> handshaking omitted for clarity Hi, Michal. Speaking for myself, I'd feel more clarity if the details were spelled out. At least explain, please, which handshake pins attach to which (or link to a schematic). > The only explanation I can think of is that when the Control > register of the 8255 is written, _something_ happens [...] That makes sense to me, but I'd be looking for the "something" on the handshake lines (not the data pins of the port). Or maybe I've misunderstood something -- always possible. cheers JeffReceived on 2018-06-10 04:00:04
