Multiple SPI Devices

Tried a few combinations including writing cs to 0.

digitalWrite(B1,1);
digitalWrite(B10,1);

SPI1.setup({sck:A5, miso:A6, mosi:A7, baud:1000000 });

var max=require("MAX31855").connect(SPI1,B10­/*CS*/);
console.log(max.getTemp());

E.connectSDCard(SPI1,B1/*CS*/);
console.log(require("fs").readdir()); 

>echo(0);
{ "temp": 63.5, "fault": 0 }
