The only easily identifiable pin on the FIT0272 is the GND! To which pins on the ESP8266 do I connect the others
T / R+T / R-RXD+RXD – already know GND… these are non standard identifiers
On the ESP8266 good chance that I got the VCC and GND right… I’m guessing I need to match up the RXD,TXD and RST pins which are named according to standards…
And Aidan, I figured out how to load the ESP Community board, now all I need to do is work out how to connect to the computer with the adaptor
I read Aidan’s post… link was supposed to take you to a “cable” … it went to an adaptor not a cable!
Still not sure what cable Aidan was talking about… to “hobby” Arduino person the descriptive was ‘black box’ speak, made no sense to me at all…
In my engineering (Mechanical) I have had a bit to do with CANBUS and PLC’s which is why I am interested in playing with Arduino IDE. When you start talking having to “flash” this and ‘convert’ that just to make a breakout board run next to a NANO (for example) is frustrating when you can’t just get shown what you have to do to make it work!
As an example I am having an interesting technical conversation with Texas Instruments about INA219’s… they can’t work out why I’ve smoked three of them on a simple PWM drive circuit… I know I should have stopped after the first one but I knew I hadn’t done anything wrong in the application… I’ve wasted hours testing with DMM’s and Oscilliscope to help them work out what’s wrong…
So, on Monday I’ll order the adaptor you have recommended to get the ESP8266 connected and give it a go…
The link in that article was indeed to a cable. Or, more correctly, an adapter with a cable on the end of it. The link was in response to a query that implied a different model of ESP8266 - one with a different pin arrangement. You can look at three significant examples to see the development.
The ESP01 had a 6-pin header. There were USB adapters designed exclusively for this board, or you could make up your own UART cable.
The ESP12E simply had two (or in some cases three) rows of headers. AFAIK there were no specific USB adapters for these modules, but they were easy to use with a breadboard. That type of module would use an adapter with a cable attached, so it could be reconfigured as required. Serial ports weren’t much used but you could do a custom cable if you wanted.
The FIT0272 cable you current have doesn’t seem like the best suited choice for your application. I would recommend having a look at the following USB to serial converter:
This particular adapter has a fair bit of supplier documentation about the usage of the converter. You can find that documentation at this link.
@Samuel while I agree with a good general purpose UART adapter, I think the key thing from this thread was the OP wants to build up to learning how to wire things.
To simply program the controller ideally something with the reset and PU pin auto managed would make like much simpler (as per @Jeff105671 ), or use a board with all that built in.
e.g. On my ESP32 S3 Mini, while it has the USB port, I still need to press and hold the “boot” button while press and release the reset button to put into program mode. Its this sort of thing I think the OP wants to avoid for now.
Cheers
In this respect the C3, with the reset issue and the CDC setting, is roughly equivalent to the ESP01 - as simple as it can be made, works OK provided you manage it right, but very easy to integrate into projects. You have to move to the larger, more power-hungry but more complete dev boards to get the simplicity of operation.
Maybe it’s a good idea to step back and look at the bigger picture.
@NATTI152417, can I ask why you have landed on the ESP8266 for this particular project? While it is a fantastic little board, these ESP variants can be a little obtuse when it comes to the setup.
Would something in the Arduino family of boards be more suitable for learning to work inside the Arduino IDE?
My son bought me an Arduino MKRIoT1010 and with that I made a data logger and was introduced to the Arduino Cloud and got all exited and bought the ESP01’s to expand on that learning pathway… I do know my way around the IDE. I got side tracked and now 18 months on I’m getting back into my learning pathway with WiFi , Bluetooth etc and had the ESP01’s in the tool box…
That’s where we were up to on Friday… on Saturday avo I found a fantastic tutorial on ESP8266 and the clever fellow solved the serial issue with a UNO board… I have a few, did what he did, wired the example up and now I have comms with my ESP01’s blinking away next to me as I now move onto the WiFi setting up… here’s the link
What I have discovered is some very helpful people who speak to learners in a forum in a respectful way and that is very much appreciated Jeff, Michael and Sam…
Of course I will be recovering my UNO board with the proper cable/adaptor but for now I don’t need it for these exercises
