Really appreciate you doing this series on ESP-32 with all the details. Would love to see this series continue and cover both basic and complex functions, hardware and software. Thanks Again Dave!

[@harrykane329]

Dave, Love your stuff. I too am a retired software engineer. I retired from Northrup Grumman 15 years ago and now at 80, I need to keep the synapses firing as it were. I built a model railroad (N Scale 1:160) which may be a bit small for my 80 year old eyes, but I actually built it to play with Arduinos. I have been having a ball with these, and recently purchased a few ESP32s. Like I said I need to keep the synapses firing as long as I can and having programmed in C++ for more than 30 years now, these micro controllers are a hoot. Like you I'm from the PDP-8 PDP-11 era even before MSDOS. I worked on the design for a PDP 11-35 emulator for Litton industries since Digital was dropping the line and 30 years later I am still playing with computers. Keep these wonderful videos coming. BTW, I can't believe you actually bought and resurrected a PDP macine. Kudos!

as a non programmer (i tried learning C++ numerous times) and home assistant user looking at esp32 this was VERY informative, i almost understand some of the programming stuff too.

[@steveb7600]

Start with python, C++ is much harder, and at this point it is a boutique language. BTW I started with C++ but I don't advise that for anyone starting these days

[@cdoublejj]

@@steveb7600 i have hard time believe these easy to use languages don't use more ram. why isn't windows 12 in python? i was told REAL men\woman program in raw machine code?

[@steveb7600]

@@cdoublejj no operating system is written in a high level language, but writing an OS isn’t a typical programming job. Also RAM really isn’t an issue anymore with languages but compile/transpile speeds and code size are. If you are really curious as to why you wouldn't write an OS in a high level language I can explain that, just let me know.

[@cdoublejj]

@@steveb7600 i believe the high level answer is that drivers in python aren't a thing lol. though while i tease and challenge your word there actually puts perspective as far as task at hand vs languages used.

[@wayland7150]

@@cdoublejj People who started back in the late '70's or '80's would probably have programmed their home computer in BASIC. To turn on a relay we would have used the POKE command and to take a sensor reading we would have used PEEK. The advantage of BASIC is that the programs run straight away, there is no compiling or downloading. You simply save your work when you reach a good stage. Using C++ puts some massive steps between you and the result. Dave makes it look easy here but home computers were much easier than this except more limited. You could do worse than go back to the place we started but use an emulator. I'm using XRoar to emulate my old Dragon 32 machine but there are ones for Commodore 64 and Sinclair Spectrum. You may quickly grow out of it, the whole scene back then was about 6 years in total and about 2 years per machine. Use this as a learning experience to give yourself confidence in BASIC the same way we did. Then move on to C or a higher level language. High level languages with the right librarys when correctly chosen make writing programs easier and faster. However C is probably 40 times better performance and Assembler 40 times better than C. But when your computer is a million times more powerful than in the 1980's it matters a lot less how fast it run than how easy it is to write.

I like the way you align the {} brackets at 12:42 Code looks much better and easier to read when all brackets are nicely aligned. The way it is done in Python and Occam is even more elegant. Nice video. It helped me to move the code for my 8 x 8 x 8 RGB LED cube to Visual Studio Code.

[@scriptles]

Yeah but I also like how much easier it is to test using { an } on seperate lines too.. so basically an if statement will execute 1 line of code... unless you use { and }.. however, if the next line is a { it does the whole block"... so if you wanna comment out an if statement and run it if the condition is false.. u can just comment out the if statement and leave the { and } for scope purposes.

[@edwardandrews9240]

Great, quick video to get me re-started on ESP32S. Things didn't work well for me, however, as I had an older ESP-32S (bought several years ago) and it suffered from "CAN NOT CONNECT" errors when trying to upload. If anyone else has this problem, try this fix which I found elsewhere: Add add an electrolytic cap (2.2 uf to 10 uf) from EN pin (+) to GND (-); this fixed things for me!

