I recently separated the hardware bus communication code from my video driver code. I thought I was slick.
Then I ran into the RA8875. I had forgotten that during the initialization phase, it must run at 1/20th of the speed of normal over an SPI bus.
I already don't care for this chip. It's odd how it works, relatively slow unless you forward all the shape drawing and font drawing to the onboard functions that do it, relying on its "hardware acceleration" which shouldn't even be necessary but it only operates at 20MHz.
No other devices require a slowdown during the initialization phase.
So now I'm wondering about this. I really don't want to add that one-off to my API, but it looks like I'll have to.
If I had never factored the bus into a separate interface this wouldn't be an issue.

Oh yes, the joys of abstraction. Just write spaghetti code, then nothing is an exception because everything is an exception.  (smiley inserted by my cat as he walked over the laptop)

It's getting close to that. The bus API is kind of a mess, but a mess with a purpose, so I can't really do much about that - part of it is just the nature of driver comms.
I'd feel better about abstracting this if it wasn't sausage making.

I just ran into the strangest device - an e-paper display that's connected to an ESP32 WROVER using I2S in tandem with an 8-bit GPIO driven parallel bus alongside it.
Has anyone seen this before? I need to know so I can decide if I should factor it as another bus type or not.
Edit: I found the answer. Apparently this *is* a thing. GitHub - TobleMiner/esp_i2s_parallel: A simple parallel i2s driver for the esp32[^]

The closest I've seen is a small 16-bit color TFT screen with 8080-esque 8-bit parallel "in tandem" with SPI, but the SPI is only used to configure and then all the data flies over parallel, as such in my case I do not consider this a new bus, just a failure to pick a single bus.
Unless, of course, the I2S is exclusively used for some kind of touch control and the parallel for pixel data, in which case I would call this 2 devices with their own busses that happen to be stuck in the same physical package.

I've since found out more about it.
The display lacks a controller as a cost saving measure. The pins connect directly to the display *panel* itself, in this case an e-paper display. Ergo, it does not use SPI or anything sane, really.
The I2S is strictly used (as I understand it) to allow precise timing and DMA for transferring data over the 8 parallel pins. It's using the I2S hardware in the ESP32 to drive 8 data pins (and there are some control pins too)

So I have an older Samsung Galaxy A7 tablet, that I plan to give to my 7 year old granddaughter, since she spends a lot of her spare time playing Minecraft on it, which means I don't have the device for developing my Android apps. Grandfather's solution: Buy a Galaxy A8 for development purposes, since they are not terribly expensive. I just cannot deprive her of access to Minecraft.
And it arrived early this morning. I anxiously set it up, including the Developer Mode settings so I can connect it via wifi to my desktop where I am running Android Studio. The idea is to transfer the app under development from the desktop to the tablet via wifi for testing / debugging purposes.
I set up connection via wifi on the desktop successfully, or so I thought. Although the desktop confirmed a successful connection and Android Studio confirmed the app under development transferred correctly to the tablet. Nothing happened on the tablet. The app did not run!
I must have struggled for almost an hour, trying every conceivable combination of Developer Mode settings on the tablet. Getting close to tears, it suddenly dawned on me: Idiot! you are using the old tablet's IP address! That tablet was on a table behind me with its screen covered and I never saw the app running on that device!
Once I fixed the IP, everything worked like a charm!

If it's any consolation, a long time ago my PM called from on-site to report a problem, so I fixed it and he drove the 400 miles to collect the new EPROM, then drove back to site to install it only to find the problem was still there.
I'd programmed it with the old version, not the new ... 
He wasn't very polite to me about it.

I'm trying to use Windows Installer Projects to create a proper installer for CodeProject SenseAI Server and the various tutorials tell you to set some properties in the properties window for the project.
I right click on the project and select Properties and the window that comes up is nothing like the window in the documentation.
Then I finally realize they mean the OTHER Property window, the one you get by selecting the project and pressing F4.
Really??!!
I guess naming is hard even, for the Microsofties.

This is an example of a Bill-failure of something ... neurons ? synapses ? ... thyroid meds ? I leave it up to remind myself there are occasional brown-outs in my perfection; besides, I like the taste of humble pie I make myself.  Quote: Why not ask the author of this recent project a question on the site ? That might help narrow down the scope of the problem. If the problem is not specific to this type of app, but, is, perhaps, a more general installer issue, try posting a detailed question on the appropriate QA forums.

Chris and I are the authors.
The statement was not about anything with the SenseAI project, rather the ambiguity in the names used for different views available in Visual Studio. Once I figured out that there are two different Property Views for a Project in Visual Studio, I was able to do what I needed and follow the examples.

Sorry, Matthew ... I seemed to have missed the boat on that one

It is a given that men don't understand women. Having said that, there is one thing that I find to be particularly puzzling.
Is the emphasis most women place on their appearance, and yes, I understand that it is a generalization, and as such, subject to exceptions.
However, I just don't get the emphasis placed on hair, makeup, clothes, and God help me, shoes, seem to be at the top of the list. Also, living space, interior and exterior, and cars. 
I really don't get it. And when SWMBO starts to place those requirements on me the bickering starts. I always lose, since it is easier to give in.
Maybe some of you ladies in the lounge can reply and explain it to me.
