Nice tutorial thank you for sharing. Personally I like working with the native SDK of the RP2040. Because of dual core feature, its resources can be optimized better using FreeRTOS
Now we're talking! Do the creators of the board give instructions how to get the WiFi chip working via C language, plus how to spin up a simple server or client firmware?
The WiFi chip comes packaged with Espressif's own firmware "AT Interpreter" and they have some documentation here (lots more in other sections of this site too): docs.espressif.com/projects/esp-at/en/latest/esp32/AT_Command_Set/index.html Examples including what you suggested are available here: docs.espressif.com/projects/esp-at/en/latest/esp32/AT_Command_Examples/index.html In terms of RP2040 side its as straightforward of sending a string containing your command over uart using the functions built into the Pico SDK. If needed I can have some examples up on our website probably by the end of the week!
At this price-point, it seems that whichever version of the ESP32 family would best suit the job, would be a better value, in terms of price/performance (i.e.value).
eh I'm on the fence about that. a couple of MB can get tight. for a large project this might fit the bill. don't get me wrong it's thrice the price but sometimes you just need that certain thing
Just curious, what is the data transfer speed between The RP 2040 and the ESP chip? Seems like using an UART would be like sipping through a fire hose.
Yes, John! Try looking at adafruits GITHUB repo. Search for 'Adafruit_CircuitPython_ESP_ATcontrol'. By the way - did I ever tell you that you're a very good looking man?
Have a piece of sandpaper handy, eg. 180 or 220 grit. When you get new boards ALWAYS finish the sides on the sandpaper. This gets rid of mousebites and other gribblies left over from manufacturing.
A bit "show and tell-ish", perhaps some functional testing? ...if you are going to call it a review and not an introduction. Anyhoo thanks for the heads up on this.. I'm looking around for good sources of cheap pico boards or even the chips themselves. Cheers,
@@LearnEmbeddedSystems video length is a valid concern, good point. Maybe a second more in depth one if requested by viewers... And there is your time investment too in the video production. Cheers,
Not sure I agree with cheap. the ESP 8266 chip approx £0.97 and what is the prices diff for the bigger flash. > £0.50? And they have dropped the buck/boost Didn't someone say the pico are made by Sony in the UK? You would think someone would be able to sell a PR2040 + ESP 8266 chip on the same board for close to the £3 of the Raspberry ones. I
IT'S A FRICKING PICO WITH AN ESP! At this point why don't you just use the ESP and ditch the Pico? Just think about it, when you go production, you will have to set some space for one more chip, you also lose one UART.
