2024.11.18                                                      
                                                                
Monday, and back to work. One minor glucose dip during the night
(treated w/a small bit of chocolate), and otherwise restful. I  
had a busy morning, with over a page of notes in the first hour,
but it did slow down a bit after that.                          
                                                                
I've worked on the ilo-teensy4.1 code. Today I expanded the i/o 
interface to support some new things: analogue output (pwm &    
tone) and setting the RTC. I've also made use of the LED on the 
Teensy as an activity indicator for block i/o operations.       
                                                                
I'll be working later this week on some additional timer stuff, 
and trying to get started on USB host support for the keyboard  
input.
