SPI-Master---Slave on teensy LC #9

Hi, thanks to btmcmahan for this great library !!! I use it with a group of 50 students to build "high speed sensors" running as SPI slaves, eg: an array of 64 light sensors that can read all sensors with 1000Hz and creates an intelligent value to be picked up by SPI.

To reduce costs we would like to use the teensy LC. Is there a chance to adopt the library? What do we have to change? What is the SPI speed limit on the 48MHz teensy LC?

Thanks Roland

Hi. It's unlikely for @btcmahan to reply ... he's not very active on GitHub. Perhaps try PJRC forums?

Sorry for the delayed response. I doubt this library would work the same with a Teensy LC, because this library is custom tailored to work with the Teensy3 processor. With other devices you would probably have better luck using Arduino IDE's native SPI functions. Although I have never used a Teensy LC, so I can't really be sure.
