This directory contains files related to the Microchip "PIC" CPU microcontroller chips. kw11l Trivial tiny program to generate a 60 Hz clock to drive the BEVNT L signal in Q-bus PDP-11s systems that don't have another way to drive that signal (such as the BA11-VA box). p84 Tiny command line utility to program Microchip PIC16F84 microcontrollers over a serial port using the "COM84" programmer circuit. Type "P84/?" to get the command line syntax. Can erase/blank check/read/write/verify chips using either merged or split Intel hex files. No forms to fill out, everything is on the command line so you can put it in a makefile or whatever. usbcpwr Firmware for using a PIC12F510 to watch the CC1/CC2 pins on a USB C host connector (attached to pins 7 and 6 of the PIC) and decide when to enable host +5V power using a TPS2001D switch (with ENA on PIC pin 2 and the /FLT pin on PIC pin 3 with a 10K pullup to +5).
