3 роки томуWhen the ESP32 came to the market, it was well equipped: Wi-Fi, Bluetooth, two fast cores, an ultra low power core, lots of pins, etc. One thing, however, was lacking: Native USB support like the SAMD processors, for example. This changed with the new ESP32, the ESP32-S2. Here I have two development boards. Let’s look if it is the same “killer” as the first ESP32 was.

@lmamakos 3 роки тому
I am very interested about the addition of the RISC-V core to be used as the ULP. The customer state-machine-based "CPU" before really had no development tools, and you had to hand-assemble your programs. RISC-V allows us to write code in C and target that instruction set and write "real" code. So long as it all fits in 8K for your code and data! I wonder if we can build a small RISC-V FORTH to fit in there... Hmm..

@electronash 3 роки тому
@@AndreasSpiess I'm wondering how the dev board manages to switch between the USB UART chip and native USB? I can't find schematics for a similar S2 dev board yet. Some of them just have non-populated resistors for native USB, but I guess the dev board you used can disable the USB UART chip somehow, to allow the native to take over? dl.espressif.com/dl/schematics/ESP32-S2-SAOLA-1_V1.1_schematics.pdf It looks like the SD still has SPI, though, just maybe not a dedicated SDIO interface for SD cards? So it should still support 1-bit SPI for SD cards in the same way as the ESP32?

In the Arduino IDE's settings, there is an option "Use external Editor". This is what i use when i program the Arduino. I enable this option and open the project at the same time using CLion. This allows to use the Arduino IDE's tools like easy compilation, libraries, etc... and CLion's coding assistant like autocomplete. Really boost up my production.
@AndreasSpiess 3 роки тому

@TimBodeit 3 роки тому
Once you're at the point of running CLion, is there any reason not to switch to PlatformIO (they have a CLion plugin as well) instead of the Arduino IDE? I find that the Arduino IDE is a great place to start for beginners who want to get started with minimal setup or knowledge required. Once you're working on multiple files and managing dependencies, I personally find PlatformIO much cleaner and more convenient to work with.
@akj7 3 роки тому
@@TimBodeit I believe the Arduino IDE provides more libraries (and stabilities.). For a youtuber like Herr Spiess, it reduce the complexity of this video, targetting every level of Tkinterer. Personally, i have a Cmake Script that when used with CLion, compiles the Code and uploads it directly to the board. I however still download my libraries with the arduino IDE.
@TimBodeit 3 роки тому
@@akj7 More libraries does not seem to be the case for me. Both the ESP8266 (3018) and Atmel AVRs (3345) there are more Arduino-based libraries listed with PlatformIO than I could find in the Arduino Library List for all architectures combined (3013). I totally agree with the point on video complexity. "Any level of Tinkerer" is a very good description of the use-case for the Arduino IDE. I would classify a tinkerer as someone who bodges together a one-time project by himself. For him, the Arduino IDE is a sufficient tool with very low barriers. In constrast a "developer" who maintains multiple projects over a longer period of time, shares code with a larger circle of contributors or ships Arduino code that has to work reliably in production, has different priorities. Part of making builds reproducible is to use the same versions of all dependencies no matter whos machine you're building on and what year you're building a certain version of your code in. Try running a git bisect when working with globally installed libraries. I'm not saying, that there isn't a place for the Arduino IDE. I'm just suggesting, that anyone who has arrived at a level where he uses a different Editor, should try out PlatformIO first, before writing his own makefiles around the Arduino IDEs tools.

@Spritetm 3 роки тому
On the 'no CAN bus'... it is technically true that we do not have a peripheral that we can explicitly name a 'CAN' peripheral... but do look for something called a TWAI (Two-Wire Automotive Interface) peripheral popping up. If you used CAN in the ESP32, you may find that your application runs perfectly well on a S2 using the TWAI interface as well. Also, while someone surely can write a bootloader that makes the S2 show up as a flash drive, the bootloader in ROM shows up as a composite serial port / DFU device. You can upload your sketch either using the serial port as normal, or use DFU to upload it.

Thanks a lot Andreas for another amazing vid. I am disagree in one point that "security" is not interesting for a maker. Safty first. If you can not trust your device from been hacked or not secure in production than it prevent you from making projects for production environments where your credentials have to be safe and your code have to be protected. I think espressif goes the right direction. Because of that I hope you can make a vid about this feature.
@AndreasSpiess 3 роки тому
I am not against security. The credentials should already now be save with the current ESPs. Code protection is not so important for me as I do not sell products...
@JakubChalupnik 3 роки тому
That's great news! The WiFi in low sleep is _definitely_ a game changer, because now it's possible to have e.g. ESP32 based sensors running off solar charged LiIon. Or a remote camera taking picture every minute and sending it to a server, and again with just a small solar panel. Addition of Risc-V and FSM - hmm, maybe... again, like Risc-V core running all the time and doing measurements, and waking up LX7 core to send data to server... It all depends on how much power that Risc-V will need.