[@tookitogo]

Yep, that often helps. I think I’ve just used 1μF, though. Keeps the EN pin low long enough for the programmer to set the IO0 pin (boot mode) to bootloader mode before it starts up.

[@mikewallis7762]

Hey Dave, I have done a fair bit of work with the ESP32 and lighting strips and even individual RGB LEDs as well - it works really well for models and such. I have done a few effects like lightning, flickering fluorescent, traffic lights, LED matrix displays as model road work signs, etc. During my travels I created a project that showed me the power of the ESP32. I purchased 1 meter of NeoPixel RGB LED strip and set about seeing if I could create a task for each of the effects I had created and then apply that to each of the leds in the strip. I set this up and it worked really well. I ran 40 tasks each of which were controlling 3 LEDs on the strip. API and web interface are there as well. I would publish it, but it needs a bit more polish. Can't wait for your next instalment. Love your content.

[@mikewallis7762]

... sorry, forgot to add. Any stuff on tasks on the ESP32 you wish to share would be great. I must admit my implementations thus far do not include any sort of locking or semaphores. I just deal with that in code - dont use the same LED (pin) in two different tasks. Hope you are having a good day :)

Please also make an episode about remote debugging with openocd/ESP-PROG. Too many people out there torture themselves with println debugging just because they don't know better. Other notes: 6:05 The TTGO T-Display is my favorite board by far, the screen is great both for interaction and debugging. It also has two GPIO buttons (plus reset on the side), which makes it possible to build fairly convenient GUIs without any external hardware. Not as fancy as the M5, but for 10 bucks it is incredible value. 13:27: you have to press ctrl-c to terminate the monitor. And if all else fails, ProcessMonitor can tell you which process is blocking the COM port and help you kill it. 18:27: it is much easier to just use one of the User headers (configurable in User_Setup_Select.h), they have predefined ones for most common devices, e.g. Setup12_M5Stack.h

Also, don't forget the gigabytes of bloat, unnecessary long compiling times and the dependency/versioning hell[1] that you get for free with PlatformIO. Yes, all the things we love and like when working with MICRO controllers (!ironic!). [1] What they force you into, their package dependency system ... they seem to forgot within the build system: Dependency checking. What a botch-up, lol. Setting up a build system with a compiler and thinking about libraries before using them won't hurt anyone. In contrary, you learn more about the inner workings of the build system, think BEFORE making avoidable errors and wasting time over your project, and learn more about the architecture you are working with. All for free. You even don't have to give up editing a fancy magic text file. Just call it "notes";)

I’d love to see more about the ESP-Prog. I’ve used it and it’s saved me lots of headaches, but it’s also fickle to set up, and there are some sketches where it simply will not work at all. I’d love for someone more knowledgeable than me to explain some of the voodoo, the limitations, etc.

Thanks Dave, I found this really helpful in setting up VSCode for use with an ESP32. And thank you also for bringing autism to the front from time to time.

[@linuxgeex]

@Dave: I find when I talk to people that describing the ESP32's standby in terms of battery life helps drive it home. The ESP32's idle is roughly 10% the self-depletion rate of an 18650 cell. That is to say that an ESP32 on standby for a year, powered by an 18650 might have 30% state of charge, and 7% out of the 70% battery capacity lost was used by the ESP32's standby. So implementing an SCR to allow it to fully power itself off is a waste of time, since the SCR will consume more power than that by way of voltage drop during operation.

[@TheBypasser]

Well, a switch comes in handy should you have many on-board peripherals though.

[@dvdny]

So you’re saying that the battery leakage (18650) rate is still even higher than the standby current? Good to know.

I have been using the ESP32 in production for 5 years now. At first I only did simple things, since it was a mere replacement for my solutions with PIC or ATmel microcontrollers, but with each new client I am encouraged to add more complexity. I'm at the point where I can almost do without a Raspberry Pi. In fact, the only thing stopping me from abandoning the Raspberry Pi in favor of the ESP32 is that I still can't run node-red on any of the ESP32 variants. For now I use the Raspberry Pi as a node-red and data server, and the ESP32 carries all the hardware such as sensors, displays and actuators, both locally and/or remotely.

