directory.
