I've often wanted a adaptor that would allow me to hook up any kind of small single board computer that has an IO pin breakout to the atari. Some way to map the pins into the memory space, and read and write to them. Boards like the Arduino's and the raspberry pi's, for instance. Seems like you could do an awful lot with an interface like that. SIO and so forth really is just too slow for anything other than emulated disk Drives.
Hi folks. Well, I have a situation where I need to switch between, say, 2 banks of status variables.
status_reg_1: .res 2
count_reg_1: .res 2
status_reg_2: .res 2
count_reg_2: .res 2
I need to be able to switch code accessing these variables from one to the other depending on another setting, without having to have separate code. The only way I could figure out was to set up a zero page 'base' register and use (indirect),y to access the variables. When I want block 1 I put block 1's address in there, when I want block 2 I put block 2's. Is this really the only choice?
