3.3 Serial Data In / Serial Data Out (SDI/SDO)
On the MCP41X1 devices, pin-out limitations do not allow for individual SDI and SDO pins. On these devices, the SDI and SDO pins are multiplexed.
The MCP41X1 serial interface knows when the pin needs to change from being an input (SDI) to being an output (SDO). The Host Controller’s SDO pin must be properly protected from a drive conflict.
Please check datasheet page 41. You can see the "Typical MCP41X1 SPI Interface Connections (Host Controller Hardware SPI) " wireing.
@Matt-Ogborne you are correct, we are using full blown Plolymer 1.0. You can extend the console with any custom elements. To run a linux command you will need to use the 'exec' function under the ' file ' ubus service. ubusProvider is the place to get started.
The problem with the serial is I am on el captain and it doesn't seem to work with it
I've had one of my onions play up on my desk, while the other 2 were fine with the office wifi.
A serial connection is the way to go and a tip is when you first connect on the COM port (make sure the baud speed is 115200) is to bash a couple of keys in the terminal until you see the message "press enter to start...", then hit enter and tada! Other wise it just stays as a blank screen :/
After that run "wifisetup" and follow the instructions.
