burnt rubber soup
Monday, December 8 2025
I woke up in the wee hours of this morning and couldn't get back to sleep, so I ended up going to my computer and, with some help from my favorite large language model, managed to fix a weird timing issue with the serial communication of my I2C slave that had been bothering me last night.
So when I woke up this morning, I felt like I could expand my I2C slave universe a little. I wanted to get it working on an LGT8F328P, a Chinese clone of the Atmega328 that is cheaper and has more features (and which I have a small pile of). I'd tried to get the slave software working on a LGT8F328P some months ago and run into reliability issues. But when I went to use it, I found that it wouldn't reliably store configuration data for the master (an ESP8266), which would be kind of a deal breaker.
Early this afternoon, I drove to the Ghettoford Hannaford (in Uptown Kingston) to get groceries that do not tend to get bought unless I buy them. This included lots of canned beans and interesting shapes of plain white pasta. Since I had the dogs with me, I decided to also get some vegan dog treats. (They used to be hard to find, but now there are several different flavors in Hannford. I opted for bone-shaped sweet-potato/peanut dog biscuits.)
Back home in Hurley, I took Charlotte for a fairly good walk considering how cold it was. To do this, I bundled up with a peacoat over my hoodie and wore what remains of my rubber boots. Snow got into my left boot as I rounded the barn at the end of the Farm Road, and for some reason I couldn't get it all out. So my left toes were pretty cold by the time I made it to the house.
I then proceeded to make another of my big pots of vegetable soup, this time with a little pickle juice and saurkraut juices as acidifiers. I also included broccoli, potatoes, celery, carrots, crushed tomatoes, pan fried mushrooms and onions, a can of kidney beans, and some "medium shell" pasta. I thought the result was pretty good, but Gretchen detected a hint of some unpleasant flavor she characterized as resembling "burnt rubber."
Despite the cold, it had been a sunny day and we'd collected some hot water, so I took a nice hot bath after my television obligations.
Later I realized my ESP8266 masters were not reliably saving to any of the I2C slaves I'd created (I now had seven of them to work with). I tried to figure out what the problem was, but appeared to be another hard-to-debug timing issue. I would have to go to sleep with another technical problem dancing around in my brain.