Hello Andreas! Thank you very much for your informative videos that helped me a lot. I was trying to install S2 dev board in my arduino. But I could not find the esspressif arduino S2 git hub branch. Is there a way you could share that with us? Would really appreciate it as I need it for my final year project

@ZozoleonLego 3 роки тому
It's not a bug, it's a feature :) The ADC is used internally for receiving purposes, if I remember correctly.
@jeremyhogan7675 3 роки тому
I emailed Espressif about this question. Here is their response: ============ In ADC2, there are two locks used for different cases: 1. lock shared with app and WiFi: ESP32: When WiFi is using the ADC2, we assume it will never stop, so app checks the lock and return immediately if failed. ESP32-S2: The controller's control over the ADC is determined by the arbiter. There is no need to control by lock. 2. Lock shared between tasks: when several tasks sharing the ADC2, we want to guarantee all the requests will be handled. Since conversions are short (about 31us), app returns the lock very soon; we use a spinlock to stand there waiting to do conversions one by one. adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock. ============== So, my take is that they eliminated this problem. I'm no expert, so maybe someone else can parse this response and better interpret it.

Thanks for this, I was curious about it. I'm puzzled by why they chose to support the boards exclusively on Arduino and wondering if the same is true for esp-idf. Also puzzled why they decided to go back to a single core. Multi-cores is a game changer for me.
@AndreasSpiess 3 роки тому
Arduino IDE is also supported. Their main IDE is still theirs... I assume it also has a cost and power implication to have two cores.

@connecticutaggie 3 роки тому
I recall when you discussed the 8266 (which had one core) and the ESP32 I mentioned that for the ESP8266 you had to use 'yield()' in any loop if you wanted reliable WiFi communication; but, for the ESP32 that was no longer required. I assumed that this because the 2nd core could process the WiFi events independent of the Arduino code primary core. I also found that the ESP32 Arduino firmware used FreeRTOS instead; so, maybe that was the real reason. Can you clarify? Did you do any WiFi testing to detect if the S2 as any issues with dropping wireless messages?
@AndreasSpiess 3 роки тому
I did not do any Wi-Fi testing so far. But I assume they use RTOS functionality to deal with Wi-Fi.
@skudooq 3 роки тому
@Andreas: Regarding your statement on the ULP just one comment - The Finite State Machine aka FSM is the classic way known already from the ESP32 so it is as interesting as before. The new option is the Risc-V, and you're probably gonna like it over FSM since Espressif's idea is that you compile the Risc-V ULP programs from C (adding such support to the tool-chain is at least planned for the ESP-IDF). This might allow more developers (and, to put it your way, not only the tough guys) to program the UPL.
@AndreasSpiess 3 роки тому
There is a project to program the ULP in C. Unfortunately I was not able to get it running :-(
@skudooq 3 роки тому
@@AndreasSpiess I guess you will have to wait since from my point of view the ESP-IDF is still far from being ready. I didn't even succeed to get a simple ULP running in the ESP32S2 despite adhering to the documentation. When I asked for an example in the ESP-forum I got a link to download an ESP-IDF that is ESP-IDF v4.2-dev-1905-g625bd5eb1-dirty which then worked fine. So even ULP-FSM for the ESP32S2 is still work in progress. Also I was told that: "Regarding RISC-V ULP, support for this should be merged to master in the next couple of weeks." So I guess you should give it some more weeks and then give it another go.

Not a replacement for the ESP32 in most cases but one particular thing of it I will definitely find useful is the sleep with WiFi active. Will probably be using it in conjunction with a regular ESP32 having the S2 sleeping and waking up the main ESP32 when needed. What I would miss most if I were to use the S2 is the dual core as I often do things that need accurate timing that is unachievable with just one core as there are some interrupts that just cannot be disabled without making things go wrong. Is it possible to have two installations on the same PC, one for the ESP32 and one for the ESP32-S2, maybe in different folders? Or would it need to be on a different PC or a VM?

Portable mode does not use %appdata%, so no libraries or settings will overlap. Really important if you need to use altered or old version library! Just installing 2 versions ide is not enough. You really need to use portable mode in that case. Also easier to backup as you have all needed files in one folder.

Andreas, I believe the ESP32S2 is not a replacement for the original ESP32-WROOM modules, it's a branch out. The original ESP32-WROOM-32 module is now not recommended for new designs. The new ESP32-WROOM-32E is a complete drop in replacement with some upgrades, according to post on the Espressif forum, so no sweat there.
