Play well with other SPI devices #1

Closed thinkyhead closed 9 years ago

thinkyhead commented 9 years ago

Developers like myself over at https://github.com/MarlinFirmware/Marlin/issues/1226 are scratching our heads how to get SD card reading to work alongside SPI-driven thermocouples and other SPI devices. I'm not personally familiar with the use of chip-select lines, or whether these other devices are designed to play well on SPI buses either, but perhaps you can provide some insight to guide us in the right direction....?
