Make the SPI Relay protocol support multiple devices Working on programming AVR chips exposes a glaring omission in my first design of the SPI Relay: not allowing multiple devices make this task hard. I constantly have to unplug my SD card before, plug the AVR chip holder, then play a bit, then unplug the AVR holder, then replug the SD card... My prototype for a SPI relay design is built, but I haven't tested it yet. I need to adapt the code first, which is what I do here. When the prototype is tested, I'll update the SDC recipe with a new schema. 2020-09-17 09:36:16 -04:00			`[ SDC_DEVID LITN ] (spie)`

rc2014: separate SPI relay and SDC drivers My intention is to reuse the SPI relay to program AVR MCUs from a RC2014. 2020-06-29 18:48:00 -04:00			`(spix) DROP ( a crc )`
