Indeed he does. I would bet he does not know anout ESD and what to do about it.

His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

If you're talking about me, I do indeed and the solution is to ground yourself. Come on.

Not to forget your tools and your workspace. And the cat. Seriously, ESD can also cause very interesting problems even when the Chinamen delivered something that actually works.

I'm relatively lucky as where I live it's humid and we don't have carpet. We do have cats but they leave my electronics alone. =)
Mostly with my own junk I'm not as careful as I am with stuff I'm doing for work, like i am now. The stuff is so cheap these days I guess I'm not so worried about it. The biggest hassle is the mail. I've never fried anything with ESD to my knowledge. *knock on wood*

Ada does a lot of training and supplies a lot of code with there stuff. If you're just learning the price is justified by the extras they supply. Once you get on your feet you buy what you can afford.

That's fair enough - but their Huzzah ESP32 feather board doesn't work properly and they want $20 for the thing. They also don't seem to know a lot about the ESP32.
Here's what happened to one person trying to use one with the exact same screen I am using:
Nuts and Volts - January/February 2019 Build an Internet Digital Clock[^]
Adafruit staff literally called the ESP32 "weird" and "unstable" but it's not.
They don't know how it works.

I bought a programmer and motor control board from them years ago, they both still work by the way, but haven't bought anything since because of price and outrageous shipping.

yeah and those are a little simpler than interfacing with an ESP32 I imagine. I think they just rushed the board without knowing the chip.

I've used several of the Esp knockoff boards from various vendors and not had any problems, other than of my own doing.
Don't remember the site but there's a guy that has a free book with everything you'd ever care to know about the ESP boards. Not at my computer and terrible memory.

I've got a good board coming in the mail. Half the price and known to work with the touchscreen i'm wiring up to it.
yeah, the knockoffs are sometimes better.

Depends on the board, some knockoffs are impossible to work with.

Yeah, I don't mean all of them. SongHe makes a good Arduino Mega 2560+WiFi R3 knockoff.
Elegoo makes a decent plain jane mega
And I hear HiLetgo's ESP WROOM-32 is solid.

Despite the idiocy of the support person, according to that article the ESP32 board is innocent. The screen was designed to be incompatible with anything but an Arduino.  
Quote: After digging into the RA8875 software, I found that on initialization of the SPI interface, it begins by reading a register and checking the return value. If that value doesn’t match what an Arduino returns, it simply quits. I did open an issue with the RA8875 library and hopefully Adafruit will address the problem. I also tested a Teensy 3.1 with the RA8875 and it worked fine.

How come it works with a knockoff ESP32 board I bought though? I'm not sure it's arduino based. Looks more like a feather board to me. <--- probably my board is arduino based or something...
Good on you for finding that though. I didn't see it. Looking at it more it looks like you're right.
I'd fire that tech support person or at least put them in the mail room. When I google it that's what comes up.

A friend who was an electronics geek--this was in the early '70s--told me that ESD was such an issue for certain devices that some folks worked in the nude. I don't know much about such things, so he might just have been putting me on.

These certain devices are all of the CMOS flavor. In the 70s there just appearing and also seen as 'weird', Now they are everywhere and CMOS has been improved over the years, including making the chips less vulnerable to ESD.
And yes, it's hard to ground all of your clothing, so the safest way to protect your new sinfully expensive CMOS parts would be to wear minimal clothing while you handle them.

Why don't you ask also Expressif itself?

Because the problem isn't the ESP32. They work fine. The problem is adafruit. Adafruit needs to close their doors and take up building solar powered calculators. It's all their qualified for.

Didn't they (Adafruit folks) expose directly the ESP32 SPI pins on the board?

Yes, they exposed the ESP32 SPI pins on their unstable board. Why do you ask?
The worst part is they're still selling the trash. And when you go to the forums to ask them for help they blame it on the ESP32 being "unstable and weird" - they actually said that! tossers.

If they expose directly the ESP32 SPI pins, how could you blame them?
I mean, assuming the chip is correctly powered, if the SPI does not behave as it should then it cannot be a problem of the board.
Also, in my experience, interfacing SPI displays is tricky.

My first thought is it wasn't powered correctly, and my first suspect is cheap capacitors or otherwise cheap voltage regulation. That's just a guess though, it could be anything. These aren't exactly simple devices despite the cost.

I have used the standard ESP32 board for a complicated project using I2C, SPI, Wifi and ULP code. Worked like a charm, never noticed anything weird or unstable about it. Probably a case of wanting to shift the blame to someone else.
