| 03:08 | Fixes to get things building again on my pi. Pruned a couple superfluous lines I'd previously made in auto.def. TODO: See if I can get pidp8i-test blinking lights again. Leaf check-in: 6fb29f08a2 user: poetnerd tags: pi5 | |
| 00:26 | Split out the gpio stuff so that it does not build on non-Pi Platforms unless forced with a new binary option "force-pidp8i". Required adding a bunch of #ifdef PIDP8I in SIMH/PDP8/pdp8_cpu.c. Ripped out the bcm_host stuff because I think it's invalid for pinctrl. Passes tests on the Mac. Now let's see what I broke on the Pi side. TODO: Clean up what are probably messy approaches in auto.def check-in: d0a4868e9b user: poetnerd tags: pi5 | |

| 18:16 | Took an updated pinctrl from upstream. Removed use of pinctrl.o. We don't seem to need it, and so we don't need to remove main etc. from it. Rolled back my change to gpiochip.h. Going to disable gpio builds on non-pi platforms. check-in: 1bf02a37f0 user: poetnerd tags: pi5 | |

| 21:12 | First attempt to integrate new gpio handler from Oscar Vermeulen. Won't build on the Mac because pinctrl.c uses non-portable reallocarray. Gotta fix that. check-in: b468cd1c6f user: poetnerd tags: pi5 | |

| 05:20 | Removed the test for the pidp8i-test -v flag. It was added in 20170401 with the intent of printing the software configuration string and exiting, but it no longer works, if it ever did. check-in: 24803b41aa user: tangent tags: trunk | |

| 19:48 | Here is the cycle-realistic version. For some reason, Fossil is not picking up some changes to pidp8i.h as well. This is needed in pidp8i.h: typedef enum { pft_stopped, /* the cpu is not running */ pft_running, /* the cpu is running */ pft_go, /* the cpu is (re-) starting from being stopped */ pft_exit /* exit(ing) SIMH */ } pidp8i_flow_t; check-in: 03fb9d8dc5 user: stevet tags: cycle-realistic | |

| 21:20 | First apparently working version of the cycle-realistic PiDP-8/I. This makes the Sing Step switch on the PiDP-8/I front panel behave the same as on a real -8 (subject to a minor risk that MA and MB may not be 100% correct in all major states). See the thread "New, experimental, (hopefully) cycle-realistic version of the PiDP-8/I" in the user group for more information about how to use it. check-in: 241d799d53 user: stevet tags: cycle-realistic | |

| 01:16 | First version of fixes. "Why are the ILS equations now not symmetrical excepting the scaling factor?" https://tangentsoft.com/pidp8i/tktview?name=135d14a0c2 "Extremely low throttle values cause blinky display" https://tangentsoft.com/pidp8i/tktview?name=b8d9865f31 Perhaps also "ILS brightness takes seconds to settle at low throttle values" https://tangentsoft.com/pidp8i/tktview?name=26cc6b3614 In the initial test version I deliberately exaggerated the rise and decay delays just so that people testing this are convinced this is really still doing a "lamp" simulation. Perhaps one should make those settings user configurable anyway. Still to do: fix some code indentation, check if there are comments that are no longer describing the current code, check if the timing of the switch management is still ok. Leaf check-in: 44e6476477 user: HBEggenstein tags: led-update-fixes | |
| 00:09 | Begin branch to fix some LED update issues: -prevent excessive undersampling of the LED states especially with high (unthrottled) instructions-per-second rates -speed up the ILS thread by reducing the number of GPIO switching -fix a bug in the calculation of the target brightness when the number of sampled instructions is rel. low (say < 100) -improve double buffering of LED "display" : swap displays only when updates were made (helps with extremly aggressive throttling) check-in: febe31baea user: HBEggenstein tags: led-update-fixes | |

| 22:41 | in order to check whether a deposit is made to nonexistent memory, the memory size need to be passed now in the handle_flow_control_switches function. Now the code even compiles.. Leaf check-in: 01aa183fda user: HBEggenstein tags: fix-dep-exam-ignore-if | |

| 14:16 | I2CB: build process, documentation improvements As this feature is still experimental and to allow the continuous integration to build the simh executable without th installed dependencies (libi2cd), the I2CB device logic is not included in the build by default for now, but configure offers the --i2c-bridge option to enable it, provided the libi2cd lib and header file can be found.

| 07:54 | I2CB: reformatted source code, added some documentation, changed (C) remark as per Warren Young's feedback check-in: 3a58bc038e user: HBEggenstein tags: i2c-bridge-device | |
| 00:38 | Restored a space present in an upstream SIMH file to prevent a pointless merge conflict. check-in: fab3f7655b user: tangent tags: i2c-bridge-device | |
| 00:25 | Began a new ChangeLog entry with this branch's contribution as its first entry. check-in: bf5d1b8113 user: tangent tags: i2c-bridge-device | |
| 00:04 | Removed the "PiDP add" and "PiDP end" comments. Those markers are only for injections into upstream files; this one's new. check-in: 151d16011d user: tangent tags: i2c-bridge-device | |

| 23:07 | Initial commit to start a branch exploring the idea of having a generic SIMH device that will forward IOT instructions for configurable PDP-8 devices so they can be implemented on external hardware, typically a microcontroller connected to the host via I2C. This could be used for rapid prototyping of either historical device emulation or emulating custom I/O logic. check-in: fbcfafaf43 user: HBEggenstein tags: i2c-bridge-device | |

2021-04-23

| 19:51 | Updated to the latest SIMH to fix a problem with TSS/8 booting. It seems they updated some of the device handling since the Feb 3 update we did just prior to the current stable release. check-in: f02ebe72df user: tangent tags: trunk | |