These are very much less complex than a PI which is really a complete general purpose computer. It's irritating to me when a whole computer is used to read a sensor and operate a light.

As a heads up for anyone who wants to use the bare modules... Look up esp32 test frame, it's a great way to program like 20 of the devices very quickly or even just one as a one off.

I got one of those TIGO VGA32 ESP32 boards ($21) which used Arduino IDE and ESP32 sketch to program, but I also got the FabGL library which implements a number of retro computer emulators, e.g., Vic20 - but I like the PC 8086 emulator which runs various MS-DOS, FreeDOS, and rather nicely CP/M-86 (which has Turbo Pascal 3.0 for CP/M!). There are various configured DOS images to select from when this is downloaded to the board for execution, which have assortment of DOS games, tools, apps, and things like various BASIC, Turbo Pascal, and Turbo C. An image gets downloaded to the board via its WiFi and gets cached to its SD storage. This board has VGA-out, audio-out, two PS/2 ports for keyboard/mouse, micro SD for storage, WiFi. The micro USB provides power and with data line is the means of connecting to a PC where development is done from. Am thinking this board would be great for rolling implementations of the Pico-8 fantasy console, and certainly various retro computers. With its VGA port and PS/2 ports, it can be a near equivalent to an IBM PS/2 Model 30 with 8086 circa 1988 when those got revved to VGA graphics standard.

I missed this one somehow. I usually catch most of your uploads. Volos Projects us a great channel for this stuff. He's a teacher from Croatia and is teaching the ESP32 to 9 and 10 year olds. There's lots for adults and many that you could work on with a kid. No wonder Eastern Europe has so many engineers. They start them young. Dronebot Workshop is great too. He covers all the microcontrollers.

I work for a school system and was looking for a platform to create an automatic bell system. I need a system that can query a web page to download the class schedule from our student information system. The esp32 looks like it will be perfect! I see that they have a relay board available too which is exactly what I need to drive the PA system. This is going to be a fun side project! Thanks!

very very helpful - and thanks for sharing

Thanks Dave, for the freaking scary firehose of information. Incredibly, I understood most of it, but only due to your excellent presentation and 40 years of experience.

Great project topic, looking forward to it.

Very helpful. Thank you!

I'm quite partial to the ePaper ESP32 boards. They don't bleed light in dark rooms, and look nice for semi-static displays.

still too expensive when compared to the I2c OLED with he ssd1306's

Sharing with friends. Good video. Looking forward to the next one.

[@jamesabernathy9744]

Enjoyed this video. I use ESP32 and ESP32-S2. I've been using Arduino but want to start using VS PlatformIO more. Thanks for the video

[@RandornCanis]

Love the ESP32-S2, but Espressif's marked many parts obsolete since announcing the ESP32-S3. Incredibly powerful replacement to the ESP32-S2 and ESP32 combined, but Arduino support is - preliminary, let's say.

[@steveb7600]

@@RandornCanis Powerful? The whole S series performs closer to a esp8266 then a normal esp32

[@steveb7600]

That board is a terrible option. The S2 is a Risc V slowpoke which is closer to an esp8266 than a normal devkitc ESP32. Silicon makers like it for the free Dave Patterson IP but no benefit for the cost for the end user.

Now I finally have a decent idea of how to do stuff with the M5stack (basic unit plus battery) that has been sat unloved on my desk for WELL over a year. I'm sure I already had a toolchain plan when I bought it in late 2020 but that is long-since forgotten - I was probably going to use the Arduino IDE, but I use VS Code for other stuff already so I might as well follow your approach. Thanks!

Thanks for the introduction! Where's the next video about implementing the Webserver?
