Okay, last spam before I head off to bed... :) I can get ir-kbd-i2c behavior to pretty much match lirc_zilog wrt key repeat, by simply setting init_data->polling_interval = 260; in hdpvr-i2c.c, which matches up with the delay in lirc_zilog. With the 260 interval: Event: time 1295072449.490542, -------------- Report Sync ------------ Event: time 1295072453.321206, type 4 (Misc), code 4 (ScanCode), value 15 Event: time 1295072453.321245, type 1 (Key), code 108 (Down), value 1 Event: time 1295072453.321252, -------------- Report Sync ------------ Event: time 1295072453.570512, type 1 (Key), code 108 (Down), value 0 Event: time 1295072453.570544, -------------- Report Sync ------------ Event: time 1295072453.575718, type 4 (Misc), code 4 (ScanCode), value 15 Event: time 1295072453.575744, type 1 (Key), code 108 (Down), value 1 Event: time 1295072453.575752, -------------- Report Sync ------------ Event: time 1295072453.816215, type 4 (Misc), code 4 (ScanCode), value 15 Event: time 1295072454.065515, type 1 (Key), code 108 (Down), value 0 Event: time 1295072454.065544, -------------- Report Sync ------------ Lowering this a bit, I can get split personality, one press will look like what I was originally seeing, another will look like the 260 output. Adding filtering (return 0 if buf[0] != 0x80) doesn't help any. The final thing I've noticed tonight is that ir-kbd-i2c calls rc_keydown using a value of 0 for its 3rd parameter. From rc-main.c: * @toggle: the toggle value (protocol dependent, if the protocol doesn't * support toggle values, this should be set to zero) Well, in this case, the protocol *does* use a toggle, so that's probably something that could use fixing. Not sure it actually has anything to do with the odd repeats I'm seeing. Okay, wasn't too much work to pass along toggle values too, but it didn't help any.
