I was contracting for a company using ESP32 and have an odd question for you: if you cut down the number of pins on the programming header (have one Ground instead of individual grounds for each pin)
do you have to tie pins on the header to the ground pin. I'm asking as we blew up two programmers. I know there were no pins shorting as I made the the cut down lead. The programmers died I'm guessing from a charge build up on the pins which weren't grounded, any idea?

It might be because you're using the ESP32 in the buff and not part of a dev board but your question is confusing to me. You shouldn't have to have individual grounds - why would you? I can't make sense of that, and you shouldn't be tying the pins on the chip to ground except the GND pins, and except through a resistor for a pulldown.

Well, the thing was I know the board had issues (to say the least) but killing two programmers? One I could believe as it might have been abused before we got hold of it. The second one was fresh out of the box. There are no more in stock at the supplier (Farnell?) didn't want to get too involved. A charge building up on unterminated pins was the only thing I could think of, but it should have been designed out.

You may have gotten knock off ESP32s. Depending on your distributor there are pirated boards out there.
My client bought 3 Freenove ESP32 WROVER dev boards. One worked.
Get them from mouser or digikey.

Would not supprise me. They only had one board assembled as they didn't have all the components for more than one and that have a load of bits missing.

I use reference boards straight from Espressif themselves for prototyping. That way I'm not dealing with unknowns like bad hardware. Espressif boards are quality.

Software not ready, incorrect layout (one IC wrong orientation). Data bus running through a board cutout. Certain components not avaiable. No funds for a board respin. Delivery first week of April, Thank I got out before anything happened. I just need to get paid now!

It sounds like a circus. Wishing you luck there.

Hmm, I think it was a case of 'Oh we can do that, I did a bit of Electronics at Uni' managment by Gant chart. Utter shambles.
|

That's funny because that's how I approach everything important, and I didn't go to uni.
Programming, electronics, etc. I tell myself "I can do that" until it becomes true.
But it works for me. It doesn't work for some people.

I wasn't working on it for two months. I just put it down and walked away.

Wouldn't that be visible on a logic analyzer or a scope? I swap things all the time, so I start measuring right away when a SPI or I2C device isn't working.... or an LED, doesn't take more than one GPIO for me to mess it up.

Not exactly. HSPI vs VSPI doesn't have to do with which pins are being used, but which internal SPI bus is being used inside the chip to drive those pins.

Entrance from a mixed (for example) acapella group (7)
Home internet + work VPN flakey at the moment, so Nopes and YAUTs etc may be delayed

Or directionless crooners?
|

Little clue as time is ticking ...
Crooners could be alternative to acapella group.
But I don't see where 'directionless' comes in.
|
|
|
|
|
Think of another word for a crooner, but I don't want tomorrow's so I'm not saying it ...

I suspect that the clue is poorly written, the parentheses shouldn't be there. Ignoring the parentheses gives the instructions for an anagram. Hopefully not the anagram for 'singers[^]'
INGRESS

Hopefully, it is the anagram for singers!
The parentheses were to indicate that the text after was one of any number of possible alternatives that could lead to the word 'singers'. I chose 'acapella group' as they explicitly do not have musical instruments so highlighting the singers rather than the songs. As another respondent has suggested, 'crooners' would have done as well.
INGRESS is the correct answer. (An ingress is an entrance and is an anagram of singers)
Especially in UK Health & Safety legislation, ingress and egress are frequently used instead of entrance and exit. In fact, that is where I first came across the word and thought it was an extremely pompous way of saying 'door'.
So, sorry, YAUT
