Virgil Dupras	2d54c3243d	grid: add CLRLN and change _lf behavior ... Instead of clearing the rest of the line on a _lf, it's simpler to just clear any new line we're entering into.	2020-11-10 19:35:47 -05:00
Virgil Dupras	e0bcf3473e	Adjust Grid subsystem ... Rename ROWS to LINES (it's what VE uses). Also, don't use COLS and LINES as immediates in the Grid subsystem: we expect those words to be available at runtime.	2020-11-10 19:06:39 -05:00
Virgil Dupras	b97e761942	Add Grid subsystem ... The goal is to offload the SMS VDP driver a little bit.	2020-11-09 17:26:15 -05:00
Virgil Dupras	1a6a549857	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 09:48:55 -04:00
Virgil Dupras	124da6adec	Move SD Card subsystem outside of RC2014 recipe and add protocols ... Although the SPI Relay driver is RC2014-specific, the SD Card driver is generic enough to be a subsystem. That's the second subsystem we add and this warrants, I think, the formalization of a new concept: protocols.	2020-08-16 14:30:33 -04:00
