| 19:19 | Removed the handler for "freeze display on STOP" to match Ian Schofield's original "LED dithering" ILS-lite patch for the Pi Zero. Leaf check-in: 7d1cd49fe2 user: tangent tags: pi-zero-ils | |
| 11:58 | Untested application of Ian Schofield's LED dithering patch, which replaces the NLS mode with a different PWM-based incandescent lamp simulator scheme than either his original ILS or my "new ILS," intended to give much the same effect while using less host CPU power, so that it can run on a Pi Zero. This checkin is very different from the patch as posted on the mailing list, but I *think* it implements the same core algorithm. It's untested because while I have a PiDP-8/I front panel and a Pi Zero W here, I don't want to tear my PiDP-8/I apart to put the two together. That's and many other reasons are why this is on a branch. check-in: de6d1f5a43 user: tangent tags: pi-zero-ils | |
