Could i write my own protocol to connecting other device through RS-485 !? The RS485 mapping to dev/extcomm/0/0 or /dev/extcomm/1/0 !?
Sorry, My English isn't good. your mean is I can use modbus tcp through spi to access I/O.
I am programmer with B4J/Pi4J. I know, Every Neuron has one RS-485 port. Could i write my protocol to connecting other device !?
Pi4J support I2C and SPI. Could I write Java app control neuron directly(I don't want to use your Evok API) ?
